Help needed for my project car

Welcome to the wonderful world of FABO. You sure picked a project to start with, putting a big block into an early A body is no easy task. Get ready to do some cutting and hammering, welding and fabrication.
Yep. 67 up would be a TON easier but with good fab skills all is possible. You might start a research on the exh. man./header situtionforths model. Manual steering I hope.
