Here is what you can do if you have an old rear clip sitting around.
Build an engine tuning stand so you can work comfortably.
What do you think such a thing would be worth?
A rear clip, steel fabrication, oil tank, gas tank (
TBD), fuel pump, battery perch (
TBD), tach, oil pressure (in work), fuel pressure, remote start, ignition switch, fuel pump switch, hoses, fittings, etc. Put it on wheels for ease of moving it around and maybe even eyelets at the shock mounts so you could lift it with an engine hoist.
If you feel really adventurous, put a seat above the transmission and build on a motorcycle front end. That would be interesting.
