converting to carbaurator

Have a 302 in my 87 F150 now - Have a 90 something 351 windsor in my garage - Want to convert the 351 to a carbaurated engine -
dont think a 302 maniffold will work on a 351 .Is that correct ? I think I need the dizzy , wiring harness, -
Have any of you done this or is there a link you can direct me to
Thanks Will

No, it will not. The Deck height on the 302 and the 351W are different, which makes the intake manifold for a 351W wider than the 302.

You are correct. The 351W deck height is taller than the 302, which makes the distance between the heads is wider.

No, keep the harness that is currently in the truck.

What he said. A “ ‘90 something” 351 would be fuel injected from a truck so you have all the parts? Why not just swap the 351 for the 302 and be done with it?
