so far I have used 2 different shops and getting ready to go to my third,,ALL of them have been and still are multi brand shop's,the first guy started doing claimer motor's under contract and had to give up his normal clientele to keep a steady workload coming in, the second guy finally gave it up and retired after 35 years of machining to finally start enjoying the fruits of his labors,both guys are dam good at what they do, the third guy also has a impeccable reputation and works on every thing from street beaters to pro stock stuff,,why in the name of satan would I not give this guy my trust to do it right,the way I look at it is, that block, crank, rod's, etc. don't care what logo is on the valve covers, if the man can do the job then the man can do the job,Period!
