Nice combo's. I must have something wrong with mine.

I have a 511 with 14.3 to 1 compression. Small roller cam. .673 with 1.6 roller rockers. Basically otb 440-1 heads. 1050 ProSystems carb. Indy intake. 727 with 9" Ultimate converter. 8.75 rearend with .456's. Ladder bars. Car weighs 3000# with me in it. The best it has ran is 10.00 @ 135.26 mph. Maybe I shouldn't complain too much. The air was, and this is the best the car has seen, 6100' corrected.
I am sure that the car should run 9.60's in Vegas.

Is there something that I am missing to make it run better at that elavation? It usally runs 10 teens to 10 twenties.

Thanks.
