351c turbo questions?
So I have a 351c that's .60 over and has ported 4bbl heads with aftermarket springs, and valves in it, a eagle forged crank, h beam rods, and forged pistons in it. I have a 87 coupe I'm putting it in and wanna turbo it. So this is my question, what size turbo and what gear should I run in the rear, single, or dual, and what size cam would work the best. Any help is appreciated, thank you!

You'll find with a turbo, that the gear will be something to play with, we had 3.27 but wished i went with a 3.08. Let the gear lug the engine down to keep it in boost longer and see what traction problems you'll have.
As far as turbo, like said above, 75mm or bigger and i would go with a t6 style flange. With a 351, backpressure will become a problem. We had a t4 on a 363ci and the t6 would've been better and cheaper. Look it to the s400 (75mm) or a s480 (80mm), great turbo for the $$

You've been working on your car long enough to know that's funny now.
