I actually borrowed the BBK from him when I had my Holley apart to fix the defects it left the factory with. The BBK didn't look as nice as the Holley, but it worked as well, if not better.
Geese I wish I had that problem! 20+ #'s of boost that is!

I liked my AS&M. It looks great and performs great. I used to have a holley on my formula that worked decent as well.

What kind of heads were on Baxter's car?
Early versions of the engine used LPE LT4 CNC heads, reworked by Second Street Speed. When the 3,900# car ran 9.04 it had heavilly modified Canfield LTx heads.

I believe this may have been mentioned in a previous post, but the stock intake holes are 52mm. A 58mm TB does nothing if the downstream flow path is no bigger.

But nothing a skilled hand (Or not so skilled with enough patients/effort) couldnt accomodate for if you own a dremel and are inclined enough to take the intake off.
