You are correct, all engines will eventually "pass away" to some extend. Your post here also puts the "Myth" in the burial ground! I know for a fact those engines are ran so damn hard and at High RPM's for a long long time.

Thank you for your first hand knowledge on this subject!

Can I ask what you guys were Revving these engines to? I am sure everyone will want to know.

those engines were 15to1 for alcohol and at Winchester VA.on an 1/8Th mile track they were trunt to 8500.for 25 laps at a time not to Manichean the worm ups and qualifying..and at hagerstown speedway in md.a 1/2 mil was turnt to 7500 to 7800 for the same amount of laps as va.one thing we did do was change oil every week and used strait 50wt.kendall oil.and every 500 laps would change rod bearings..never had a baring problem.........Artie
