What's the opinions out there for swapping 351w from 1980 F250 into my 1979 F250 w/ 300-6. Both have fourspeeds, both 4x4.
Not sure what tranny is in 1980 but my 1979 has np435. Did they Still use np205 Xcase in 1980? Anything else worth taking from the 1980 to the 1979? Any opinions or ideas are helpful.
Thanks

 

Go for it. Use engine mounts and perches from a 302 truck to fit up the 351. You might need to change the rad to get the inlet/outlet on the right sides.

1979 F150 Custom: nothing under the hood at all (again)
1987 F150 XLT Lariat: 88 351W EFI
75 351W: soon to have 91 heads, ?? cam, double roller timing chain, Edelbrock Performer intake & Holley carb and be put back in 79 F150
84 351W: waiting for ???
Chevy 454: waiting for a truck (Mazda?Nissan?)
