It goes back to LOTUS's design and Merc Marine's credit for building an engine built to last in competition. Again....NOTHING about the SBC can be attached to the LT5: not parts, and certainly not wear characteristics, apparently.
It (the LT5) is a completely different animal. Forget everything you know about SBCs, wear and endurance characteristics, etc., when considering the LT5. They don't apply. The LT5 motor is a "clean slate": a complete "do-over", far as V8 design goes...which is ONE of its more intriguing aspects!!

I also agree.

My 1990 Charcoal ZR1 at 61,000 miles runs like new.
