Do you guys think I made a mistake with this setup: TKO 600, 0.64 OD, 3.77 rear end, 331 stroke with Comp Cam 280 HR10 cam (HYDRAULIC ROLLER: Street machine and limited high performance street use. Best with 5 speed, 3.40 to 4.10 , aftermarket intake and headers.). This setup should produce 2500 rpm at 78 mph. I'm in West Texas with little traffic and 70 + mph speed limits on the highways so I'll be going 70 - 75 mph most of the time. It was this setup or the 0.82 with 3.54 which would produce 2500 rpm at 62 mph.
