Hello, I´m collecting parts to get ready for transmission rebuild. I dont have F-body anymore but since Caprice share almost the same drive train i would like to ask you for a help with choosing correct torque converter. I have 87 Caprice with a stock 305 V8 and 2.56 rear gear, stock size wheels. What is factory stall speed and is a good idea to use some different stall speed to help to performance a bit? Thank you for your suggestions, have a good one :-)
