Carl's big bore
I was not aware that Jacks big bores had crank issues. The Polaris ves 800 big block had crank issues and since Jack had a 910 big bore kit that fit on that bottom end, there may have been some crank failure's, but that in no way was jacks fault. In fact several people claimed that the 910 engine had better harmonics than the 800, causing the crank to last longer.
At any rate, carl's 840 and 860 big block kits are not known to have crank issues that I am aware of.
