I've stated in this thread that I typically got 200 passes on a set of gears in my former chevelle which btw, I'm told is about 100 more than a similar weight B/SA Stocker with a 12 bolt.

The 4.88 gears in our 69 Camaro, running in A/SA and CC/SA, as a 427/425/435 (3650# minimum at A/SA) typically last about 4 years, which is about 400-600 passes. I took a set out that looked perfect after 4 years, put in a 5.00 gear, and it went about 150 passes before the heat treat apparently failed, since the gear pretty much fell apart, mostly on the coast side.
So if you're getting 200 passes out of yours, I'll stick with what I'm doing and getting about twice the gear life out of everything but that one set of 5.00 gears.
Hey, Kenny, sorry about the bandwidth, but I found that the genius bragging about knowing more than me while getting half the life out of a set of gears that I do was just too funny.
For the original post, yes, there can be power in synthetics, or at least ET and MPH. However, in the case of motor oil, it requires a ton of testing. You need to know what viscosity your engine requires due to the clearances and the oil pump, and you need to know what base oil and additive package makes your ring package happy.
You could find a synthetic of a light viscosity that makes the engine real happy with regard to friction, oil flow, and pressure, but makes the ring package and cylinder wall finish very unhappy, and you may actually slow down. You need to talk to your builder and find out what the actual minimum viscosity for your engine is, and he should also know what makes the rings work.
Some people have found that certain automatic transmissions and torque converters really like a synthetic hydraulic oil made for agricultural tractors. But your converter and transmission might hate it.
I do not know anyone who has tried the API GL-6 and half quart or so extra that Jimmy Bridges suggests who slowed down, or lost a gear. I wish I had gotten around to trying it with the 5.00 gear, it might have saved a gear that appears to have been weak.
