Im sure you guys are getting bored of my rear suspension questions by now but my dilema continues. As Im waiting for the next sale from UMI and I continue reading the advise given here I see that TRZ offers a setup thats comparable to the UMI. Any thoughts on one over the other? This setup is for an 85 Monte, small block, 30 over, supercharged, nitrous, 9:1 comp, P & P 882 heads, comp cams nitrous/supercharger cam, th350 fully built, 3500 stall, 9" converter, eaton posi 4:11 's.
