mid 80's monte's had a 3.73 (but then again they had 305 motors). Agree with gimmy, 4.11 should be ok, but if it were me, I might lean to a smaller numerical ratio like 3.73, etc. But if you have the 4.11 already, go with it and see how you like it.

Also, regarding torque converter, the 2004R used computer controlled torque converter lock-up, which you probably don't have. But not to worry, you can rig it manually (which I don't recommend because then you gotta enable/disable it with a switch as you reach higher speed/decel to slower speed - i.e. you only want the torque converter to lock up at higher speeds). Or, better yet, TCI and B&M both offer non-computerized kits for the 2004R that you install and don't have to monkey with all the time like the manual set-up. Here's a link to it: http://www.bmracing.com/PRODUCTS/Tra...al-speedometer Be forewarned - that free trans is suddenly "un-free" if you buy this puppy... ($191). There are probably other, less expensive options as well.

Here's the TCI solution, a little less expensive: http://www.compperformancegroupstore...Category_Code=
Not sure if you need to add this part into the mix or not on the TCI setup: http://www.compperformancegroupstore...Category_Code=

I like the 2004R, it made driving my 85 monte ss a blast. Even if you have to buy a lockup kit, you still got the trans for a song, so a pretty good deal i'd say.
