built a 10.5:1 383. cam is 232 dur @ 50 .485 lift. cam is my custom cut from bullet. Thot that it would have more rumble in it but it basically sounds stock. VERY VERY SLIGHT rumble but not real noticeable. have one of my 750 holleys I built on it and a regular old edelbrock performer intake. I feel its down about 100hp. a/f ratio stioch is near 14/1 across the board, no bog off idle or anywhere else in the RPM, pulls all thru the band but doesnt feel like it pulls as hard as my old 357. you got any ideas?
