| 390 problems, need help bad!! -- Justin, 11/07/2003
Hey guys houston has a problem. About 3 years ago i bought a 1965 Galaxy 500 that had a 390 in it, although after i bought it i was able to drive it home (all together about 20 miles) but it kept dying on me on the way back. So when i got it here i tore into it finding out that the gas that was in the tank had varnished and went into the heads lol. So i proceded to tear it down and revamp the heads. Everything went fine untill i was tapping the rocker shaft bolt holes and my tap broke off in one of them so i had to get a new head. After i got everything put back together it still wouldnt run correctly and timing was way off no matter what i did, so i tore the front of the motor down and replaced the timing chain (which had jumped a tooth) and went ahead and replaced the cam and lifters as a safe measure. Well after i did all this and switched from a 2 barrel to a 4 barrel i was ready to try it again but to no suprise the thing didnt even want to give the slightest sign of wanting to start. So i messed with the timing a bit and finally got it to run somewhat, it was like no matter how far i pushed the peddle down it didnt accelerate and i had to keep on it to keep it running, so i shut it down so i wouldnt mess anything up. This is where i am at now i cant seem to figure out what the heck the problem is, i have pretty muched tried everything including putting the different lengthed pushrods in to adjust it and that didnt work, it just doesnt want to run period. It makes me feel horrible i am a certified Auto Tech and i cant figure it out i have never had anything like this and this is my first FE. Anyone have any suggestions on what could be wrong? I need help this is starting to get to me lol. Thank you. |

All ways like to start with 1st things 1st, Did you clean gas tank, fuel filter, carb? Have you checked the points? Spark at plug? Coil? Firing order? All vacume hoses? Choke on carb?
Charlie |
| | | RE: 390 problems, need help bad!! -- Justin, 11/07/2003
Thank you for your reply. the gas tank was replaced with one out of a 1967 Galaxy and i cleaned and sealed it before putting it in. fuel filter, points, coil, and all vacuum hoses have all been replaced with new. and the carb was rebuilt it is a holley 600 (1850). although i have always wondered if that carb was actually sealing corectly on the stock manifold, i am currently getting ready to try a ford 4B on it to see if that helps. And there is spark at the plugs but it seems speratic and doesnt beat it time it seems, but i went through my distributor last night and nothing seemed out of the ordinarry except for that the ground wire was a little loose. Of course that could be it lol. But if you think it could be anything else please let me know. Thank you again. |
| | | | RE: 390 problems, need help bad!! -- Justin, 11/07/2003
Oh and to add to that last thread that i made all of the fuel lines have been replaced also from the tank to the pump and from pump to carb, and they are bent exactly like factory i did it myself to make sure of that and there are no kinks. |
| | RE: 390 problems, need help bad!! -- Glenucci, 11/07/2003
After similar problems, a compression test led me to stuck valves and bent pushrods. |
| | | RE: 390 problems, need help bad!! -- Dave, 11/07/2003
I had a 289 that ran bad after rebuidling and the distributor was 180 degrees off. Turned it to where it should have been and ran great. Havnt had that problem with my BB. Good luck |
| | | | RE: 390 problems, need help bad!! -- Justin, 11/07/2003
Yeah i have not tried a compression test yet, that was one of the next things to do if i can find the compression tester to do it with lol. maybe that will lead me to my cure. |
| | | | RE: 390 problems, need help bad!! -- lenny, 12/05/2003
o.k. justin, from your post you state you are ase cert, but bear with me as we start with basics, or KISS 1: do you have an adequit fuel supply to the carb? verify volume and pressure visually. 2:is the fuel getting in to the carb? fuel filter unrestricted, floats at proper level,jets clear and passages open? (no, a can of berrymans is no guarantee) 3:good, crisp, blue spark? not some half orange to yellow color. 4: check for shorted points/ bad condenser |
| | | | | RE: 390 problems, need help bad!! -- lenny, 12/05/2003
5: sufficient voltage to coil?both start and run sides? 6: worn or misshapen dist lobes or any shaft play in dist.? 7: corect type of coil for your application 8: shorted tachometer or wired incorrectly 9: proper re-installation of dist( a couple of teeth off is a very common problem on fords with the hexagonal oil pump drive) 10:correct alignment of timing set 11: didyou install the pin in the front of the cam when you put it all together? 12:correct firing order? |

