In case you missed it I know alot of people are interested in this. The actual flow graph is on a stock lt4 vs welded/ported lt4 intake on the same set of heads. I think that a ported non welded port picked up about 10 cfm over the non ported version but SAR2K will have to confirm that for me. REad down and SAR2Ks post is where he showes the flow numbers and chart that we got from the intake.
