Welcome Jerry. In case no one else has mentioned .... Nice truck!

TOJ (The Other Jerry) can advise on some interesting rebuild options for your 216 to make it a more modern, more powerful engine on the inside. He has projects in the works in his shop that are really very interesting that may be applicable to you. The cool part is that its still the original "engine" (um, block and head at least) ....

Beyond that, I'll let Jerry 'splain further what possibilities exist.
Anyway, we're glad to have you. And your truck.
TOJ
