Should I buy a Ford 391 engine?

I have a chance to buy a 1974 Ford F600 that has a 391 in it. I am thinking about buying it and putting the engine in my 1955 Ford sedan delivery. I have been reading about the differences between the FE And the FT engine but I have found nothing about the differences in the weight. Is the FT a lot heavier? Or should I buy the 391 and put it in my 1972 Ford F350? Then take the 1969 390 from my 1972 F350 and put that in my 55.

They are both heavy compared to a 351windsor which can be stroked up to 427ci. If weight is a concern you may look into stroking a windsor which probably has more performance parts available at reasonable prices.

The FT Series was built to power medium duty trucks. It is no heavier than an FE other than the block is cast stronger and it has a forged steel crank. Some can be bored to attain a 4.13" bore (and for awhile was the service replacement block for both the 390 and 428CJ). The front crank nose has to be machined down to passenger car size and then the complete FEAD asm from the FE can be mounted (including timing cover). The heads and intake manifold are not performance orientated and they would also have to be replaced.

Hope this helps you make your decision.

Duke/KULTULZ is ok on the crank stuff.

If you don't want to disassemble the engines and make the 391 into a 390, I would put the 391 into the truck and the 69-390 into the car. The 391 front accessories would be better in the one ton. and the 390 one ton can be dressed like a car engine in the SD.

That's a lot of trouble to save a couple bucks.

I bought that F600 with the 391 in it today along with a 1990 F250 4X4 with a (bad) 4.9 and a 5-speed.

The 391 is not stuck but the starter is laying inside the cab. They claim the fly wheel has the wrong ring gear but my brother tells me that they probably tried to use a starter from a vehicle with an automatic transmission and it didn't work. He tells me that Ford had two different starters one for automatics and one for manual transmissions. From the looks of things around there I think they run into this little starter problem and just went and bought another truck.

They had also stuck a big old Holly double pumper on the engine and the sellers told us it really went through the gas after they put that on.

keep in mind aftermarket intakes such as edelbrock will not bolt up to the ft heads.

turn it into a 427 and drop it into one of your mavericks.
