|  | Getting to be a popular swap -- Royce P, 11/12/2005
Since the FE with aluminum heads and intake is not much heavier than a 351W this has become a fairly popular swap. Several people on the other FE forum are running cars so equipped. Go to http://www.FordFE.com and search Fox body FE.
I don't think there is actually a kit, these guys are using a motor plate and modifying the stock tranny crossmember if I remember correctly.

should have seen all the FE equipped vehicles in the roush exhibit at SEMA this year, they act if it is something new
nice set-ups,

| | | | Roush is up to their ears in FE's -- Royce P, 11/14/2005
Roush is the final machining vendor for the Genesis 427 blocks and is involved in the FRPP 427 FE crate engine program too. No doubt it is in thei best interest to promote the FE.

so those were the ever so mysterious genesis blocks, looked good, had one in a mid 60's pick-up and ten a few others on stands all around the exhibit area..
they had a nice exhibit with a few gt 40's and some cool rods...didn't see jack though
boyd looked as stupid as ever and foose was doing up a 66 charger live...
never been to sema, first year, spent 2 days there and did not see everything, looking foward to next year

 | 390 revs to 4500 and thats all... -- Anthony, 11/11/2005
I have a 67 390 Mustang with stock intake and exhaust. Engine will rev to 4500 and thats it. I can accellerate to 4500 in 2nd gear and it will fall flat at 4500, but a shift into 3rd and it will pull real hard again until 4500. I have pulled the rocker assy's off and a couple of the valve tops look like they have been hammered pretty bad. Can this be valve float from old valve springs? If so,what would be recommended for a replacement spring?
Thanks |
| | RE: 390 revs to 4500 and thats all... -- John, 11/11/2005
Only things I have seen to cause this are:
Crank/cam chain off by a tooth
Plugs (platinum wire elctrode type) worn out
Improper valve lash (Zero in my case) |
| | The simple things -- raycfe, 11/11/2005
Are you getting full thottle? Have somestep on the gas and if the thottle is open all the way. Just my 2 cents |
| | Coil could be going south. -- Wayne K., 11/11/2005
A coil can cause that, deteriorating to the point it wont rev much past 1500 or so (happened to me).
But it could be as simple as 38 year old valve springs. I'd be surprised if it WASN'T the valve springs if they are original.
Another thing that can hamper, but maybe not stall, acceleration is if a timing set is installed advanced, especially a high torque style cam. Advancing those really pumps up the really low RPM grunt but does very bad things to upper RPM power.
Yet another thing to check:
Fuel pressure can do strange things too. If the fuel pump / lines can't keep up, then of course the engine can have similar symtoms.
One last mention:
I knew a guy once (not me really!) who had a super small air cleaner (REALLY small). and it sat very low on the air horn of the carb so it would stop pulling at higher RPM. Imagine that.
Good luck,
Wayne

| | | more explanation.... -- Anthony, 11/11/2005
Thanks for the responses guys. It has been doing this for a few years. I have done everything from a full tune-up to replacing the oil pump (High volume), rebuild carb, replace pushrods(some were bent), adding an electric fuel pump, changing the timing chain set, etc. The engine also has a clacking sound under accelleration, (not pinging), which goes away at cruise. The same sound seems to appear at 4500, but it gets hard to hear over the exhaust, etc. It is not a bogging sound that you would get if it was starving for fuel.
Keep em coming.... |
| | RE: 390 revs to 4500 and thats all... -- PaulStibbe, 11/11/2005
Anthony the first thing you realy sould do is test the valve springs. You didn't mention the camshaft your running. It's posible you may have.a R.V. or low rpm torque type cam. These cams use a very short duration with a high lift this works great for low RPM power but these cams will not rev much past 4 grand due to the lift/duration ratio
If you have this type cam your flooting the valves for sure by 4500rpm, Even with resonable valve sping pressures. hope this helps. Paul
|
| | | RE: 390 revs to 4500 and thats all... -- Anthony, 11/11/2005
I do not know what cam is in it. Is there any way to measure the lift/ duration in the car? Please give me some pointers. Also, do I have a machine shop test the springs, or just replace them, but with what?
Thanks again.

| | | | RE: 390 revs to 4500 and thats all... -- PaulStibbe, 11/13/2005
There is a good article on how to degree camshafts at www.compcams.con. Paul |
| | | | | RE: 390 revs to 4500 and thats all... -- walt, 11/16/2005
and and over or late timed cam will not give you vavle train clatter.late timimg give you high speed horses,early timing gives the hole shot pull'you had toolose a lot of timing to cause your probs,stock ford bb springs are good to.525 lift(pushing them)with the right retainers and locksand iwas able to buz them to 7000 no probs |
| | | | RE: 390 revs to 4500 and thats all... -- giacamo, 11/15/2005
did you check for bent valves with the bent pushrods, some times that clacking sound is the valves being knocked closed by the piston? |
| | | | | RE: 390 revs to 4500 and thats all... -- Anthony, 11/15/2005
Good point- I will pull the covers and springs and see. |
| | | | | | RE: 390 revs to 4500 and thats all... -- walt, 11/16/2005
if you start beating your valve tips to death,not enough vavvle spring travel,bind,guides not machined for proper seals and valve travel,ps,maybe wiped the cam by now |

