427-593 rwhp
the SBC has had 56 years to be perfected and it shows. i think the biggest issue with the LS series has been the oiling system. each platform has their huge advantages and disadvantages. with the addition o a platform that now mixes the 2... we will se some really wicked combinations. an SBC 406 bottom with an LS7 top end is now a possibility.

Brian, Andy did some custom twin cut-outs on the car right at the collector. Drivetrain is fairly simple, centerforce with a Moser 12 bolt. I called Andy and he's going to post the results, it's a Dynojet. Heads, well what do you say, I would not run the L92's again, they need to much work for what I wanted. Best CC to Flow from what I have seen without reworking them are the Trick Flows. The Trick Flows have a very nice port design that if you look down the intake port you can basicly see a straight line to the valve, this is a good thing. Turbulence is HUGE in heads and remember if you speed up air the straighter the line to the valve less chance of turbulence. I built a car for a guy with these heads and the power is awesome. A stock L9-2 head has too lazy of a port design unless you have HUGE cubic inches or a blower. We did make 648 engine dyno Hp. with 98 LS heads with lots of work done to them.
When Andy had my car out there for the tune and dyno run he seen how I had mine rigged up and gave me a call to talk about it for this setup. I got a call with a good chuckle about how much horse I was loosing at the wheel with my exhaust closed. Don't even ask how much either...................nobody would believe it!?!
