The older ones have higher compression, more torque, more hp.

You didn't mention which tranny...just make sure you use the correct flywheel...The 351M and 400 are both EXTERNALLY balanced, while the 429/460 are INTERNALLY balanced.

The flywheels will bolt up to either, but the wrong one will obviously put the engine out of balance.



What's wrong with the 351M??? I'm just gonna run mine till she blows, THEN worry about replacing it. They reallyar ok engines, just need a little money thrown their way.:D

The 460 wasn't availabe in a 4X4 till '83. The 460's before '79 are internally balanced, you will need a flywheel from a 390. (ford didnt have commonly available any stick shft 429/460's in the '70's) If its after '79, any 460 flywheel will work. Do yourself a favor and get a flywheel that will accept a 12" clutch. You might have to clearnace the belhousing to clear it. To tell which flywheel you will need, look behind the harmonic balancer, if there is a counterweight, any 460 flywheel should work, if there isnt, you need to find a FE flywheel (352. 360, 390). You want manifolds from a truck, or a van, passenger car ones wont clear the frame. Get 2wd 390 truck motor mounts and make them work. It will save you at least $100 on mounts alone


Hope this helps

while you are at it, if you get a FE flywheel, make sure that there is enough meat on it so that your clutch springs on the disc wont grab the heads of the bolts on the back of the crank. There is flywheel bolts available that have a shorter head than a stock bolt. Do not grind the stock bolts to make them work. (Dont ask me how I know this... :(
