On an engine like that, you're lacking a tune, and cam selection plays a large role in powerband.

I wouldn't push the stock block any further, your not doing bad considering what you have to work with, is it intercooled???

Wow low 10s on the stock block. Do you have many passes on this set-up?

About 5 pases total. I had this engine and trany ( C 4 ) on a full body, best pass: 10.28 @ 132 MPH, 1.31 on 60 feet. Now the set up is on a half chasis, about 500 lb less, I think something was lost when I swapped bodies. Now I have 14 in Tires, 9 in rear.
I don't have an intercooler. The only think that I've added was a Computer chip to delete RPM limmiter on the a stock Computer, it was cutting off @ 6400.
