Disappointing #'s?

welllllll.... allls i know is my 74 duster 440 that is

.030 over
10.5 to 1 compression
magnum cam grind something like .458 lift .268 duration? whatever a 383 roadrunner was
stealth aluminum heads
schumacher tri y's
pertronix style dist. w/ blaster 2 coil
3.55 gear
727 w/ 3000 stall
28x10 slicks

ran a 12.66 @ 105 mph and a real low 8 in the 1/8th

i think my car would be realll close to 3600 with me in it aswell.

i would say your numbers look pretty good. good combo also

the robinette hp calculator said i was making 350 RWHP and 410 @ the flywheel.
