I don't know if this is the right place to post this. I am looking for a Mechanic that has a Dyno in the lower New York area. Long Island, even northern New Jersey would be o.k. I want to get my 350 Mag looked at as I don't have faith in it anymore. It's 11 yrs old (tired) with chronic dependability issues. Before I spend the money on a repower, I want to get it looked at. Thanks

dyno time is pricey. 350's are not so pricey. usually about 500 bucks a session. do a compression test.

Go to Performance Marine in Bolton Landing NY.

Is JC Performance still in business?
