shadowsniper3006 Posted August 5, 2009 Report Share Posted August 5, 2009 Hey Frank, do you know how the exhaust was tested, 4.0 bore, pipe size? Bump for a great guy! Brad Quote Link to comment Share on other sites More sharing options...
RevolutionRaceWorks Posted August 5, 2009 Author Report Share Posted August 5, 2009 Hey Frank, do you know how the exhaust was tested, 4.0 bore, pipe size? Bump for a great guy! Brad Thanks Brad. I did some homework on these. The advertised numbers are flowed on a 4030 bore at 28" wc without a pipe From what I have been told they are conservative to say the least. I tell ya side by side with my 2000$ WCCH heads they look damn close diameter of the ports and quality of work. The only plans I had for these if I ran up heavy lift I was going to use patriot golds but.. I like the l92's with less cam. My 408 makes monster torque but the HP flattens out with my big cam. I plan on swapping to less lift and a little less duration and a tighter seperation to give it better street manners. Right now It sounds like a nascar at wide open though it's 4" corsa and 1 7/8" headers And the idle is enough to make a real 454 ls6 cry all on E85 Quote Link to comment Share on other sites More sharing options...

DetJoe did an excellent write up on a swap he did. Check out his posts it's an excellent swap to do. No machine work has to be done if that's what your asking.
