Well, I'm obviously not in support of a loose chain. Neither am I opposed to gear drives. lol. But, a decent chain will survive for years - and proven consistency are in those that bracket race every weekend and the ET doesn't change. Many bracket racers I know run chains, some don't tear their engines down in 3-6 years, and they can dial and run to the hundredth, maybe even thousands of dial in time. Also, the car over the course of that time usually won't slow up - if anything, it will run a couple tenths faster after a 100 runs. Oh, the only way your method of "bouncing 20* under load" works to show chain flop is if the distributor is locked. I'm not trying to educate the educated, but as you say, somebody else might be reading through this thread and I'm just trying to get a perspective out there..... :)
