Cool project, 'was a hemi car'
I'd leave the fiberglass fenders on it, do something about that hood
I'd leave it looking like a drag racer, but street drive it, put a 440/727tf in it
clean up & do something with the interior, & dash cluster/gauges
clean up the vintage slots (?) or is it old Torque Thrusts (?) can't tell very well,
maybe repaint paint the inners if it's a vintage TT wheel, slot front runners/polished
clean it/the body, fix some dents up maybe prime it, at a min.
&/or paint it all one color, so it's more presentable
get all the safety stuff plumbing, belts & hoses changed, fresh fuel system
& drive it, like you stole it, because you literally did get it free
a lil' cleaning & straightening out some "stuff/butchery" will make a huge difference
in the eye appeal
'day 2' baby
good luck, have fun
