Hi guys I'm a new member and the proud new owner of a 73 Datsun Coupe
It hasn't got an engine or trans and wanted to get some advice about good options engine wise?
Im wanting to restore the car and keep it as original as possible, but want it to haul ass as well.
Any advice would be greatly appreciated
