70Or4 is the 4 speed automatic and is non ECM controlled


in the late 80s GM tranies were renamed and the 700r4 were renamed to 4L60 for non ECM controlled, and 4L60E for ecm controlled

the 2004r was the smaller and shorter in length 4 speed auto overdrive tranny and was mostly in the oldsmobiles and buicks and such


700r4 were shorter in some of the later caprices and in the vettes

about 1.5" shorter

47cheverolet, it takes more than a trans. to like pull up to a light and blow someone away... but both trans (i believe) can be built up to take some good hp. I guess it depends on if you want overdrive or not...

It's a better all around tranny than the 350.
Takes a little more work and $$ to make it really tough though.

But you'll love the OD

Deciding which trans is the better choice for your application is dependent upon what you have for a setup and what you desire out of your vehicle.

Both can be built to handle the load, but with the overdrive in the R4 you can run a steeper rear end ratio and still maintain acceptable RPM's cruising down the highway.

What is your current differential ratio and how much highway driving do you plan on doing?
