I don't think it's impossible just not streetable or inexpensive. My 380 does 550hp but is a 48* W-2 mini stroker that runs on 110. Much easier to follow Mr P's idea on a 416 that runs on 87. You'll be happier in the long run.
I will already have the block and crank, can use shelf diamond pistons and probably like a scat H beam rod. Won't be real expensive at all. Lots of stuff I already have.
Don't really care about having to maybe mix 110. It's 6.99 a gallon here, and it's not like I have the time to log a ton of miles on the street. So even if it costs me 300 extra a summer for fuel( unlikely) that isn't enough of a negative to matter to me. Don't think it needs to be radical to run 10's even in a 3400 pound car. Just need good heads.
Hmmm. True. Do you think W-9s would be feasible? Not sure but they might flow in the 300s with mild cleanup. Course that makes acces. parts more exotic. I'm just not well versed in other heads. I like my W-2s.
Those cnc pro comps like bondo has went high 280's on a reputable bench. He built a 60 over 340 with 4 inch crank at 9.5 compression and has already been 10.57 in his bench seat swinger. I figure his crank is probably 3 tenths better than similar build stock stroke. But I would have well more than 9.5 compression. Think a head like that
will sneak into the 10's with stock stroke. Without working up a ton of sweat and be very street able.
