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.
I've had m-21's before. They are excellent transmissions. The ones I've had always were with 3.73 rear gears. They scream off the line and high rev on the e-way. This one should be good on the e-way due to it's ability for high revs. We will see how it is off the line. The guy who planned and built it was not a rooky. He had built many cars in his life and this was his best...just before he passed away unexpectedly. I can't imagine him building a 'dud'. I have reciepts for all the parts used on the car and he was a 'build master'.
