Jon, You have a couple of years on me, but not many on driving vehicles. A carburated car will not perform the same way as a new port fuel injected vehicle. Some adjustments that cover some of the shortcomings of a carbureted vehicle may not allow the vehicle to meet emissions. There is a reason that all manufacturers switched from carburetors to fuel injection. Performance, emissions, fuel economy, etc. There are just a lot of variables and this is another one to think about...not to dismiss to keep looking.