| | | RE: 390 problems, need help bad!! -- bill, 12/14/2003
if you have to keep your foot in the gas just to keep it running & timing adjustments do nothing check exhaust pipes had one come apart from the inside & block the pipe if it cant breath it wont run goodluck |
| | RE: 390 problems, need help bad!! -- giacamo, 11/07/2003
Juston did you put a big ass cam in it and not check piston to valve clearance....... |
| | RE: 390 problems, need help bad!! -- MickMan, 12/05/2003
First -- go back to the three basics for an engine to run: compression, gas, and spark. Check each one at the cylinders.
Those old gas tanks can produce a lot of rust that will fill up filters, carbs, and lines.
I'd even take the fuel line off the carb and crank the heck out of it to see if its getting gas. I had to completely replace my '67 tank because the crap in the tank, even after completely cleaning it, completely gummed up the whole system. Finally used a glass fuel filter to watch it flow. |
| | 361 engine trouble -- Darrin, 11/05/2004
I recently bought a 1970 boom truck, with a 361 engine. It has been Idling well, but backfire's on coasting, or letting off the throttle. I installed a new muffler system dual exhaust. Then proceeded to the tune up. I noticed the plug wire's were not on their designated timing order. So, I change them to the 15426378. I get spark at the points, crank at TDC, and can not get this to fire over. What is proper distributor location according to the block? Is there two different firing orders for this motor? Also can you help? |

| fe heads possible 427 -- 67stang, 11/06/2003
have a customer that is tearing down his motors (2) for rebuild, the block castings on both say C7AE-a which would correspond with his claim they are from 1968, my problem runs into head casting numbers, this is what he says they read Heads - C7JE-6090A one set C4AE-6090C the other set
what are these what are the differences, are they possibly marine heads, are they low risers any specifics please would help. all my books show that 6049 should be the second set of numbers not 6090...

do thay have 2.02 1.55valves or 2.185 1.733 valves......the C4AE set are problie1964 standard heads check the valve spacing 427 heads have a slighly loger valve spacing then standerd heads to acept the larger valves try to find a standerd set of heads measur valve spacing and compare them with yours. i have sean some small valve heads measure to the the wide and wear abel to instal the larger valves,the c7je heads may be intersesting? |
| | Re:c7je -- McQ, 11/08/2003
The third unit in -J- indicates Industrial/Marine application. They may be the low horsepower 427 Marine heads or they could have been on some type of industrial application 427/428/390, orchard wind blower, irrigation pump, etc. I think they have valve/port size like a standard 390 head. |
| | | C7JE is a Chris Craft marine head -- P, 11/08/2003
There were other marine applications too, such as INTERCEPTOR. The Interceptor motors were similar to those sold to Chris Craft, I understand for around $1400 each, but Interceptor also offered at least two higher horsepower versions up to 400-hp. The CC versions were all standardized around the 300-hp spec., and those were used in anything from a fiberglass Commander to many wood Cruisers, some of which were very large, as well as a variety of runabouts. Even the Italian Speedboat manufacturer "RIVA" was known to use an occasional big Ford.
I understand the C7JE heads were generic 352 and 390 units, that could be cleaned up and used for performance applications. I have a set sitting in my office now if anyone wants the particulars lemme know, all I have to do is walk down the hallway.

| What do you guys think about Intakes? -- Nash, 11/06/2003
Im going to be searchin for an intake soon for me 390 FE.
I'd like to get a tunnel ram intake, so I can have somewhat of a ''stacked'' street motor.
Is there any affordable tunnel ram out there?
The blue thunder dual quad carb intake looks interesting, but does anyone know the performance of it compared to the Edelbrock RPM?

