You looking at a 9,000 rpm redline? I would be very concerned about oil problems....

Who is building your shortblock? Using extra bearing clearances? Check out this thread if youre thinking about high rpms...

wasnt really planning on reving to that level. Nor was I planning on building the shortblock at this time, most likely I plan on freshening it up but not "builiding" it.
