Well I just got another truck. I picked up a 78 F350, It has a flatbed on it now , but you can see where it had a dump box on it originally. It has a pto, and the truck was has a factory gvw of 10,000lbs. It was supposed to have a 400 in it but someone spent the time to put in an FE. Once we got it home I looked at the block numbers and the intake and it appears to be a 428. It may even be a police or cobra jet. (any hints on how else to tell would be appreciated) . The best part of all of that is I only had to pay $20.00 for it.

SCORE!!!!!

On top of that the guy threw in a 75 F250 parts truck with it.

for that price I'll assume that he just wanted it Gone. You didn't say if it would run or was drivable. Maybe you got lucky and with minimal work and investment you'll have a machine to enjoy. you can't beat the price. good luck , fd

 

Well, that should be a cool project. Post some pics, I would like to see what a $20.00 looks like.

 

As with any engine post the casting numbers.
All of them from the:

Block
Heads
Intake

 

Ford casting numberson the FE don't mean squat. Trust me on this. Try a search on the FE forum and this topic is amply covered. The short of it is this: Using the "dowel" method check your stroke...if it measures 4" its your 428, or possibly a 410. 3.75" is a 390. This is the only accurate method without dropping the pan and id'ing the crank. 90% of the time you'll have a 360 but maybe you'll be one of the lucky ones.

 

are 390's rare?

 

No 390's are not rare overall. But most trucks came with 360's, so consider yourself lucky if you already have a 390.
