Whats needs to be done to my stock crank if i want to bore it to 4.020 and get forged 6" rods and forged nitrous pistons, wanting to spray no more then 200shot. I was wanting high comp. ratio, but with that much spray what would my limit be around and whaht would i need to do to my crank to insure the most out of it. I was thinking of tring the cyrogenics, of freezing parts for strength. Any knowledge for me please.
