I have 2009 L92 out of a Denali in my 73 Camaro. Stock L92 with Texas Speed cam 225 Intake .050. Made 420 at the rear wheels. Thats about 495 at the crank. Just a bit of a chop at idle. Has enough vacuum for power brakes. Had to upgrade the push rods and springs.
I wasn't looking for huge power just a mild upgrade from stock.
