I have a 455 that I'm dropping into an 85 LaSebra 2 door, I would like your opinion on the proper stall speed for the converter and the rear end ratio for mostly showing off at the light with a mustang or whatever, and good highway driving as well, if its possible to have both. -bob

Thank you very much for the reply. That cleared up a lot. That's exactly the direction I want to go, and will. When I do get ready for the rear end, is it possible to use the existing rear end with just a possi kit perhaps? I thought just a kit and a weld job to strengthen the outer casing. -bob

What is the Olds LaSebra (85), is this a B body? and can I use a B body rear end for this car? I don't know a whole bunch about the chassis and wondered if I could use the drive train from a 72-73 Olds Hurst. I have the 455 built up to drop in it, but need a posy rear end.
