More specifically, some details. This first set of pics is my torque converter. I'm hoping someone will recognize it as a specific brand, stall speed, anything. I'm not planning to change it but would like to know at least a little bit about it. Pictures of the rear end to follow.

 

Here are the photos from the rear end. I'm looking for a ratio so that I can correct my speedometer. I'm told its a posi and don't have any reason not to believe that. It's clearly a Borg Warner unit, although I can't find the serial number that should be on the axle 3 or so inches out from the diff. It's disk rather than drum if that helps. The car is a 91 camaro but I don't think either part is original.

Thank you.

 

as far as the rear goes remove the cover. you will be able to see if it is posi or not and also you can count the teeth on the ring and pinion to find the ratio. you can also compare the shape of the gasket in a summit racing or jegs catalog to see what rear (10 bolt, borg warner 9 bolt) or count the bolts on the ring gear to carrier. Thats going to be the best way to I.D. the rear since changing internals is common and not overly difficult/expensive compared to other upgrades
