Re: Confused ‘71 owner
Welcome to the site. If you are going to do the conversion I would suggest you investigate the manual overdrive transmission choices. There are plenty of Muncie transmissions on the market. However they are 50 + years old and many have case issues as well as need rebuilds. One could have significant $$ in making a 50 year old trans sound. Plus unless your rear end is low numerically the 1:1 4th gear ratio is not really highway friendly. With an overdrive one can have off the line grunt and good highway rpm. Plenty of info on this site about trans choices and conversion info.
