Geez! I just looked up and saw that the 370cfm was at .800 lift!
I'm pretty sure the prc's make that at like .650 lift.
prc 361@.700

^^Here we go again. Who cares so much about 6 to 10 cfm differences on flow numbers. It's what it will put out as a whole COMBO. And this COMBO right here makes POWER!

They go that high on lift to show it's a stable increase in flow. I seen some in higher lift start get real erratic which is a turblent port. These dart heads are solid!

Who is doing the CNC work? Your buddy? We're going to have basically the same heads. Mine come in at 223cc from Advanced Induction.

Incorrect. You're looking at the ported stock LS3 heads. I looked it up and the PRC 260cc AFTERMARKET heads flow 372@ .650 & 380@ .700. http://texas-speed.com/p-4010-prc-ls...der-heads.aspx

Flow numbers don't always tell the whole story.

Good power but not an ls3 a 7.2 liter is a full liter larger block definitely was ready to see an ls3 in the 7 hundreds.

Good power producing heads do like to see a test with the MSD air force ls3 intake and perhaps the rest of the dyno sheet will then be reveal?

By all means keep the tests results coming thanks for letting us in on your tests.

Wholeheartedly agree......

As an aside, if one was to compare flow numbers the minimum requirement would be to do so on the same flow bench.
