haha! um both!
Rick, I attribute my longevity to amsoil!:cheers:
I've watched your car thread on moparts and I love what you're doing.
Welcome!
Seriously though guys...I mean no disrespect to anyone. I'm just kidding.
But fundamentally I hear a lot of things that it turns out simply just dont hold any water.
Same goes for cast cranks. I have heard for years how horrible they are, yet Brian H is building some damned good cast crank engines and putting people in the 10s, Not for a weekend either...with reliability!
The same can be said for anything. Elmiminate all of the variables that can cause something to fail that ordinarily wouldnt and you come to find that a lot fo things arent anywhere near as bad as people make them out to be through the rumor mill.
I am still waiting to see some evidence of how bad a geardrive is, and while I am waiting for that, all I am seeing and hearing is how good they are.:read2:
On my last motor I used a mopar timing chain which was supposed to be good. Well when I pulled it apart, it was hanging off the lower sprocket like a raw egg on a nail. It was all stretched out, I'm willing to bet if for some reason I turned the motor backwards it would have skipped teeth and gave me a really bad day...before the oil pressure issue would have. LOL
Let's get some more time with these things and see how bad they are. Thi way we have solid data if something is good or bad as opposed to pseudo-scientific speculation. I understand the theory trying be conveyed, but in practice I'm just not seeing it. Maybe on a very high revving engine "harmonics" can be a problem. That's definitely plausible, but on a 500hp 408 turning under 6500, I doubt it.
