I have a brand new nos Mopar r2 block never been used or bored. Its factory bore of 4.00 and that’s all I know about it. Part number is in pics. I bought to use in my turbo demon with w7 heads and never did. I was gonna drop it off at my machine shop and have them build it but I have changed directions. Asking 3500 located in Leitchfield Ky 42754
