Could be 2.93, 3.08, 3.36, 3.42, or 3.55. Need to check the RPO codes to determine which.

3.73 if you have a 350good engine and automatic transmission

You can refer to your user manual to ID the rear end gear ration in 80 Chevy pickup.
Well, that's kind of a 'hit and miss' question if you will. There should be a metal tag attached to the outside of the rear differential cover. Remove it and take it to a Chevy dealer and they could definitely tell you what the gear ratio is.
There should be a tag under one of the bolts on the cover of the rear end. If it is not there you might be able to look on the Build tag somewhere in the Blazer. I think it is on the door or in the glove box. If you can not find it there you can take the VIN number to your local Chevrolet dealer and the parts department can look it up for you. If you are looking for a replacement rear end, a good salvage yard can do the same thing for you.
the '52 should have a 4.11:1 ratio in it currently. If you change it out for the '54 rear end you will have a 3.55:1 ratio. As far as changing it, it should bolt right up. Do you have a more specific question?
It will hold almost 3 pints.
usually on the rear lower end of engine--follow + battery cable
Check in your glove box for the code... 2.73=gu2 3.08=gu4 3.42=gu6 3.73=gt4,gq1 4.10=gt4 G80=posi trac
