I had a guy contact me today asking if I'm interested in his R3 block still in its direct connection box. I'm working on getting the part number right now. 59* unfinished 3.91 bore 9.56" deck. I have both the opportunity and cash for a change and could use some fast advise and info on this block. What is it's value? Is this an ideal block for a serious street build 750 hp? does this block have siamesed cylinders and if so is that an issue cooling on the street?Thanks guys.
