my is not close to what you have but not that far off.
.570 .572 266 274 @ .050 106 center
418" 13.7 comp edelbrock rpm heads, Holley strip dominator intake.
850 hp carb.
4.88 with a 29.5 tire 4 speed. Car is around 3000#
best so far 10.65 @ 126
If I can get it to hook I know it has 10.50 or better.
I need to go down in gears 4.30 or 4.56 it's running out of rpm's. I'm hitting the 7000 chip way before the strip.
