Mopar purple .528 for a 383?

The 3.91s and four speed will allow you to run any intake you want.
But good points were raised about c.r. You really don't know what pistons are in it aft3r all this time.
( I think I have used five different single plane intakes vs two, whoops, one dual plane. But my cars have 3.91s and 4.10s)
Exactly, that’s why I made that clear up front. I never saw a build sheet for the rebuild, and I haven’t personally measured anything…yet. So I don’t want to pretend it’s ideal and end up with a dog.

My plan is to pull the heads when I do the cam swap and measure everything. Hopefully I’m at a true 10:1, should be a screamer for a stock stroke 383 with the .528.

Thanks for all the input fellas, it always informative knocking around my ideas with y’all.
