For now though I am going to put the SR's back on, they are a much more street friendly package. The SR's made 764.3 ftlbs@3527rpm at the start of the pull. From 4100 to 5500 rpm they made 800 ftlbs. + Peaking at 4818rpm producing 818.4ftlbs.

We will flow test them, then put the engine on the Dino and see what we have. Port velocity is more important on this STREET car as it spends most of it’s time cruising at 2,500-3,000 rpm. I will post results in a few weeks.
