will a rug c 2 toploader fit a mustang. it decodes as a 67-69 close ratio 390 transmission from a montego, ranchero or fairlane. what is the advantage of running a wide ratio compared to a close ratio.
IIRC, the wide ratio had a 2.78 1st gear while the close ratio had 2.32. The 2.78 box is better off the line, combined with your rear gears. The close ratio will minimize the drop in RPM during shifts, the wide allows the engine RMS to drop more between gears. Again IIRC, close ratio was better for racing, wide perfectly acceptable for the street.
I have been running a smallblock toploader behind my fe and i did not realize a length problem. i have the cobra jet bellhousing also. i have never had a problem, but maybe I have been lucky. The present tranny I am going to run is a rug bj1. How do you tell there is a problem. Thanks for all the info guys.
