Upgradin' my '85 c10 custom

[jhngardner367]

I've decided to do some upgrades on my '85(the one in my avitar).I got the truck in May,2008.My uncle passed away in 2002,and the truck sat for 6 yrs.His grandson was going to get it,but decided to get a "street-burner",instead,so my aunt gave me the truck. It came stock with a 305engine,th350trans,w/lockup converter.Heavy (7-leaf)rear springs,and 3.73:1 rear gears. My ideas are: replace the 305 with a 350,swap the rear gears to the 2.73:1 gears,retain the springs,heavy-duty brakes,and add the rear air-shocks,gas-shocks front,and the heavier front coils, from my GMC.I've already put dual exhausts on it,along with a Rochester Quadrajet from a '70s Impala. Inside ,I camo'd the dash face& door trim,as well as the trim insert on the right side dash insert,I'm also recovering thebench seat in black w/camo inserts(I'll post some pics,as soon as my wife brings the camera back).There are other things,like cruise control,delay wipers,but that's for later. Any opinions?
