sorry..i was talking bhp...and i figure that many of the other guys are too...
so you cant get 500 whp out of an LS1 with a full NA build?

 

I am sure you "can"........ but it would be a pretty special car to be doing that with 350 cubes.
MTI, LPE,A & A, DTE aren't doing it.

They are getting those numbers with a 402.

Now you are REALLY into the drag racing scene, so maybe you would be using a MUCH more agressive cam, then is used for a DD.
