Unless your vehicle has sound deadner like a Lexus, you’re going to hear that 4.56. Cargo vans (hollow, no sound deadner) have harmonic rings on the driveshafts to absorb some of the gear whine.
Monitoring NASCAR practice sessions with headsets and listening to the crew chiefs keeping tabs on oil pressure and stating the “thin oil” will create lower pressure readings than race day oil pressures. Not sure that’s the “proof” you need but I’ve heard the discussions more than once…
I see. You are an “authority” on all things oil and performance engine technology. Even more so than Keith Dorton. You could be making a cool million a year with a career change!
I don’t know but…all the charter fishing guides that I’ve ever been fishing with swear by it. When they put 1,000 hours a season on their motors they use what works. Not a good answer but that’s what I know. Give me time and I’ll make stuff up….
And $6k to pull the engine, disassemble, probably machine work, gaskets, and etc. by a shop to install those low quality rings you are referring to. You don’t know the carbon issues in outboard boat motors (2 & 4 stroke)?
Love Pontiacs. Finally got a 68 Firebird after looking for years. Still needs some TLC though. Need some leads on quality Quadrajet remanufactured carburetors. Any suggestions?
