I have an aftermarket bell housing on my 68

What would be the right casting for a 396 350 going into an m21 ?




be good

The "621" is what you need. It's being reproduced,..reportedly stronger with better machining to eliminate mis-alignment,..about $175.

I put a Keisler 621 bellhousing in my car very nice piece,littlemtight around the front bearing retaineer but very pleased over all.