| Radiator Identification -- Mike, 11/06/2003
Hi all - i recently replaced my stock 2-row radiator in my '64 galaxie, 352ci, with a 3-row from a local classic car junkyard - they had the radiators in a shed - and has a 30 day warranty. Seems to be in good shape - and no leaks (my other one was like Ol Faithful). Question i have is if anyone can identify it - its definetly fomoco - and the guy thought probably came from a 400ci+ engine - the part # is : GIC3AE8005 small letters say J2K18A
Basically same dimensions as my stock - but thicker (3-row). Just curious where it may have come from -
Also - when i sit in traffic, from time to time i get plumes of smoke coming from the sides of my engine - smells like oil - comes and goes - and usually only while idling - but doesnt happen all the time. I burn about a quart of oil every 200 miles (not good i know). I need to rebuild engine soon - but wondering if anyone had any ideas on the plumes of smoke thing - thanks |
| | RE: Radiator Identification -- giacamo, 11/06/2003
i,d say it,s looks like it came out of a 63 mercury.your engine probly just blowby puffing smoke setting still.wen you moving the air keeps it disperced from under the hood..... |
| 390 head dilemma -- BarryMcLarty, 11/06/2003
Have been on the side lines for 10 years,and am now using all the fe parts left in my garage from my drag racing days to build a 64 Galaxie liteweight clone.I am going to use a 71 105 block,tri power ,headers,4:11 gears,and am considering a C6 so I can do some bracket racing.I was wondering how much compression to use with todays fuel quality,and what heads to use .I have a set of 66"R" heads ,and can get a set of Edelbrock aluminum heads from a friend.I will be 390ci,and need some advice on which pistons will work best with each style of head.Also,can the "R" heads be made to flow in the same ballpark as the CJ heads?The ports are big enough,but the exhaust side will need some tlc to eliminate the transition to the headers.Is it a better and cheaper way to go to just buy the Edelbrock heads,than to spend monney on the "R" heads?thanks |
| | RE: 390 head dilemma -- giacamo, 11/06/2003
Barry are the r heads c6ae 6090r with 2.195 1.733 valves or standerd 66 r,s with 2.02 1.55 valves.on pump gas i,d only go up to 10.5 compression.. |
| | In the long run, the pro's suggest: -- Nash, 11/06/2003
Go to RPM setup.
They are aluminum, raise compression up .5, contain big CJ valves, and light!
I have a pair of C6AE-R heads, they are great!
Fill me in!
Nash |
| | | RE: In the long run, the pro's suggest: -- Nash, 11/06/2003
Youll really wind up paying alot to sup the c6AER heads up if you really price to price things.
Just my .02 |
| | | | RE: In the long run, the pro's suggest: -- BarryMcLarty, 11/06/2003
You are right.Local head man says to straighten the exhaust runner(eliminate the dead areaon the side of port) and put in larger valves will cost$!Ok.now to find some forged pistons that will give me 10 or 10.5 to 1 comp with the Edelbrock heads.Thanks. |
| | | | | RE: In the long run, the pro's suggest: -- Nash, 11/06/2003
I have the speed pro pistons with c6AE-R heads.
The pistons are rated at 10.1:1 with a true 68 CC head.
You'll also find out that the C6AE-R's are rated at 72CC's, they are really 76CC's upon tests.
So With those speedpro pistons and C6AE-R heads- that around 9.1:1 compression.
With edelbrock heads- its 9.6:1.
My aim is Isnoforum
Email is FendersRule@aol.com. I can straighten some things out for you :)

