gretchen/jason Posted November 19, 2006 Share Posted November 19, 2006 I had a set of SBC 350 heads ported and such 3 angle valve job the exhaust valve for instance is what im concerned about as im running a super charger and the intake is of little concern So id like to ask how much will i notice the port job the cfm flow on a bench flow machine took a 1.5 exhaust valve the first test showed 185 cfm with a 490 lift i believe it was measured in inches of mercury to acomidate the high altitude where i live . So after some grinding it went from the above stated flow 185 cfm to 235 cfm with the same 490 lift i assume its alot even though the numbers dont seem to different any remarks are welcome Quote Link to comment Share on other sites More sharing options...
