Finally a real test of the singleplane from GMPP.Was wondering if you saw this yet?Made almost identical hp as ls6,this was with a 750 Mighty Demon 750 carb,with1 3\4 Hooker LT and hotcam and ls6 blue springs it made 503 fwhp, stock with headers was 429 hp.The MSD ingnition system looks pretty cool!!I"ve heard that the hotcam is not all that great is that true???

It seems like a nice piece for someone not wanting to use fuel injection, but the dyno charts before and after arent a good comparison since they had valve float in both and then fixed it for the carb only. Also from the article, I assumed this was against an ls1 intake, so the gains weren't that great.
