Four bolt mains

RustyRatRod said
I think two bolt mains are plenty sufficient. I do know that the block has to be made a certain way regarding the main webbing. Not all of them are created equal in that area. If the block you have does not have the "extra meat" in the main web area, installing 4 bolt caps is pretty much a moot point.

I would just let the Chevy guys keep thinkin it's a good thing. LOL

I think Chevys might really need them . Machinists I´ve talked to says mopar blocks take more effort to machine . mopars are harder . And L Shepard says mopar blocks are made from the good stuff in comparison to others . I am aiming for 500+Hp. So I´m Ok . Just like to hear folks input on those Milodon ones.
