Does the bottom end need a rebuild? If so, this would be the time to up the compression, zero deck & new pistons will make for a nice upgrade. If the bottom end is still solid, just go with a good valve job, comp xe256 cam or equivalent, double roller chain, eddy performer intake & a 600-ish carb & a thin (.028" or so) head gasket. Run headers, free flowing mufflers & 2.25" exhaust. It will have great street manners & be fun around town.

There's a build for every budget & this one can be done for not much at all.
