I have a gen lll 6,0 LS (Lq9), that I’m going to be rebuilding and putting in my 1972 C3500 GMC. I live in California between Bakersfield and Fresno. I’m looking for a reputable dyno shop to tune the engine for me. Do you have any recommendations? I don’t mind driving 3 or 4 hours if they are good. Thank you in advance.
