The Stovebolt Site Forums The Shop Area Driveline Rear gear ratio.

If it don't have a "E" in it, it ain't "E"lectronic. In other words, not computer controlled. I believe it does have 12V supplied lock and a TV. You are well advised to use a 200R4. Small size and good tranny. 1st gear is 2.7. Be aware of BOP bolt pattern. If 200r4 was used in those, it may not have a dual pattern. Just check that it fits a Chevy motor before you buy.
Stay with the rear ratio until you drive awhile with the 200r4.
