You wanted honesty. 70gtx will probably trip the scales at about 3800.

From a dead stop I'd say no, since the wheels have to get the weight moving, and more weight is harder to move. From a roll it probably would be harder to break em loose with more weight though. Not sure....

My linkage is somehow ferked up. I can only get it in PRND. No drive 1 or 2. The reason is long story. But I have a floor shifter and console to install so all that will be corrected. So only being able to put into regular drive hinders me being able to spin out?

What is this "high-rpm lifter crash" of which you speak? It means that Comp Xtreme hydraulic cams have overly-aggressive closing ramps which limit their RPM potential to well below what smoother hydraulic profiles are capable of. It's not just a "Mopar thing" either. I've seen SBC and Pontiac tests w/ those series of cams where the valve train starts to go bonkers anywhere from 5000 RPM on up.
