Uncle Sam, you run that candy shop over by Home Depot? I was drooling over your brown 69 you had out for sale in front of the store. There's a few of us first gen birders around in Schenectady.
In my opinion, Jim, the M-21 sucks unless you have a high number rear end, then you rev too fast at highway speeds. My M-20 with 3:23 gears (with little tires) is OK off the line and still revs high at highway speeds.
