 |  hard starting 390 -- craig R, 06/18/2005
Can't figure it out. Everything tells me that the car is in perfect tune. 390- 1961 T-Bird. 5,000 miles on rebuilt 10 over motor. Idle 620 RPM, 16 inches Vacuum rock steady. timing is 6 BDC. Compression is 162 high and 158 low between all cylinders. After sitting 5 minutes, cranks and cranks, just won't catch. If I let go of the key while cranking, it will run, but it just does not start like it should. I just rebuilt the carb, autolite 4100, and it seems to be fine. Once running, it runs great. Pertronix kit barnd new, all new plugs and wires. Verified TDC on Balancer and distributor poining just before #1.
What did I miss?
Thanks!!
Craig

 | Need 428 CJ Main bearings -- Mark, 06/18/2005
Desperately looking to find a complete set of 428 main bearings. Need to be .001 under
If anyone has a set or knows where I can locate one, PLEASE let me know!!
fishhog4u@yahoo.com
Thanks in advance! |
|  | Are you serious? -- Royce P, 06/18/2005
.001" undersize?
Ford had assembly line parts that were color coded for .001" - .004" undersize but they were not generally available to the public.
Typical undersize bearings are .010" - .060" undersize. They are available anywhere.

| Help ID A C4AE-6015-A -- Clayton Nantz, 06/17/2005
Hello,
I've got an old 64 Ford FE engine that I have torn down to see what it is and It has about a 3.75 stroke - which leads me to believe it may be a 390 does the casting # on the block C4AE-6015-A support this and if so how can I check to see if it's an interceptor - Thanks Clayton |
| Carb Spacer -- Jerry, 06/17/2005
I am wondering if I need to put a carb spacer on my FE Police Interceptor aluminum manifold. The manifold is on my 1968 428 engine with 4bbl Holley. Previous owner had none. I'm changing carbs and hoping to improve overall idling, etc.
Thanks!
p. s. Where can I find one? |
| fe and tranny chnage - 64 galaxie to C6 auto -- glennz, 06/16/2005
64 galaxie 390 with what some call the cruis-o-matic, want to upgrade to c-6 and larger convertor
have a c-6 column shift trans ready to go, and will be buying an 11 inch convertor
questions are
1. flywheel from 390 and cruisomatic, will it fit the bolt pattern for the c-6 convertor
2. is this a feasable swap with no side affects
3. trans mount, crossmember, and slip yolk for drive shaft ??
4. any other unforseen issues with swap
thanks

the trouble. |
| | | | RE: Unless you are racing , it really not worth -- glennz, 06/18/2005
i do not think there is much of a selection in convertors for a cruse-o-matic, the 390 is slightly built and a convertor change is in order, plus a shift kit of some sort...
so there is my delima, this is a customer car and this is what he wanted,
just making sure i am not going into something that can not be done, customer will pay the price to get done, just looking at unexpected parts interchage
that is why i was asking about part interchangablilty

