Ok, so as you probably know from my build thread, I just toasted another engine. I have yet to pop the pan and see what's up, but I still had oil pressure after it popped so I am assuming that like last time, the big end is intact and I either folded a rod, broke a piston, etc.
I know the general opinion is that a stock untouched l32 is the way to go. My concern is that I can, and fully intend to, lug this engine at very high boost and relatively low rpm compared to any previous high HP 3800 build. So while the L32 may stand up just fine to 800+up on the big end, I am thinking the compression stresses on the rods will be significantly higher if I am making the same top end power, but get a ridiculous torque curve from 2,000rpms. I would ultimately like to be able to run full compound up to like 3000rpms, probably making 50-60psi boost down low.
With that said, does anybody think I should build an engine around the 4340 rods, or just freshen up a stock replacement L32? I obviously demolished the L26 at relatively low power compared to what I am planning...is an L32 really going to hold up to twice the torture or more? I'm running out of buildable blocks so I can't just keep throwing stuff together and crossing my fingers. And if I do go with the built option, forged pistons as well? Opinions?
I guess I will be better able to make an informed decision when I find out what failed for sure...but wanted to find out what you guys think in general. Thanks!
