383 Stroker

I would like to turn my TPI into a 383 stroker with an after market intake manifold/plenum. Anybody have recommendations on kits, intakes manifolds, heads, cam, pistons, etc. I'll be using the car to race in SCCA. Thanks.

It's mind over matter. I don't mind because you don't matter.

If your doing the 383 you'll be in Mod class.
At that point why worry?
