Get it...its worth it even if you don't use it yourself. The gt40 heads on a 351 will work but they are not optimal for power.

However, the 351 will make more torque than a 302....and it'll handle power added a bunch more.

You want a roller block casting 4fte...since you've got to strip it you can identify it by the spider lifter brace in the valley under the intake. I think the 351 went roller in the early 90s ( could be wrong )

To put it in the mustang it'll need a swap oil pan, accessory brackets, headers, and lower intake.

It is worth it. Just do your research. There is quite a bit involved. Hood clearance is a definite issue. I had to buy a lot of parts for my conversion. Accessory brackets, headers, distributor, flywheel, oil pan, distributor gear for roller cam, serpentine belt. I’m sure there is more that I am missing. Intake! That’s a big one!
