overdrive
found a Gear Vendors overdrive at the junkyard. Has anyone put a OD unit on a 350 SDL? The 603.97 engine is fragile and I don't know if if has the guts to do this with out running out of power or blowing a gasket.

Don't know what adding OD would have to do with either... Should save quite a bit of wear on the bores and bearings.
