Utah truck. Box from South Dakota, step bumper with farm pin thing, pass side rocker, cab post, floor were done. Driver side has cab post done, needs rocker and floor pan done. Chassis is 85% done, new brakes, shocks, lines, rims painted, frame painted. Previous owner planned on installing A/C, and cut holes in lower dash and purchased a unit, but I don't think I will install it.

Wrong engine (1981 Chevy 350). I am looking for advice on blocks...2 bolt vs 4 bolt.....
3970010 or 3970014? 4bbl or 2 bbl? Where do I find the assembly date of the truck?
LOVE THIS SITE, Thanks!
