Big block A body spool mount K member?

You can't just plop a big block on an unmodified small block spool mount k frame without cutting and moving the mounts, OR you use Schumacher mounts, which, instead of cutting the K frame, they 'cut and move the motor mounts' themselves instead of cutting the k frame.

It can and has been done I have modified set of factory spool mounts that allow a big block to be dropped on an unmodified completely stock 73 up small block spool mount k frame.(Has been installed on 2 different K frames) Motor is tucked as close to firewall as possible and still use factory tranny mount too.
Motor sits level and is not crooked either
