Call Todd Quinn at Platinum Engine Designs. Had our 463 Big Block chevy tuned there. He used to run Larry Morgans (NHRA pro stock) engine program. I know most guys in columbus wanted $350 for 3 runs and even more for tuning. He, i wanna say is $375-400 and you get unlimited runs and time, on the dyno and he'll do tuning and anything else you want him to do to the motor while it's on the dyno. All you have to do it bring your own gas. Hell of a guy too.
