Yep, use will dictate actual life. Someone could be at 750 and granny the thing all the time with an occasional romp and it live for 50k while a guy at 525 who beats it at the track every weekend is opening the motor at 10k. People will also need to understand that with increased power comes increased maintenance efforts.
You guys are making me feel paranoid now. I've been running around feeling relatively safe (576 RWHP). In the back of my mind, I keep thinking about all the guys on here dragging and tracking their 5.0's with 620+ RWHP.
Just so I understand the consequences, what am I looking at as far as money goes? Can the entire engine be toasted? What if it's just a rod, or just a piston? I wouldn't have attempted the SC install myself, let alone building an engine, so I would have to pay someone to do it. Do performance shops like Evolution and JDM do that? How much would it cost to have all the forged whatchamacallits installed, including labor? Has anyone done this yet, or do most people wait for something catastrophic to happen first, then invest in a rebuild?
