Default 302 to 351
I have a 94 f150 with a 302 and auto trans. What will it take to put a 351 in it? Computer? Throttle linkage? Etc....

Basically, the engine. You have MAF so you want to keep your computer and wiring.

Soo, I'm looking at doing the same.. Will you have to change the PCM? Also is the wire harness the same?

Sean already answered that question in his post...

wiring harness is different from Speed Density (MAP) to Sequential (MAF)

Forgot to mention oil pan as well, just did the 302-351 swap myself, so if you have any questions, I could probably answer them
