you do know that Pontiac has not made a brand specific engine in like 20 years now. ( maybe longer) gm uses the Chevy engines across the board now.

them north star engines are in Oldsmobile cars and caddys too. my brothers got a aurora with a north * and the 4t60 trans iirc, it chirps second gear lol id say it feels as fast as my regal gs, both are stock.
