Run a search for Sinister Chevelle.. After the 5.3, he had 70's on a 6.0.
I think he got down to a 6.0? Something 1/8 mile at 3800 pounds.

That chevelle moves out pretty good. What size a/r for a street car .68 or 1.0?

Kind of limited on space, and I would prefer a small frame turbo.

What kind of power do you want?

I believe all the on3 small frame stuff runs the 65mm P-trim exh wheel. These are available with a 66mm comp wheel I hear if you call and order it. Most aren't going to max out 70's on an SBE build and the 66s have a better exh to comp wheel ratio.

I also like the idea of the holset HX35/40 clones. They have internal wastegates and would make plumbing and overall costs lower.

They have the larger 87/78 exh wheels as well...
