With the 2.02 valve, I think they flowed 300 cfm at .600 and like 305 at .650. Not sure. They are not a full race port. They were ported nicely, with alot of detail work but not a huge port, I think avg. csa was 2.5" ish.
I just made 620HP on 10.9:1 with a 4" crank and heads that flow over 300cfm but only accessed 280's.
There's alot more to "accessing" flow than just cam, compression and flow. The whole engine and it's components must work together in the same basic rpm range or you'll leave power on the table.

Kenny, an Indy intake with my cnc 4500 opening and a 1050 dominator would be worth around 30-40 HP on that engine!
I'm very interested in the outcome of your project!! At least your having fun with it!!!!

Yes indeed.

I know, you dont seem snappy at all, we're just bouncing it back and forth for the sake of insight and a multi angled view....and hey...we take this stuff seriously :salut:

You're right about liquid/air density in a cycling engine, then figure the heat mixed in.
As for the csa, yep..that would effect the rpm capabilty and yeah if the cam was bigger than sht...it would be a bad combo that would be shorting itself on a lot of power, let alone usable power.lol

I dig what yer doing though.:thumrigh:
