So I plan on running a Silver bullet and mach 6 injectors....So here's my question, with the mods I have what do I need to do to the transmission?

I was thinking a billet flexplat, input shaft, 3 disk converter, valve body, new lever arm. Do I really have to run the bullet piston, accumulator, and the other little things??

I'm just buying the parts and having a guy down here put it all in for me

Thanks
