Ok so I'm in the planning stages right now. I've got a 5.7 gen3 long block That I want to stroke to a 6.4. I would like to make 500 to 550 hp with similar torque. Planning on Fitech efi carb rated to 600 ponies. It's going in a 73 Cuda with a 360 and a a518 trans(2500 stall) and 391 gears. Probably gonna change trans to a a500(2500-3000 stall) trans with lockup. What cam, piston, comp ratio and head work to achieve this on 91 pump gas?
