typical 6.0, Ls3 heads Fti cam, vic jr with 950 ultra hp carb now. Talked with Mike Lough, he said My carb is choking it. Says I need at least a 1050 dominator. BUT......Lots of options. 2 circuit? 3 circuit? annular boosters or down leg? This is just a all out max effort 6.0. Trying to get all I can. Best its went so far is 6.307 @107. I knew you could steer me right.
