Ron,

You you have the DP Indy numbers to post yet?

What gear are you running?

I think I'll swap on the 337 when I make the 4 speed swap, right now I like that extra torque the dual plane makes and since I'm "cube defficient" .....

The next time somebody builds one I'd like to offer up my Ported 2d to compare to a non-ported one, I think the plenum mods and opening up the throat passages to the runners out of the plenum are worth ~20hp, maybe even more on a high compression Mega-cube motor tha would push it to its limit.

With that many cubes I've got to wonder how an SR or -1 with the same intake flow/port size and the raised exhaust runner would go? It'd be a cool comparison for the EZ/non EZ debate to see what the raised port is worth in the "real world". What's got me really curious is when Dwayne flowed my Chapman head he commented that the Exhaust port was a nice shape but comparatively small, but when he put the 2" tube on it it "really took off" (~300cfm)....but more and more evidence is coming out that maybe the exhaust isn't really that critical as once thought. (smaller/faster vs larger/slower and it's effect on "keeping" useable cylinder pressure and cam selection is a topic for another thread someday) I think Indy made a great move with the EZ because most RB B and E body cars upgrading to better heads and strokers already have headers (like Ron did), not much gain (apparently) to merit having to shell out another 700 bucks for raised port headers too!
