What would happen if.....
After my 305 to 350 tpi swap it has become impossible to find a chip that is a 350 with manual Trans. (I know that's because they never made them like that from the factory) but my question is, what would happen if I just put a 350 w/ auto trans chip in my car? Would I get any ses codes? Drivability issues? Performance problems? Any insight from experienced turners would be appreciated as this aspect of my car is very foreign to me.

Re: What would happen if.....
If this is your '88, and you also changed to 22#/hr injectors, it will work. Start up may not be the best as there are weight differences between a torque convertor and a flywheel/clutch. Be sure not to use a '89 chip as it has VATs.
If you still have the 19#/hr injectors, then use the 305 chip.
