I am getting ready to rebuild the engine for my daily driver, and here is what the rest of the truck will look like; 700R4, 208, 12b and d44 with 4.56 gears, 35" BFG mAll Terrains. The engine I am rebuilding is a 1992 350 out of a GMC pickup. I have gotten rid of the TBI in favor of a Camaro TPI setup. I will drive this rig roughly 40-50 miles per day, some in town, mostly highway. It will be a mild weekend wheeler (have some 33" SX's for the weekend /forums/images/graemlins/wink.gif ) consisting of mud and minimal crawling. Now the question; will I realize enough performance and economy from a roller valvetrain to justify the expense? Longevity and reliability is a key, yet efficency and some power are desireable. Roller valvetrains are not cheap, I am aware, thus the predicament of wether to go roller for a rig this mild or not?
