Monroe or Gabriel gas charged shocks are a great value for stock suspensions. The gas pressure gives them a quick recover rate and smooths out the ride comapred to a traditional oil shock. If you are stepping up the leaf springs or t-bars, your going to need mroe shock than those two to control the motion.
I've heard lots of decent feedback on Edelbrocks and their inertia sensative valving. No personal experience with them. I beleive these are actually made by Monroe for Ebrock. However, non-compete clauses means you probably won't find a Monroe equivilent of these in the catalog.
I've heard mixed reviews on KYBs. Some find them overly harsh, some like them. It seems that most of the feedback about their harshness has come from guys with freshly rebuilt suspensions. Not sure what to read in to that. They are a high pressure shock so they generate a fair amount of resistance.
Bilsteins and Konis will transform the manners of your car and will be the last set of shocks you ever have to buy for it. Both companies offer rebuilding and revalving service. Step up the rates of your bars and you can have the shocks revalved to match.
Decent value for the money is QA1 single adjustables. Their stocker star line bolts in to the OEM locations and the adjustment knob makes tuning easy. Want a little stiffer reaction to street driving, turn em up. Making passes at the strip and want to loosen things up, turn them down.
