advance cam timing to help 310 low end?

Has anybody tried advancing the relative timing of the cam to the crankshaft to play the game of getting a little more low end trading off for a little on top? I've done this with cars and it does make a difference, but I don't know if it would have much benefit on a 310. I'm wondering if anyone has tried it and seen any positive results?

Thanks

I too have done this with cars and had very good luck, but with the bikes I see a problem.
You can only go the degrees that the cam gear teeth will allow you and that would much more than you would ever do to an auto engine. That would be about 20 degrees crank movement per tooth and about the most you would ever do in an auto engine is about 6 degrees. There does not seem to be a pin/bushing on the market for bike cam gears or an easy way to get there with the current cam gear setups in most bikes, like there is for auto engines.
