I just bought a property and found this 1975 f350 and was wondering what engine it had in it.
These trucks are way before my time as I have only ever dealt with 302 engines from the obs era.

 

Assuming it has the same engine, or at least same size that it came with after almost 50 years - may have a look at one of the VIN decoders online, one of which is - 1973-1979 Ford Truck 11-Digit VIN Decoder - Blue Oval Trucks

 

302w if the water pump bolt is close to the top of the block- bottom surface of the head.

 

double post

 

Ac3jpb70467 is the vin i think

 

Not sure that's the correct VIN given the decoder site linked above, but if so, the 4th digit being the engine code 'J' lines up with a 460 4bbl.

Probably reasonable with the 1-ton F350, but just doesn't look physically big enough in the pic also doesn't look like a 4bbl carb either.

 

carb was taken off that isnt the og one

 

and it is I posted the tag they painted over in another post thats the vin im pretty sure cant tell because they painted over it though

 

Eh, no idea here, may have to resort to busting out a tape measure and looking at the physical dimensions posted by sites such as - Ford V8 Engine Identification - FORDification.com
