I am in the process of doing a 1978 King Cobra Restomod project. I know nobody likes the Mustang II. Anyway I started this project almost 2 years ago. I have a 347 stroker ready to go in. I purchased a rebuilt C4 set up to handle big HP for it about 2 years ago. Since the project was on hold for a long time I have forgotten all the specs on the C4. I thought I remember it as having a standard automatic valve body. However I took it off the shelf yesterday to get it bolted up to the motor and discovered a couple of things that make me wonder. There is no kickdown lever installed and the vacuum modulator hole is plugged with a freeze plug. This all makes me believe that is has a reverse manual valve body. Is my assumption correct? There is no way a C4 can shift automatically with out a VM, correct? If my assumptions are correct, what are your guys opinions of street driving a manual VB? Any input would be greatly appreciated.
