Victor Jr EFI Intake
I have a somewhat similar setup where i have a 227/231 @ 0.050 Hyd Roller with .530 lift on a 110 LSA with the Edelbrock Super Victor EFI and megasquirt on a 9.75:1 340. I also have a T56 Magnum 6-speed, and I can drive it at 1400 rpm and still accellerate, but not fast. Mine will do an absolute smoke show from a 5mph roll, let alone if you rev it up before popping the clutch. Before I did the 6-speed swap I had run this car with an A-833, Air Gap and 750 Annular DP, and this runs better even at low RPM.
My car has 22 degrees of timing up front and is at 35 at 2500 rpm. I would try more initial timing if you aren't getting ping.
