Can pick both these up for $150.00 haven't seen yet figure the motor could be a 391 FT block anything to look for to tell difference between 330 to 391? 4 speed Trans. be good for anything other than a truck?


Thanks, Bill

Bill LOL I have the same problem except mines more complex

The dang cab has been crushed down so far the doors are stuck. The Shell said F500 and it has a 2 barrell. The front of the motors so burried under Aux drives etc that you can barely see the snout of the crank at the front seal to judge the size but it looks like common FE. It has the HD dist and monster oil bath Air Cleaner. looking at the numbers on the heads and intake I feel is next to worthless because they have likely been swapped out etc. The entire mess is burried under 35+ years of grease. Then the Junkie wants a few hundred and I'd have to pull it out...........

some of the valve covers have a decal on them that tells the engine size. Mine was a 361.

Don't the 331, 361, 391 engines have an odd distributor?

over bore a 330

March 3 2008, 10:46 PM 

I know for a fact that a 330 can be bored to 4.05" because I had it done. It isn't worth doing it though if you have a 390 block. The machine shop I used charged me an additional $80.00 to do the job. I have used the engine in my 76 Highboy for the last 2 years. You have to remember that when an engine is bored 0.030" over, that there is only 0.015" metal being removed from the cylinder wall so when a 330 is bored to a 390 0.0875" of metal is removed. That block has enough meat to do that overbore.

F-600 engine

Back in the 70's I was a Ford truck dealer partsman. I can tell you we sold many, many of those FT long and short blocks and the overwhelming majority were 361's not 391's ...so if you have to guess what one of these engines is, go for 361 unless it came out of a single rear axle city tractor...THAT application is where most of the legit 391's were that I saw.

391's were the most popular replacements around here...

I worked in the parts department at a large Ford dealer from 1969 to 1976. I delivered many 391's and 534's. Very few 361's, & probably no 477's.

does anybody really want that stuff?

March 4 2008, 2:18 PM 

I have a whole shed full of 361 and 391 stuff that i can't seem to get money for. I sold a 391 crank and the full sump oil pan and that was it. The early 70's 361 block i have has the "66-427" casting on the back and doesn't have the extra main webbing. I don't think it's worth buying a whole engone on the chance the block is a thick one.
