I'm not saying aftermarket parts are necessarily better and I never said ALL aftermarket parts were overdesigned. I was refering to the overall approach to the engine build. You overdesign the block to handle more than what you need. Of course it's not that simple, but staying with components designed for 332-350 hp and boosting it to 550hp or more isn't the correct path either. The reliability aspect isn't guaranteed when you do ANY type of modification. A huge factor is going to be on the mechanic doing the work.
