Well I got rid of the ol 5.3 with a hot cam, on dyno day it put down 300rwhp and 360 on the 100 shot. It's got 4.11s, 3500 edge stall and it did have shorty headers. The new set up is an lq9 with ported 853's flowing about 300, compression is 11:7 with a Texas speed 228/228 cam, pacesetter LTs, with the while arp bolt kit. I will be running a 150 shot on slicks. The motor came out of a camaro that put down 605 to the ground on a 150 shot and ran a 9.52 1/4. I am having Glenn here in Oklahoma tune it this month and I was just curious to see what yall think it will run?
