So I’m doing a 5.3 swap on my 1980 cutlass supreme. It’s my first time doing a swap period. I’m not sure what motor mounts shells adapter plates to use.. I pulled out a 260 cubic in v6 outta of the cutlass I know I can’t use the mounts .. but I’m confused if I can use 5.7l motor mounts for the ls vortec swap.
