So there has been some talk about these heads. These are the First ones I have used. The reason was to get as much air flow and port volume for what we wanted to do. The goal was to make as much power as early as possible. I think we got what we wanted, but without a back to back test its hard to tell if these heads were worth it or not.
Anyhow, here is the combo
360 stroked and poked to 416
Flat top pistons 10.8 to 1
BM heads
MRL/BAM offset roller lifters
RPM dual plane intake
FiTech EFI
MRL solid roller cam 281/285 duration(seat to seat) .620 lift
Milodon gear drive
Well, you get the idea. Torque is what we wanted. Did we get some? Ummm........... Yeah we did.
525tq at 3100rpm, yes 3100rpm. Damn. Peaked with 582tq at 4350rpm. Still making 550tq at 5500rpm.
It also made 584HP at 5800rpm. Fuel pressure was dropping as I had the pump hooked up wrong, didnt figure it out until later. Might make closer to 600hp with the right fuel pressure.
All this on pump gas, and a nice idle. It pulled 14in vacuum at 950rpm idle. 1.40 hp per ci, not to bad for a Pump gas street engine.
