Last car was a '67 notch back, hi-po 273, 4-speed car. Not a formula 'S' so it came with Commando V-8 fender emblems. Cool car. That engine came from the factory with high compression aluminum pistons, dual point distributer, 4 bbl carb, high lift cam. Just as it needed some new trim, easier to buy new old stock in 1995, I am in the same predictament with my current car, a '66 Coronet 500. Center trunk trim piece is all pitted. Cuda was army green, converted to a Dupont orange/red. Previous owner had a sun roof installed. I liked it, Great air flow. Purist, not so much! I'll join the 'B' body clan and can help with questions about 273's in general.
