I just got my hot rod mag. To make a long story short....
HR took a new LS7, installed a hot cam and made 600hp at 6800 rpm and 526 lb-ft of torque at 4800 rpm.
This was with headers on a engine dyno. It says, The stage 3 cam made 90hp gain over the stock cam with the same headers. WOW. Thats just cam and exhaust , wait till the big mods start.
Check this out... GMPP dealers already sell a carb intake for the LS7 and L92 6.2L.
The results w/ the open-plenum singel-plane carburated intake manifold's running a 1,050 cfm race demon carb. were near-perfect overlays of the EFI manifolds HP TQ curves.
Just a little info.
