The Eddy bowl problem is easy enough to solve with a thermal spacer.

Don't forget mundane things like new HEI distributor, making sure the radiator is up to the new motor, fan and fan clutch or electric fan setup, transmission cross member, new motor and transmission mounts, etc.

Amazing how much money things like that can eat.

Driveshaft length?

If you still have the external regulated alternator, be a good time to swap to an internal regulated version. Especially if you go with electric fans.

What is the planned end use for the truck? Street cruising, daily driver, mainly highway, towing?
