4 speed VS Automatic
A automatic will. A manual trans car can tolorate a bigger cam and more gear and when equiped with the exact same engine, in, at a race track, you can use the stall converter to your advantage, hi stall launch and trans brake, shift quicker.
However, if you learn the 4spd well and I mean real well, you can stand toe to toe with a auto trans car. You yourself must be able to shift the trans as quickly and without any effort as quick and efficently as an auto trans to compete.
Good luck with that, start slow and work up speed.
