Do you know what mph and rpm through the beams? Once you know the trap speed, then you can use calculator charts that show you what happens with different gears, tire size, wieght, rpm, mph, etc.
Looks like you can use more tire. I've had 275-50's on 15X7's without prob's. 295's may rub the shocks.
2 stage for burnouts? Only thing i've messed with is MSD digital-6A-plus and gutted hei distributor.
