I recently purchased a 1957 T-Bird with a manual transmission w/overdrive.

Unfortunately, I discovered, after I purchased it, it had a 292 engine with the 2 barrel carburetor. (That's what happens when you assume) All the literature says that all automatics and cars with overdrive come with the 4 barrel 312. How this one got through is a mystery. The ID plate says it's a "C" code, which is the 292.

My question is: Can I convert this engine to a 4 barrel and get better performance? I already bought the correct carburetor and intake manifold. Haven't made the change yet and was getting different answers from people (who probably don't know). I want to keep it "stock", so don't want to make any additional changes.

Thanks