| 390 bad vibe still-----------help again please -- genes 390 vibe still------------, 06/15/2005
ok guys this problem did not exist until new tranny was put in so 1000.00 later the tranny guy runs engine with no trans an says the vibe is engine, ok so engine guy runs engine with no belts an says yep thats it engine under warranty so the company sends new long block kool, not 853.00 later still got vibe it has new vib damper all parts matching original equipment vibe still at 12oo rrss and up vibes in park over 1200rrs in gear?? i thought it would get cured by now the engine guy says how deeps my pocket cause he really dont no what it will take ! any more help id be greatful thx |
| | RE: 390 bad vibe still-----------help again please -- John, 06/15/2005
Was a new bellhousing put in? If so, was a dial indicator used to check the runout? i.e. does the tranny shaft line up with the crank properly? Other pronblems could be torque convertor (maybe it was cut aprt and not balanced after it was welded back together). Is flex plate OK? Wasn't one for a 428 by mistake? What about further back.....u-joints in driveshaft OK? Internal probalems with transmission shouldn't cause a vibration, although I suppose it could |
| | | RE: 390 bad vibe still-----------help again please -- giacamo, 06/15/2005
take the fly wheal out and have it checked for balance it should have a zero balance for the 390 may be a weight fell off? i,v converted 390, flywheals to 428 specks by drilling and welding to counter weighting them but the 390 should be a non counterweighted true zero tipe of balance. |
| | | | RE: 390 bad vibe still-----------help again please -- genes 390 vibe still------------, 06/15/2005
yes flexplates have no wieghts just drill marks there r no weight as i have a couple to choose from ., they have been replaced 3times hoping that might be it along with torqe converters after a total of 1800. plus dollars and bolts getting worn out from being apart an together im not the kind of guy who gives up so this is not counting the times ive done the r,r on trans 2 tymes myself, |
| | | RE: 390 bad vibe still-----------help again please -- genes 390 vibe still------------, 06/15/2005
the flexplate has been checked matched re placed 3 new torqe- converters later so we had old one replacedcut washed re welded rebalance to 0, tranny out 4 tymes engine out twice then replaced used old vibe damper then bought new 1 there r no old parts left and this problem only showed up afternew tranny installed, again remember the engine has been run with no trans in it and vibes there in 2nd new engine. |
| | | | RE: 390 bad vibe still-----------help again please -- John, 06/16/2005
you don't suppose it is a misfire? One plug with no spark can cause vibration....just thinking of what still may be there from the old engine |
| | | | | RE: 390 bad vibe still-----------help again please -- gene s, 06/16/2005
both engines where put on the shop scope and read outs r as follows #1-92#2-92 #3-98#4-87#5-97#6--95#7-94#8-96 this at 1500rrsthats the rpm dropfor each cylinder.when you gas on it hard you cant really feel it but just above idle the mirrors shake and its not cause there a big cam hell this is all stock except dual exhuast. but ill double check it. thx open to all ideas i wont quit till i get it just tired of know wrench heads in my area not smarter than me, an that doesnt take much. thax again and if you have more ideas my minds open for any offers |
| | | | | | RE: 390 bad vibe still-----------help again please -- giacamo, 06/19/2005
is the intake cracked or burned out from the crossover exaust ports? i sean a 391 truck moter run ruff becouse of this under the tin cover under the intake it looked like somone used a welder on it and it was burnt through to the intake ports and towards the tin cover it was run on propane . and sometimes propain couses conpleat intake and vehicle melt down.i,m sure your ap is gas this might give you somthing to look at? |
| | | | | | | RE: 390 bad vibe still-----------help again please -- GREG F, 11/27/2005
i hope you didnt install a 410 or 428 flex plate does fan blades look ok 3rd how is trans and engine mounts greg f |
| | | | | | | | RE: 390 bad vibe still-----------help again please -- Bill F, 01/05/2006
I assume the carb is the same for both engines. If there's some dirt in the wrong place you could be getting a lean misfire when increasing the rpm after transitioning off the idle circuit. If you have found the problem please let me know what it turned out to be. |
| | | | | | | | | RE: 390 bad vibe still-----------help again please -- greg f, 01/05/2006
still a vibration or is it a miss off idle does it vibrate in park or in gear or on acceleration ther is alot of good input so lets shed new light on this let me know greg f |
| Engine mount problem? -- Clayton Nantz, 06/14/2005
Hello,
I have a 1969 mach I and bought a 390 out of a galaxie (at least that's what I was told - casting number says C4AE6015A whatever that is?? I'd like to know) and it runs great but I cant put it in my car because the mount holes on the engine are different from the 69 model - is there any way of conerting this motor or using different mounts to make it work? I appreciate in advance any help guys! |
| Help Identify CJ Parts?? -- Anthony, 06/13/2005
I have a long list of ford part #'s that are supposedly 428 Cobrajet parts. I would appreciate some help identifying the following:
Crankshaft: 1U with a "A" under the 1U, has a 11 on one end of the front counterbalance and a 12 on the other end of the same balance.
Heads: C4AE one has 8090G, the other 6090G next to the C4AE.
Two sets of rods: one set is C7AE-B
the others are C6AE-E
C6AE-E rods have C8AX-6110C pistons attached.
Intake: C7AE9425F (aluminum)
Flywheel: C80E-A
The Block: 9B26. "C" in rear of casting, 352 on back & front. "E" on casting also.
Exhaust manifolds: C80E8431B & C80E8430D
Another block has 66-427 and the "C" in the rear casting with a 9D10.
Also, a "whats it worth" for a set of 428 Cast Aluminum cobrajet valve covers, and a set of original Shelby valve covers with the Shelby American stamping on the inside.

"Crankshaft: 1U with a "A" under the 1U, has a 11 on one end of the front counterbalance and a 12 on the other end of the same balance."
1969 428SCJ (before 26 December 1968) C9ZZ-6303-A 1UA
http://www.428cobrajet.org/id-crank.html
"Heads: C4AE one has 8090G, the other 6090G next to the C4AE."
These are good "high performance" FE heads to be sure but are not CJ variety.
"Two sets of rods: one set is C7AE-B
the others are C6AE-E
C6AE-E rods have C8AX-6110C pistons attached."
C7AE-B = 428CJ rods
C6AE-E = 427 Lemans cap screw rods (used on 428SCJ motors)
"Intake: C7AE9425F (aluminum)"
This is a 428 police interceptor intake. Just like the CJ but made of aluminum.
"Flywheel: C80E-A"
This is a 428CJ part
"The Block: 9B26. "C" in rear of casting, 352 on back & front. "E" on casting also."
Need more info. Check out this link
http://www.428cobrajet.org/id-block.html
"Exhaust manifolds: C80E8431B & C80E8430D"
428CJ part numbers are:
C80E9431B
C80E9430D

| | | C8AX-6110C pistons -- Jeff H., 06/15/2005
Here is some info I got from another forum on the identity of the pistons.
"I'll bet its a Dyke ring 12.5-1 427 piston in an oversize but I just read the thread and now realize that you posted a casting number not a part number so it may actually be a standard 427 piston. The C8AX-6110-A was a standard 427 Dyke ring 12.5-1 piston and it is not unusual for a casting number to end in a different number than a part number. Have him measure it." |

| Engine Vin -- Nathan Hooker, 06/12/2005
How do you find out if you have the original engine do you use the casting numbers do the blocks have part of the vin number stamped on them. Or do you use the casting number Thank You Nathan |
| | Casting numbers and date codes -- Royce Peterson, 06/14/2005
The parts had to be made before the car was built. They also have to be the correct parts. Post the casting # and date codes and what the actual manufacture date of your vehicle was and we can tell if they are correct or not.
