Just did a set of heads and cam on my brothers 383. He bought the motor from a friend of ours and we ran it on the duno and it made a best of 534 with q16 at 6500. We pulled it apart cause he wasnt happy and it was supposed to be a roller but it was a flat tappet and it had a set of bowtie phase 6 heads on it with quite a bit of work done to them. Its a 383 sbc with about 14to1. So I put a set of AFR 235 eliminators on it, a 701/701 roller with i think it was 284/286 installed at 104. 950 hp carb with a bowtie intake. Looking for at least 650hp out of it. What do you guys think? Hoping to put his 3200 lb camaro low 10's with this using a glide and a 5000 stall converter with 4: 56 gear.
