c20 rear suspension opinions wanted

[fattony67]

I am currently in the process of rebuilding a 1971 long bed fleet side pickup. The truck originally had a camper in the bed, along with monster rear leaf springs. It had 18'' steel wheels with a 31'' outside diameter and still had 10-12'' of clearance in the bed side. During the rebuild I plan to do some modernization. The drive train will be a rebuilt lt1 engine that will be bored and stroked with an edelbrock top end kit. I plan to keep the DANA 60 rear end in order to handle the power from the new engine. I have no interest in lowering the truck other than for improved handling characteristics. I have access to a plasma torch and welder, so some fabrication is not out of the question. My question is this, is there a better alternative (performance and handling wise) to the rear suspension other than the standard rear leaf?
