want to make 400 whp with 6.0
#24
another question can 243 heads make 400 whp stock, with a 224 cam, I'm pretty sure i'm doing work because I'm pulling the heads anyway but i was thinking of trying them with just a fresh valve job but i don't want to put this thing together and be disapointed, i thought the 317 heads flow as good as the 243 but with larger combustion chamber but now i'm not so sure what are you guys making with stock 243 heads

I think you come very very close to 400 hp with stock 243s.Depending on the dyno!
My buddy has a lq4 with 317s and a tr224 in a 4x4 he made 365 at FMS
A few LS1 with full bolt-ons and a tr224 have made 400 hp before
Also the 243s flow roughly 20 cfm more on intake and roughly 10 cfm more on exhaust.
Plus the bump in compression
