6.0/LQ4 carb torque curve?
I'm planning on putting a 6.0 LQ4 into a 68 vette. It has a 3.08 rear end. I would also like to add a tremec OD 5 speed trans (0.68). That would put me at just under 2000rpm at 75mph.
I think the fuel injected lq4 could probably pull that rpm in a vette without lugging, but what about the carb version? I dont think the injected lq4 intake will fit under my hood, so I'll run the carb/dual plane manifold setup.
Also considering I'll be running Vintage Air with this.
Opinions? Will I need to change to a 3.36 or higher rear end ratio?

I'm going with the GM Performance four barrel single plane manifold for my LQ9, I'm using a F.A.S.T. 90mm TB adapted to a 1" spacer so it will sit more or less like a carb. I'll be using a little bigger injectors and my existing LS1 computer. I think it will run ok.
