My new to me build in process does not have a battery. Its fully packed with electronics, A/C, Power Windows, Door Poppers, Electric PS, Electric Water Pump, Electric Parking Brake, Fan, Fuel Pump etc. Car will be pretty demanding electrically. I know some have gone with the smaller Lithium batteries. Car is a Gen 1 with 347 Ford, EFI and its not clear to me where the PO had the battery mounted but it was go kart at one point. The whole wiring harness was pulled so pretty much a blank canvas for wiring.

Any advice on battery type, size, location is appreciated.
