i dont think its a 347, just by comparing his and yours, they look the same...

ill get some better pic's in the morning


dyno would be a quick answer, only like $90


with nice heads like that, even a cam, best he's gonna do with a 302 is prob 270-300hp depending on what hes got.

but if hes at 320-350+hp should be a 347.

(idk, to me i think youd be able to tell by the 'ol butt dyno)




im putting my car back together in the morning, so ill take a quick picture for you.

that won't tell you anything anyway!!^^^^^^^^^cause a 302/306 would have a .030 overbore as well does a 347, to be sure you'd need to pull the pan and see if piston skirts are notched, and any quality 347 piston isn't gonna be 4 valve relief it'll be 2 with clearance for a 2.02 valve, Imo you most likely don't have a 347 sitting there but pull the pan and check
