I have a 68 American that I converted from T-96 to T-14 with overdrive. I did the conversion back in 1980 and kept the 3.08 gears. I had to use the linkage for the T-96 and readjust the shifter. I had to modify the transmission support and the mount was about an inch further back. I was not to impressed with the mpg as when there is a 30% reduction, the rear end equates out to a 2.16. With 1-bbl, points and bias belted tires the mileage was not what I expected. Today, it is a different story. The 199 now as a 2-bbl carb, motorcraft electronic igination, radi tires and the rear end is now a 3.31. With a 30% reduction, the rear end equates out to a 2.32. What difference this made. I drove this 68 White American to the NAMDRA meet this past Sept and average 23 MGP driving around 65 mph. We just purchased a new 2006 Caravan and it gets 23mpg on the highway. I think that 23 mpg on a 68 199 with 172000 miles with not rebuilt is pretty damn good. ============================================================= Posted by wixList Archiver -- http://www.amxfiles.com/wixlist _______________________________________________ AMC-List mailing list AMC-List@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list or go to http://www.amc-list.com
