First off, these motors are aluminum head engines. I have seen more than one of these LS1's with 9psi on stock internals. Its all in the tuning man. It CAN be done. Both of them are dail drivers, and one has had the whizzer on for a year and a half.

As far as the LT1 vs/ the LS1........the LT1 has a mean TQ curve way down low. I peaked out at 311 rwtq at 2050 rpm. The LS1 has a gradual increase. Plus the LS1 makes it power on the top. It redlines in the 6200 rom range stock, as to where the LT1 is at 5750.

I am speaking from first hand experience here.

Where did someone get 500 horse on a stock 4.6?

Link me please.
