It looks like I'm not too far out in left field then, as that is around what I expected to need, and given the air flow demand I expect the turbo to have some lag down low. I'm going to try and get a twin scroll turbo and if I do it will be plumbed in as such.

Ultimate goal is the drag strip, and it will be an automatic transmission. I have to go get the cam card for the duration and LSA numbers, but the lift is .460" and I expect my good head to flow around 220-230cfm at that lift. My current head is "probably" around 200cfm, but unless measured its just speculation. The tapered port tunnel ram intake ought to help as well.
