I wanna do the same but I'm wanting to bore 30 over with p&p vortec heads and a cam and stay tbi. Now I don't know any shops around here that tune obd1 and I can't tune it myself. Any suggestions? And does anyone have a similar setup I'm wanting to know what hp and tq numbers this setup will crank out.

i have done this as well but in an s10 blazer..and to be honest it was pretty easy as long as you have all the parts and tools on hand it can be done in a few days if your not in a hurry. and i fabricated my own frame mounts.
