I had a similar experience with the 8BA engine in my old '36. The engine was a fresh 276 Merc with a Holley 390 and an MSD "Ready to Run" ignition. When I took it to "Back to the Fifties" in the middle nineties, the State of Minnesota had a voluntary pollution test set up right in the event. Out of curiosity, I ran the car through and they told me it would have passed the then current Minnesota pollution standards as it was.
