Graham Performance Engines does all my and all my friends engines.
He is a mopar guy himself but will work on anything that comes in the door. He is in Bowling Green Ohio which is 20 miles south of Toledo.
If you are interested pm me and I will give you his info.
He was just mentioned on hot rod tv for doing the machine work on a 500 caddy motor.
He is doing a 500 mopar now as we speak. My 500 made 771hp with a solid cam and nothing fancy.
