Does anyone have experience with Carolina Machine Engines in Johnston, SC? They remanufacture short blocks, long blocks, street engines, race engines to the tune of several thousand per year and their prices seem reasonable, perhaps due to volume. BBB rates them as A+ over the last 3 years (ok, ok that does matter to me) but I would like the opinions of any of you guys who have actually done business with them. Did they do good work for you? Did they give you good service after the sale? Would you use them again? All comments, pos or neg, are helpful. Thanks!
