I've currently got a computer controlled Qjet with California emissions and a 700r4. I would like to swap in an older, non computer controlled Qjet and distributer. My questions: What are the wires on the transmission. There's on at the rear drivers side corner, and one on the front passenger corner. If I swap to the older stuff, will it affect the transmission? Will I open a can of words in any way that I may not have thought of? The passenger side exhaust manifold has what looks like a vacuum operated valve on the end??? Should I swap exhaust manifolds as well? Any other helpful hints or suggestions would be welcome. '85 K5, 350, 700r4, np208, 10 bolts, as of 10/2001; wish list is extensive.
