A friend of mine used to run a 1965 Plymouth Valiant with the 273. I remember him telling me the 1965 273 had a bigger carb. From the specs from NHRA, it looks like the Stromberg has a slightly larger venturi than the Carter BBD.

180 273 DP 8.8 1-2 B&B BBD-3843S/SM 3844S/AUTO 2463252 1.5 M 57.3 B,5
Carter Carb sizes – 1437/1063
Strom Carb sizes – 1437/1125

It also looks like the 318s got a bigger carb. I never knew they were different.
