i have a customer with a mr-1 block and i can back up drunk-n injun on the hardness and the cyl wall claims. after we had another issue with some machining that was done at kre and the vendor refused to acklowledge the problem we started checking for other potential defects. we also found that the hardness was way below industry standard @145-150 brinnel. the cyl. wall thickness was also below the advertised spec per the kre website. although not as bad as that block, his was below .200 in several places at a 4.350 bore. my customer has been trying to secure a refund from the vendor but has been told that it is not possible and the vendor will no longer take his phone calls. at this point he is trying to contact kre so he can get some kind of satisfaction.
