S&P makes a sweet a/c kit. The fuel pump I used is a 93 corvette and works great. As for wiring, S&P knows their stuff along with many others. Stay away from Dynatech Motorsports in the LA California area. He advertises on Ebay that he builds a harness in less than a month but it took him over 6 months to get mine back to me even though I nagged him constantly to send it back. Get Allen to burn you a PCM. He did a good job on mine. You'll need truck manifolds most likely. I didn't try the f-body exhausts but the truck exhausts fit really good. You'll need a 4.8/5.3/6.0 truck oil pan. Don't forget to budget money to shorten the driveshaft. The crossmember can be slid forward or backwards as needed.
