Hi my name is Kevin. I have been reading about the manafold. Like all of you I want the most out of my motor. I have a ls1,I bought from cbm 450hp. This is my 3rd season on the motor.I have stroke it last year,this year I put a set of cnc heads,cbm's hot cam,42 pound Injetors,92mm throttle body. I'm taken the car to cbm on friday to put on the dyno. I hope it comes together after that. Itook it out for thanksgiving and didn't feel much more power. Was thinken about a blower?
