Can I interchange a recently rebuilt 1982 351w block (propane/hardened valves/RV Cam) into my 1994 E350 (will the intake/exhaust/tranny bolt in the same?
Thanks

 

There is only one 351/5.8 block and it's tranny bolt pattern has always been the same. The heads got a lot of changes over the years but those too have been unchanged in terms of intake bolt patterns from 1978 on. The only issue you will have will be with the cam, if it's a carb based RV cam it won't be compatable with the EFI system, you'll need to change it to one that is. The Crane 444232 is a good choice, but there are others as well.

 

Thanks Conanski, helped clarifying a few things especially cam.

I always thought that ford made 77-93 then 94-on 351w block.
specially concerned about fuel injection intake issue.

Thanks again

 

The blocks were modified to accept the factory roller cam in '94, but externally nothing changed.

 

your asking for trouble converting to efi i have seen so many fail and go back to carb which is better anyway
