A stock 5.3 with 6.0 heads will not get 8.5:1 compression. It will only drop to around 9.2 to 9.5:1

Who makes this GT3 cam? I have never heard of this. I don't remember any company naming their cam this. If they did it must have been a long time ago.

An inline blow off valve now thats funny. Is it an inline 4 or 6? I prefer v8's myself.

Dude, you sound like you watched the fast and furious. Do a little research and get back with us. Just to give you an idea a stock 5.3 can make 500rwhp on pump gas

A 5.3 with 6.0 heads and a turbo will yield 598 wrhp every time. Everyone knows that
