[quote=flu]I just might blow up a stock motor just because I have no idea what the condition was beforehand.[/quote]I would do a quick check of the bottom end of the engine.. pull a center main off and use plastigauge to see if you are in tolerance. Same with one of the con rods– don’t forget to retorque after putting the caps back on (after removing the plastigauge). Also take a light an shine it up the cylinder that has the piston closest to TDC.. check for scraping.. should still see hone marks.. could take the time to rotate the crank and check each cyl. Also do a compression test.
If all is good, should last provided you don’t over-rev and keep good oil in it. I would suggest running with oil level near the full mark on the dipstick (there are two marks.. one full and one ‘add’). Keeping it near full helps reduce likelihood of uncovering the oil pickup and pumping air on a hard corner.. until you get a proper windage tray. You may burn slightly more oil near the full level, but you will be more likely keep the engine together.
