I have a 07nnbs rcsb it has a magnacharger with stock pulley and a 230-232-12 futral cam it has a level v rpm trans with a precision industries 3-disk 2400 stall. truck has stock 3.73 gears and will very soon have 275-30-24 tires. Trucks best 60 foot time with denali factory 20 inch wheels is 2.01 and dosn't spin at all, really dosnt pull very hard until it gets going then it gone. I know it needs a bigger stall speed and maybe gears but how big of a stall should I have them restall it to. Any Input? I don't drive everyday but want to be able to if I have to. Really just drive on weekends. Thanks

 

anybody ?
