True Bracket Car vs True Street Car....
The advice I would give to someone with say a stock 360 Duster with street tyres and 2.76 gears is to change the plugs before you run, make sure your motor/induction are running well, check timing etc. etc., as far as the launch well not much there you can advise, try different pressures, heat them and try, or around the box, stock set ups normally run better with some wheelspeed to get up on the motor, not the tyre. Also depending on the gearing you could tell that person when to shift basing it on the motor combo/power range and not use 3rd before the traps otherwise it'll kill things stone dead.....so there are other things apart from a converter/gears and all the rest.
