Quote: I bought a R block last year to build a Big Inch small block, but after talking to RyanJ on what I had. At this point I will be going with a stock block build. Since I have a 9.20" 59 degree 48 babbit cam tunnel block with a 3.990 hone finish bore. What happened with that R3 block was Mopar line bored the cam tunnel in those 59* Siamese bore 9.20" R3's accidentally oversize to the 48 degree dimension.... the problem with that is no camshaft core ever existed for a 1.998" journal on all 5 cam journals AND 59 degree lobe spacing & bank angle. Basically what I'm telling you is there is no camshaft you can buy to install in your bock.
Where did you get that block? I think I saw that one .
