Hello, I have a 71 fastback driver/project, 351C, 2V, C6, 3.0 diff. Freeze plugs are corroded and the main seal has a small leak. Removing the motor this weekend for a very mild rebuild. Edelbrock 2750, Holley 650, long pipe, Explorer 3.5 rear end, 1800 Stall. Needs paint as it was a desert dweller for the past 30 years, but no rust. I welcome any advice beyond what is already abundantly available here on the site.
