LS7 heads vs aftermarket
LS7 heads vs aftermarket hey guys i was wondering which flowed better & which would be better for an LS3 427 stroker build. heard the LS7 heads were awsome on the ZO6 & wasnt worth replacing & wondered if they would fit on the LS3 427 shortblock like Texas Speed & Scoggin Dickey sell. would a cam made for an LS7 work in that engine also? what about intake would i need an LS7 intake to match up to the LS7 heads ? are AFR & TFS heads better than LS7 heads?

The aftermarket ls7 heads offer more strength and also thicker decks and fitment to smaller bore sizes,comes in different port and chamber volumes and 4 and 6 bolt as options-
Intake will need to be a ls7 style one wether its gm or aftermarket ls7 casting head--
factory ls7 heads will not fit an ls3 427 bore.you need atleast a 4.100 bore for those heads to fit.The only ls7 head that will fit is the Mast 4.00 bore ls7 heads with the smaller valves.
i want the ls7 punisher or lethal cam from ragin racin its a 660 lift @ 113 lsa i see i see alot of the people with ls3 427 strokers & the arent making the power that an ls7 427 does in the z06. why not? i see cammed with heads intake & exhaust z06s put down 570-585rwhp but the same setup in trans am & camaros on the ls3 427 is only 520-540 why?

John i am lost
when you mean ls3 strokers are you saying a 427 deal with a 4.1 crank or a 414 4.070 4 inch stoke for argument sake etc etc
i have seen otherwise with a 4 inch stroke
Happy to be educated if i am wrong-
