I am just now getting around to messing with a motor that I have had since the early 1970's. It's the low perf version, and I have managed to keep all the big parts except the exhaust manifolds, which must have been lost somewhere in the life journey. My question revolves around machine shops. I have done a ton of reading over the years, and talked with a small number of engine shop guys over the last few months, and since developed an apprehension about taking the big parts to just any shop. I have rebuilt engines in the past and want to do the assembly myself if I can get the stars to line up. My recent shop guy conversations can be reduced down to one that gave me a warm fuzzy, but this guy only does the work if he is doing the total job, machining and assembly. Can anyone suggest a reputable shop with 348/409 machining experience in the Carolina's or neighboring states???
