Actually, the ram air hood is what GM claimed to be giving the SS the extra hp over the Z28. Because there was no other engine changes between the two.
Ran a 12.88 in my SS
Ran a 12.74 in my Z28
Only difference...Loudmouth exhaust on my Z28 vs. the SLP Dual/dual exhaust on my SS. The weather conditions were the same, the track conditions the same, and it was even at the same track. The Z28 was consistently running quicker times....I don't know...weird.
But, all I'm saying is that they should have left the same cam in the SS instead of using a smaller one for the production SS.
