Mopar R3 Block

I am asking for the tech information required to make a sensible R3 59 block purchase. Any and all talk about my potential funding is out of bounds and was, is tacky at the very least. You guys may find another thread and harass someone else. The rude comments are not enjoyed, requested or appreciated. I am building a ground pounding small block street beast. I don't care who likes it. I have NOT attacked, insulted anyone else on this site for their vehicle choices. Either be helpful and cheerful or move along!!