UEM-KB150040-8 Pistons, Hypereutectic, 4.090 in. bore, 2-5/64, 1-3/16 rings, Flat Top,Set of 8 11-16 $217.99
I have run 2 sets of these one with cj heads from edelbrock one in a set of cj heads original c8oen. Both 390's 40 over with simular cams (236*i 242*eh). They require a larger ring gap in the top ring but the lighter weight allows quicker revs. The web site is down for repair but they do list comp ratios. |
| | | | | | RE: In the long run, the pro's suggest: -- BarryMcLarty, 11/07/2003
Are these KB pistons copies of the stock 390 GT pistons with the same valve releifs?Also,how do you like hyperteutic compared to forged?The price is definetly right. |
| | | | | | | RE: In the long run, the pro's suggest: -- Charlie, 11/08/2003
They are not copies of originals. My machinest recommended them to me and I haven't looked back since. My brother has a 390 w/ cj heads and same cam in his 69 mach with fed. pistons. My 390 seems a bit snappier than his, could be in the ignition? but the lighter recipicating mass has too help. I'll try to post a pic of installed piston tonight. Charlie |
| Anyone know timing and point settings for 390? -- Steve M, 11/05/2003
I am getting ready to time my car and put new points in it. The motor is out of a 1970 galaxie and it is a 390. I need to know what the timing setting is and the point gap if anybody knows.
Thanks. |
| | RE: Anyone know timing and point settings for 390? -- Glenucci, 11/06/2003
My 1970 390-2V calls for 6 degrees BTDC and .017" on the point gap. |

| | | RE: Anyone know timing and point settings for 390? -- 63 galaxie man, 10/06/2004
Timing for a 1963 4v 390 motor is 8 degrees and some up to 10 some differ on each motor but 8 degress before top dead center is a good accurate start. also points gap is set at 14 if a little aggresive try 15 to 16 max should solve it from there. |
| | 390 is purring like a kitten now. It was ret 24 -- Steve M, 11/08/2003
I cant believe this thing even started. Here I am putting a new carb on the thing and I still had a backfire problem. The timing was retarded 24 degrees. In celebration, I took my galaxie on the street and did a starsky and hutch donut in because the thing runs fast as h*ll now!! Thanks everybody for your help! I can now say I am happy with my motor swap! I cant wait to put the cam and PI intake on it this spring and see what she will do... |

| bent pushrod and seized valve in rebuild -- Scott, 11/05/2003
Ouch … A fresh rebuilt 390 w/ hardened exhaust seats installed, valve guides etc done at a machine shop. I followed the 68 Ford shop manual when putting the motor back together. I started the motor and made sure the heads were getting oil. Everything looked fine. I could see the heads getting oil, all the pushrods, rocker arms, and valves moving properly. The other night I started it and let it run at 2000 - 3000 rpm's for 15 minutes. Then I started to hear a steady “ting noise” coming from the head. I removed the valve cover and found a bent pushrod and a seized valve. Any ideas of what I did (or did not do) wrong? Thanks, Scott |
| | RE: bent pushrod and seized valve in rebuild -- giacamo, 11/05/2003
problie valve gide to tight to start with. or if its a exaust valve you haft to make shure the gide douse not extend into the port the exaust gass will heat it up and cause the exposed gide aeria to sease on the valve. thay needto be trimed flush with casting. i,v sean this befor......... |

| Power steering hoses for 69 390 -- Jim, 11/04/2003
Can someone direct me to someplace I can find original assembly/parts diagrams showing what the ps hoses on my 69 390 (w/ a/c) are supposed to look like? My shop manuals don't have the specific drawings I need. Then I've got to find a place to get 'em. Thanks for any help you all can provide.
Jim |
| | RE: Power steering hoses for 69 390 -- jake, 11/06/2003
Don't know about any diagrams. Have you checked the regular auto parts stores? I bought PS hoses for my '65 at NAPA a couple of years ago.
As an aside: there may be more than one steering box or PS pump available on your year car--there was on mine--take a good look at both so that you can identify them at the parts store in the catalog. |
| | RE: Power steering hoses for 69 390 -- Charlie, 11/06/2003
Napa will have a set of printed ref. books showing the hoses. After 67 to 70 I believe the 390's got a 2 part hose and the small blocks got a 1 piece pressure hose. The big thing is to make sure if you have a 1/4" or 5/16" fitting. The pump side is the same on both but the control valve isn't. You can get the hoses from Mansfield Mustang, Mustangs unlimited etc.... I found Napa's price to be best, took 2 days to come in. Charlie
PS If you're replacing the return side all you need to buy is hose from any auto parts store, its not worth soending the extra cash to get the metal parts, they usually don't wear out. |
