Well It Finally Happened

Yes you did LOL. He is going NA.

OP, look at Edelbrock performer RPM heads to see what flows will easily get you to 400 HP. So your needed flows will be above that. Camming up to get the cam to flow to match that larger head flow will be needed, so but you sounds like you don't mind an engine that is a bit rough at lower RPM's so that is all good.

Personally, I see only limited cases to put on a blower with 10:1 SCR and put in a lot of cam overlap. I bet it would just push the lower end of usable RPM range up, and make it a peaky, high RPM only engine and blow a lot of fuel out the exhaust at low RPM's. Might make sense for an all out drag racer and a big blower. This all relates back to the comments in post #50.

I run a good solid 10:1(and change) with iron heads on 85 and have no problems. I'd like to hear some real numbers fro the guys at lower elevations. I'm at 5k feet and have never had so much as a knock or ping.

FWIW, I have run 10+ on iron heads and with 87 had knocking at elevations typically in the 1000-2000 ft range. And I could not put all the timing advance in that some would like to do, even on 93. DCR was around 8.4. So your cam may be large enough to lower your DCR too, even at sea level.
