2.3 bottem ends are really tough by design. Having one main journal per rod. I have had a few with high dollar pistons, rods, and lightened cranks. But I find little difference in performance and reliability of the high dollar parts. doesn't justify the cost (for me anyway) and if your running on a short track and run less than 7500 rpm, stock parts do well. The bottem end is already tough, and your power is made in the head. If fact out of 3 cars with 2 seasons each, we haven't had an engine failure. Always use good rod bolts. I will say if your running on a longer track, or sustained righ rpm, I would consider a crower rod. Keep that oil clean. And let it warm up before blipping the throtle too much. I've seen a few of those throttle happy guys get in climb all over the throttle before they even get off the trailer, break oil pump drives. No telling how many are weakend this way and come apart on the track.
Just my thoughts.