| 390 GT Block Identify -- Jerry, 11/10/2005
Need shopping tips to identify correct 390 FE block for my 1966 Fairlane GTA. What special characteristics should I look for that will identify GT engine vs. run of the mill FE.
Thanks! |
| | No difference between markings of 352,390,410,428 -- Royce P, 11/11/2005
A 390 GT block isthe same as any other 390 block of the same period.
Typical casting numbers for any displacement FE of the period are C6ME and C6ME-A. Look for one with a 4.05" bore and a date code before your car was built.
Royce

| | | RE: No difference between markings of 352,390,410,428 -- Jerry, 11/11/2005
Thanks Royce.
I was wondering if I should be looking for a block with an "X" in the rocker valley. I was told this means a higher nickel content. Or was this available only on the larger displacement engines? Also what would a bare 390 block be worth, ballpark? |
| | | | The X is meaningless -- Royce P, 11/11/2005
There are some nitwits / predators on Ebay who try and sell their parts with all kinds of stories. Bottom line, no FE block has higher nickel than any other.
A good usable 390 block should sell for $200 - $300.

| gearbox cross member? -- peter, 11/09/2005
69 428 Cj mustang gear box cross member? Auto Vs manual?
Are these one and the same or is there a difference between the 2?
Thanks
Peter. |
| | Significant difference. N/M -- Hawkrod, 11/10/2005
|
| | | | That is a C6 crossmember for a 67-70 390 or 428 -- Hawkrod, 11/10/2005
The stick crossmember is different and has 4 mounting ears instead of 3 and is slightly different from 67/8 to 69/70. Hawkrod |

| coolant holes -- robert furnia, 11/09/2005
dear sirs. i am rebuilding my 390 in my mustang. my new felpro gaskets have one hole in them plugged. my block has a coolant hole in the front and in the rear. the new felpro gaskets have only one cutout.the old ones i took out had the other hole cut out by a mechanic.do i leave the gaskets alone or cut them out.allso what holes will be pluggeg if so. front or rear. any help will be appreciated thanks bob |
| | Leave the gaskets alone!! -- Royce P, 11/11/2005
The gaskets are marked "front" on one end. Be sure you install them correctly!
Royce |
| | RE: coolant holes -- giacamo, 11/15/2005
for god sakes install the gaskets with the frount pasage blocked if not marked,,,,,,, I know one will look upside down,but it will be corect and whow ever cut the gaskets out in the front neads thear as%$^Y kicked. the water flowes in the frount of the block to the back of the engin to the back of the heads then back to the frount of the head to the intake. having the frount opened up makes the water flow a short rought and couses the engin to over heat thear is only a one or two speadboat aps for the frount pasage but 99% of the time thay must be blocked...... |
| Broken Valve rod -- Joe, 11/09/2005
Went for a ride sunday and broke down I thought the engine was toast. The valve rod broke on the end. The last valve is on the outside of the rod support and my engine guy said it is commom for them to snap there and probably more so for me because I have edelbrock heads which use a heavier spring. Is this B.S? Has anyone else had this problem? It has less than 1K on rebuild. Does someone make a stronger rod? I don't want to get stranded if I take a long cruise. He said I could put roller rockers on that add an extra support on the ends$$ Thanks, Joe

| cyl head info. needed? -- paul, 11/08/2005
Are these heads considered medium risers??C4AE-G and the C6AE-F are these considered performance heads ? what would the approx core value be on these two sets ?? kind of rusty with a few valves missing! -----------I dont know the FE's very well-- I spend most of my time on the 460's ---thanks Paul |
| 1967 engine cradle conversion? -- bill mack, 11/07/2005
I saw a few mustangs on ebay that were equipted with front crossmembers from late model fox body stangs. Does anyone have any info on this? how much fabrication is required? I have a late model donor car and would love to be able to install the p/s rack and disc brake setup into my 67 stang |
| 1967 390 air cleaner -- Tom, 11/06/2005
Just bought a 67 390 Mustang Fastback.Can anyone describe or send me a picture of the correct 390 air cleaner. this is not a GT. I do not know if that would make a difference. The one I have has a round snorkel. I think it is a stock 289. Thanks for your help. |
| | | He said he has a non GT, that's a GT air cleaner -- Hawkrod, 11/07/2005
It sounds as though he may have the correct air cleaner. It looks just like the one in the photo except it has a round snorkel that tapers down and does not have a heat stove (289 air cleaner snorkels do not taper down and have a heat stove fitting on the bottom and fullsize 390 snorkels are round without the stove fitting and also do not taper down in size). Check out this thread and follow the link to see the application from the MPC. Hawkrod |
