But I have a BSME, so I'd consider forged internals for longevity/fatigue when boosted to those numbers, but that could always be done at a later date.



In fact, i'm not sure if there are many companies still around that provide a 4.0L kit. I know Brian Crower still has a kit, but it's at 4.34L which is what I plan on doing in the long run
