Message: [QUOTE="hucorey, post: 1542091, member: 13749"] I figured I'd fill anyone interested in on a big project I've been working on and have finally got these custom ported and polished 7.3L heads over to a friend's to have them flowed. Using a Superflow SF300 flow bench set at 28"w.c., with a stock cam profile intake lift, these showed a 44cfm increase, and with a .550 lift, the flowed 54cfm more than the stock heads. Stock heads were tapped out on flow at 132cfm regardless of cam intake lift, so this tells us why it's so easy to hit fairly high boost numbers because of the stock intake runner being so restrictive. Next is to get some more base line Dyno results from the shop truck and then swap these heads on a see what kind of improvements we get. I need to get my 230/100 injectors freshened up before I get the heads on too before I hit the dyno. I've got a couple that are missing when it's cold. So the set up is going to be my shop truck. 230/100 injectors KC38R turbo (has the s300 turbine wheel) ******** stage1 cam Comp Cams 910 springs shimmed to 125-130 seat pressure Manton series 3 .095 wall pushrods AirDog II 4G fuel pump CNC Fab fuel system Older Stealth SRP 1.1 HPOP Yes I build hoops, but this testing is irrelevant on brand of HPOP.
