You rang? Seriously, a motor thats well broken in works better with nitrous. I know some truck guys that file the ring gaps on the top rings, but as long as you have good oil pressure and compression, high miles today with our modern oils means nothing. Now I have 230,000 + miles, recently replaced timing chain tensioners, when I got the original ones out, they looked like new. Wasted my time replacing them. Run the hell out of her, change your oil and grin.

My friends with Fords and Chevys still tell me how weak our hemis are, but they never come to the track! BTW last year a guy in an original SS454 Chevelle blew his motor trying to catch me at the track. Perhaps our motors are stout?
