Re: fmx,c4 or c10
Stick with the FMX it'll handle 300-350hp easy. Although for the other items you listed a C4 has more options.
I've had issues without aftermarket shifter cables stretching. I'lve gone back to a stock shifter. As it's cheaper for my hip pocket as a stretched cable won't put the box in gear correctly. Misaligning valve body oil passages, in the long term causing box failures. If you go aftermarket make sure it's aligned riight.
