Hello (BTW...what's your first name?), The Stage 2 SE's I received from AM&P with 2.160"I (stock Stage size 2.125" w/ 3/8" stem) & 1.755E (stock size but w/ 3/8"stem also) both with 11/32" stems, no porting or blending what-so-ever (all rough machined cuts present) with competition 3-angle valve job and back-cut valves. Flowed on a SuperFlow SF600 flowbench @28"H2O, 72*F, about 40% humidity and barometer right at 29.8"Hg. .100....72.2 .200....148.9 .300....217.8 .350....247.1 .400....272.6 .450....290.8 .500....298.1 .550....292.8 .600....295.2 .650....297.9 .700....300.0 .750....301.3 valve held wide-open....305.1 You may also want to read this thread also as it goes into a little more detail.... http://www.v8buick.com/showthread.php?t=84145 :TU: Hope this helps...
Thanks Kerry I believe my buddy ordered them with the additional 250.00 bowl work. what did your exhaust flow when you got it? Bob
Hi Bob, I've yet do any work on the exhaust ports but I have flow them as received from AM&P. My notebook with my flow numbers and notes are at my buddy's shop. I'll get them tomorrow and post for you. As a side note....Yesterday (Sunday afternoon) I flowed both an intake and exhaust on my Stage 1 SE I did awhile back to compare with my Stage 2 SE. I had done that entire exhaust port with chamber unshrouding and peaked at 263cfm without a pipe! at I believe .700" lift...but again...my notes are not in front of me. My Stage 1 SE's have the same 2.160"I and 1.755E 11/32's stem valves. The intake has low-lift numbers 10-15cfm better due to unshrouding in the chamber than my Stage 2 SE's but have the turbulence starting at .565" due to the short-side not being laid back near enough. The Stage 1 & Stage 2 both being SE's have identical intake ports and all so I'm able to compare, find and measure the differences in each I've done to find both the strong and weak areas in both.:TU: More to come....
