We have two Rodeck 350+ blocks for sale. 400 mains, no welds, no cracks. One has been punched .010 and the other .035. They may need to be bored. No other known defects out of the ordinary. The reason they are for sale is we have gone cast iron. The only possible trade we would consider is a PBM World block or a very good oil pan for a UMP modified. We also have other late model parts for sale, including oil pans, shocks, springs, oil tanks, wheels, etc. PM's only, just don't want my phone number out a public forum. My name is Ralph, and thanks for looking.
