I just picked up one .48 ex housing on ebay, so I need one more. I will talk to joel this week. Yea, I would guess rod failure from detonation, etc. But to put a pure HP marking on a rod is pointless. Its TORQUE output that is harsh, not HP. It all has to do with R/S ratio, lenght of rod, timing, etc. There is ALOT of varibles to be looked at. I tend to do things that alot of people say I cant or couldnt do. I learned ALONG time ago, that internet talk is just that, talk. I like to experience it FIRST before I belive it, to an extent that is. I mean, 90% of the guys on this board, said I couldnt bolt a head together, and make it last, and 5k miles later, and nealry 500 rwhp, holding up great.
So what does happen when at 600 hp, the rods fail? What fails? Pictures? Bolts, bending, cracking????? Lets get technical about it if where going to throw it around online.
