GM - 48 (with a circle around it) then under that 3835253, then under that 18. Where can I find out about them. Thanks - this is my first restore and it's all new to me. | | | | | Joined: May 2001 Posts: 7,438 Extreme Gabster | | Extreme Gabster Joined: May 2001 Posts: 7,438 | Go to inliners web page and click on "casting #s" and you'll find that number was used from '42-53 on 216 engines. | | | | | Joined: Feb 2005 Posts: 7 New Guy | | New Guy Joined: Feb 2005 Posts: 7 | | | |
