hey colorado people. i just took the 360,C-6 and divorced 203 out of my 76 250. the motor runs pretty good and has a edelbrock intake. the trans works but when it's cold it takes a couple minutes to engage. the t-case works great and already has a part time kit installed. this stuff would be great for a person restoring or re-building a 73-77 1/2 f-250. i'll let it go very reasonably.
