KB does not have the factory mounts and WILL NOT put them on as an option, when we originally ordered a block from them they said they got rid of the molds to add them many years ago. I originally had an order with them for my block and after a year on order and them having 100% of my money we finally had to get it back and go with the World. It took about 3 months to get the World block.I am unsure what I am doing with the motor at this point in time as my racing ideas have changed, I wanted the mounts as this was to go in my tube chassis Challenger which has a front & mid-plate and the original mounts are for my limiters, with the KB I would have had to redo how the limiters attach.
