elgecko Dave have you tryed to talk to either the Nascar guys or 1/4 prostock or top fuel. I know that nascar motor builder tryed this when it came out. Never saw anything on how much better the parts lasted. I think that it all comes back to how hard you are going to push your motor and how well the machinist did his job. If you put a 6500 rpm chip in your MSD box, and use a PRE-OILER EVERYTIME before you start your engine. I see no problem with a motor going 50K under hard abuse. Once a year I would pull the
oil pan and check the rod bearings on clearance. There are alot of tricks to do to engines, coatings for pistons,valves,crank, heads to help heat stay in a certain place,
oil drain back to the bottom fasterand the list goes on. The car you drive to work everyday doesn't have any of this done and still will go 100K if the
oil is change on a 3K. I would tell you to save your money and buy top qualitity parts. Crank ,rods, and pistons, and bearings. Your car is not a GUN barrel, but it may travel alot farer than that bullet and still hit it's mark
