Maximum rpm for SB

I negotiated a manual box while out junk shopping yesterday. I have hoarded a few dippy aluminum master cylinders as well. I should get those on there

The only real option that my car has is PS. It is a manual disk, column shift car.

I have not decided what my weight loss strategy is at this point. In typical fashion it will likely include making lighter bumper brackets that type of thing. I really would rather not drill holes in every bracket, but I am willing to do what is reasonably easy to return to stock later.

Thanks, ROB
