Increasing the oil pressure, and using good oil will help, may even make it last a long time, and I know there will be people jumping all over me saying it is not needed, but I have seen enough failures to know that there is no exact formula for making it live there. Basically a person is gambling. I've seen 900 hp trucks run a long time no cam bushings, and then I have seen them completely eat the block. My thought is this, if you have the engine at the machine shop, already taken apart, spending the $400-$500 dollars to make it way more dependable is worth the effort. Plus if you upgrade even more, it is already done.
