Well there is a tag on the engine usually that will say 391 etc.. There will not be a 352 ususally on the left front of the block just below the head. The main webs are reinforced and there is usually much more meat in the cylinder walls. The distributor hole will be too big for an FE dizzy unless you buy a bushing for it. The heads have smaller ports and they are always 4bbl engine I do believe.

Seth, It's a good chance that a 330 is in the truck also.

didn't the FT's have steel cranks? what parts will fit off a FE? the guy said it ran 5 years ago when he parked it. im wondering why he parked it. he says its a 390. i'll look at my grandpa's 330 before i go and then look at a 360 and note the differences.

The cranks were all steel and you can use them by grounding the snouts down and re keying them. I beleive they are balanced differently (externally) but I may be wrong. Almost all parts are interchangeable. But there are things like an FE intake would not work well with FT heads becasue of the differences in port sizes.

i looked at the 330 and the 360 my grandpa has. the crank snout is way bigger on the 330. the 330 still has 352 cast on the block and has a 2bbl carb. it has 3 engine mounts. 1 in front and 2 on the back crossmember. it has y-type exhaust manifolds like a ch*vy or some Y-blocks. now i will know what to look for. would stock heads off a 360 or something be better than the heads on the FT?

I can't think of any FT heads that would be good for a street/performance engine. The standard 360 heads would be C8AE-H or D2---- heads and both are plentiful and can be made to work excellent on the street. If you change heads on the FT to the FE heads, you'll want to change the intake too as the exhaust crossover is located in the center on the FT and on the sides on the FE.
One nice advantage to the FT is the block, the block is supposed to be boreable to 4.13 (428 size) and stronger that a stock FE block.

went and looked at it and it was a 391. had a four barrel intake, dual thermostats, and big pulleys. i went ahead and bought it and brought it home. i'm going to rebuild it with FE heads and a edelbroc intake. maybe a mild cam.
thanks for all the replys
will the FT dist. fit in through the FE intake hole

The FT dizzy will not fit in an FE but with a bushing that can be bought from ford the last I checked you can run an FE dizzy in an FT block. My block has the FT size hole for the dizzy and the FE bushing. Good buy and good luck!

I have a 1974 casting which was actually an FT block converted to an FE. Most all FE's were like this from 1973 - 1976 so I did not have to buy mine because it came from the factory with one. You can slap an FE crank in an FE block without any problems whatsoever as long as you have the FE balancer, pulley and flywheel.
