Can someone educate me on 4-speeds

1. If it is in a 2WD truck, it's most likely the 833 O/D, which has the very low first gear with a 0.73:1 4th gear.

2. The 833 O/D's are not known for their strength. However, Passon Performance could probably hook you up with what is needed to beef it up.

3. I believe all trucks came with the B/E-body tailhousing. You can make this tailhousing work. You'll just have to make a bracket that moves the shifter mount in between the 2 factory mounts, if that makes sense.

4. I ran into shifter and linkage problems with my truck 833 O/D when putting it in my B-body. I just got the required B-body shifter and linkage. Problem solved.

5. Not sure on bellhousing/flywheel applications, but I'm assuming the truck has a small block. That bellhousing should work on any small block.

I hope I got all that straight and correct.
