Can anyone tell me 1. what casting these are [img]https://www.ebay.com/itm/291722416620?ViewItem=&item=291722416620[/img] -

ie Procomp, ProMaxx, 440 source, etc. I know anyone can put there name on a casting, I am just trying to figure out what would be comparable.

2. If they are worth buying for a daily driver or are they scrap metal?
