(pics added) by cuisinartvette on 2008/11/25 2:44:07 interesting, valve job was finished off tonight Had this guy flow them for the hell of it and as expected the numbers were low. I have flowed: LT1 L98 Vortec AFR 185, 210 with porting On this bench and then gone directly to AFR where the exausts are about the same yet the intake readings are higher. I confronted the machinist about this as I was getting tired of spending money out of my pocket as I knew these flowed more and explained if someones spending damn good money on grinding they want to see good numbers to or my name is mud. The machinist told me he knows his bench (both use superflow 600s) reads low as he doesnt care about true readings, they only throw them on there to check gains so whatever the difference is (before and after) it is. Most heads they bring in are 18 deg or Reher-Morrison and not much is done to them. I asked him if they would look better with wet flow, lol. My suspicion was the setup on the intake meaning the fit and claying in of the inlet fixture to mimic a perfect port match, thus the true readings on the intake are way off. Noticed the exausts are similar, to be expected. I will have a flow sheet tomorrow on these but for the time being the exhausts on these 113s heads are over 200 cfm with no pipe. THink the owner should be real happy, first cut went 181 and he was content with that . This is with a stock valve size. I did cheat a little and do a little unshrouding on the combustion chamber. There is more to be had but the 2nd cutting on these is all charity on my end and he wants to put it together now. Cant wait to hear hios impressions of how it runs. So far real pleased. :occasion7:  :occasion1: Taken about a month or so ago prior to cleanup, valve job, etc. [IMG]http://img.photobucket.com/albums/v224/kalthoff1/139_39191daum2.jpg[/IMG] |
