Wow got the 5.7 installed!!!
I finally got my 5.7 installed in my 02 sierra. I was inpressed with the 4.8 with about 11 psi behind it but this thing was only makin 7 psi and was way faster than the 4.8. 
There are two places you can tell a big diffence from a dead stop and hittin it from about any cruzin speed. I know my 4.8 was fast once you got the rpms up but when it changed gears it was like never ending boost lag. The 5.7 just pulls hard all the way threw. I got to tell you allen knows what he's doin because I told him that I was puttin the 5.7 and 4l80e in my truck and he hit both right on the dot not only does it run fast but it shifts great to.

-uyh8[QUOTE=sfj]hell all i need to know is 5.7 blower motor 
works for me man although i have to agree more details would be nice 
[/QUOTE
Yeah i guess i could have listed alittle more. Well were do i start. I have a 5.7 out of a 02 corvette. I built the motor and put diamond pistons 8.5/1 compression ratio callies connecting rods h beam. The heads have been ported and polished they have bigger valves 2.02 and 1.57. im using a lunati camshaft with like 221 221 duration and 558/558 lift. The supercharger i am using is a whipple supercharger with a 3.5 inch pulley which makes 8 psi on my motor. I want to turn the boost up to about 13psi and hoping to do that on pump gas. Allen done my tune and it turned out great. Allen is going to add more timing to it because of my low compression which is good. That is about it for my motor. I know my best with the 4.8 was like 13.4 @102 and i hope to get in the low 12s with the 5.7.
