thanks. Its a 455 .035 over with a 4.25 stroke crank.
The cam is .630 lift and .266 - .272 at .050. The cam does not require a lifter bore brace. I wish my 60's were better, im only getting 1.52 to 1.54 and its really not spinning. Its a 10 inch 4400 ati which will work really good when I spray it, but on the motor it might need a tight 9 or 8 inch. What kind of setup does your brother run? Thats the e.t. im shooting for and I think I can get it with the rpm intake. I probably should have went up in jet sizes that nite and bumped the timing up to 34 or 35 degrees but the track was to crowded and didnt feel like messing with it since it was the first 3 runs on the motor. How much does your brothers car weigh?
