TrickFlow heads. Houston we have a problem.
I mounted up one of my small block TrickFlow heads today so I could flow test the M1 before I send it back and to get before and after numbers on the RPM intake and Victor340 intakes. I only flowed I think one port on these heads then I welded the one up and moved the pushrod hole over. Then I grabbed the other head and screwed up the seat trying to cut it for 2.08 valves. Every other port on that head was untouched so that was to be my test head. I posted up the numbers last year on the other head in our flow chart post. Well imagine my surprise just now when at .600 I started to hear turbulence. At 625 lift my depression meter went nuts and flow fell rapidly. I’m going to try the other two ports and hopefully have a good one to test these manifolds on. When I went to check airspeed at .600 it almost ripped the probe out of my hand trying to get to the center of the shortside. Meter pegged at 401 FPS
