Calling DIYers: Anyone use one of the rebuild kits (link below)? My aluminum short pump part number is 3975928 (GM OTC for BBC applications). Multiple vendors provide kits but, can not confirm whether the kit can also work with an aluminum pump, only that they are for 396/427 application. Most of the pumps for this application are, of course, cast iron.
Thanks, Sam
