HR LS2 402 C6 Corvette 560rwhp 504rwtq We just finished up Jeffs (the owner of the shop) 2005 C6 Corvette. We were pretty happy with the results and I believe they speak for themselves. Look how consistant this thing is!!
All runs were done with all the belts on, 30psi in the stock sized Nitto Invos, and air filter in. Just as it was driven on the street. These numbers were made on 93 pump gas.
First time at the track we ran 10.38 @ 136.
Here is a run down of the build.

I just put the GZ vaccum pump on my Silverado 402...those are great guys to work with. I didn't have a direct fit so they sent me xtra parts a couple times. I saw some power under the curve on the dyno. Ran it last night in Gainesville...worked flawlessly !!!

10.30s with a mid 1.50 60' at 136mph! We have a little suspension work to do, but the mph is promising. I would like to see it on down in the low 1.4s. BTW car weighed 3360 or there abouts with Jeff driving.
