If you don't have the engine in the car and want to run it on an engine dyno,Best Machine would get my vote if they are in your area. If you are doing tuning with the engine installed in the car,Jake's Automotive is probably your best guy.
Depending on where you are,I might be able to help you out with tuning on an engine dyno.
Whoever you call,make sure they are comfortable tuning Edelbrock carbs. A lot of guys just don't like them.
I would think either of the guys I mentioned would be good with them. I actually like them in dual carb applications. It is harder to overcarburate with them compared to a pair of Holley double pump type carbs.
I am sure there are other guys in Michigan too,these are just the two I know I would be comfortable with.
