Fordwiser Gearhead Posts: 390 From: Metamora, Illinois Registered: Dec 2000	posted 03-31-2003 12:21 AM While having my heads off for a freshen up, had my buddy get some numbers for me on his new flow bench. These are 4V closed chamber with Price Motorsport high port plates on the exhaust side. Porting was mostly done by me, with some pointers and fine tuning done by my buddy, nothing real exotic (except for the plates) mostly just smoothing and blending. Tested @28" lift=intake/exhaust .200=145.6/105.8 .300=216.2/141.2 .400=268.2/180.8 .500=287.6/204 .600=301.2/223.4 .700=312.8/230.8 Roger IP: Logged
