I've been looking for improvements for my 2 ton LCF, if I remove the governed 2G, stick a Thermoquad on there, maybe let some air out of the 14 ply 10R-22.5's, do you think it'll get down the drag strip at 13 seconds???? The SM420 is a little slow in the gear rowing department but I do have drag gears in the rear end, it's like a quick change only you don't have to get the tools out. Or maybe I should just leave well enough alone and try not to scatter the little 283, 62-65 mph at 4000 rpm is good enough.
