340 rebuild recomendations

The Demon has a fiberglass hood and front bumper. Full interior, with a racing bucket for the driver. 20 gal fuel cell, and the old one removed. The battery is in the trunk.
Has a 12pt cage, sub frame connectors. Stock springs with Cal-Tracs. 727 transmission.
I have not weighed the car but figure it's not real light with all the add on's
