Wise, those intake numbers are almost a mirror image of my 440-1s!! Very good flow numbers for sure. R&J that did mine are among the best in the business , so from my point of veiw, you have a dynomite set of heads there. My runners are 365cc, so you have more velocity for a bit wider powerband?
The only differance in flow numbers came above about .500 on the indys, they keep on climbing to 301 cfm at .800. But that may very well be useless, with most everything happening in the midrange lifts anyway. I will be looking for a dyno post in the near future!!
