79 Cheyanne Chevy 1/2 Ton owner

Hello board,
I just became the owner of a Chocolate brown 79 Chevy Cheyanne 1/2 Ton Truck. It is stock w/350 engine and
chrome molding trim. Interior is tan and carpet is brown.
I want to rebuilt this truck into a bad boy. Starting with
the engine, I still want to keep it a 350 but would like
beef it up and chrome it out with braided hoses and chrome
parts whenever possible.

My question is this is there any recommendations to beefing
up the engine, and chroming it out w/ keeping it smog legal
in Southern California?
