LS7 ENGINE! hands down it wins.

and for the kid saying 900hp 540 hemi they never had blown hemis in the daytona or chargers or anything from mopar back then and they wheren't 540ci the biggest was a 526 that was built for drag racing and there where only 2 built of its kind and it ran in the nhra super stock div.if u really want to get into the classic mucsle car wars i would take a 427zl1 over anything.they came from gm with a 425hp sticker on them but made over 500hp detuned from the factory and if u tuned it u where in the 800 hp range.

so to all have a nice day.
