I just pulled the 64-66 TSMs. 3.54 gears were standard for all 65 232/287/327 equipped cars with manual transmission. Remember, even the 232 used a model 20 in the big cars. The auto came with 3.15 for the 232 and 327, 2.87 with the 287. So a 3.54 gear is used in all stick shift cars. The 3.15 might be your best bet. The 3.54 won't be to high at 60 mph, just don't plan on crusing much faster. You can see what your actual cruise speed/rpm would be by using the calculators at www.4lo.com. Just enter "1" (for 1:1) where it asks for a transfer case ratio. Tire sizing is a good way to fine tune cruise rpm. I'd try 3.15s with the auto. I don't think you will find anything between a 3.15 and 3.54. I've driven a Classic with a 327 and 3.15 gears. That's a pretty good combo! The Ambo was the "sporty" car for AMC back then, the Classic the "economy V-8". That's why the 2.87 in the Classic and 3.15 in the Ambo. Not many people who bought the bigger engine cared about gas! -- Frank Swygert Publisher, "American Motors Cars" Magazine (AMC) For all AMC enthusiasts http://farna.home.att.net/AIM.html (free download available!) _______________________________________________ AMC-List mailing list AMC-List@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list or go to http://www.amc-list.com
