hmm, this kind of worries me as ill be running the same pulley setup. are you running a whipple 2.75 or a RR 2.75? i also have the thump rrr (w/ grooved pulley).
my setup is very similar except my boss block is stroked to 322, 9:1 comp, stg3 livernois heads, oversized valves, custom cams from J. Mihovetz, ported 2.9 whipple standard (non-crusher) inlet, ported BF tb, ported lower intake, 1 3/4 ARH & 3 inch o/r x, e85, etc etc etc...
im shooting for 23/24lbs but now im thinking i will only see around 21psi like you did.

I am running rr 2.75 pulley. The reason I had really bad slippage was due to belt being too long. I just ordered smaller belt which should fix the issue. I might install custom cams and bigger headers. Before Bob Kurgan comes out here again and get it retuned.

The quest for more power never ends. Bigger cams and longtubes will help your setup tremendously.
im glad to hear it was just a belt problem. What size belt were you running and how much smaller are you going to go?
Thanks!

You are right on point with that, Hp is like a drug once you are hooked you want more and more lol. Bob said with bigger headers the car should make another +,- 20hp. cams should net me another 30-40hp. The belt I am running right now is 77 3/4 inches I just ordered 77" belt. Going to try to see if it will fit..
