Ok, i have a 12v that was dropped in 2nd gear at 70mph. #1 slapped the head and tore it up. Bore looks fine, but will be checked. I also have an awesome running 24v, with a cracked 53 block. Could i use the 12v block and ppump stuff, with the 24v head, pistons and rods. I would have the necessary machine work done and put all new bearings, just wondering if its even possible. Are the cams different? Do i have to use the 12v injectors? I basically just want a stock 12v with the pump turned up a little, not a race monster motor.
