Build me a 800hp NA 512 b block using pump gas

What does the car weigh?

Unfortunately that's one thing I can't answer right now. The car weighed 3210 with the complete stock interior, stock front end, stock leaf spring rear, etc. That was just before going to the chassis shop and being back halfed and a roll cage, aluminum tin work, wilwoods front and rear, 1 Kirkey seat etc. etc. Still need to replace the front crossmember with a tubular one etc. etc. Still lightening the car as I go. Lots more to rip out and the fiberglass fenders and hood are at the body shop right now.
