old age and engine theory

[bobhustead]

A bit ago, I was running random numbers thru my mind (old locker combos, etc.) and 1.8.4.3.6.5.7.2 passed thru what's left of my brain. Took about 5 minutes, but I finally recognized it. Question 1: Am I mentally in decline? Question 2: Why do drag racers grind their cams 1.8.7.3.6.5.4.2 ?
Prompt answers would be appreciated.

1. We're *all* mentally in decline. But if you remember the 4/7 swap for the small block Chevy, you're less in decline than most of us!

2. It's the 4/7 swap!

And Mac, I have found noone who can explain it. Haven't had access to John Medlin or David Grubnic to ask since it started bothering me.

And, Mac, you apparently remembered it.

With recent reported observations that parts of the universe may be moving faster that 186,000 m/p/s and unresolved (to my satisfaction) firing order mysteries, I am going back to geocentric solar system, retrograde motion and epicycles and will try to be happy. Anyone know a good source for LSD?

If you go Druid, be sure it is the Reform Druid type, besides Oaks they're ok with shrubs...
