I do not know if I ever asked this question before but other then the carb what would be the difference between a 2 bbl vs 4 bbl 272,my 55 originally had the 4 bbl version but I stupidly sold it and trying to make one again but picked up a good running 55 2 bbl 272. Going to use the 57 intake and newer distributor and newer exhaust manifolds on this 272.

Compression ratio difference? 4barrel probably had higher compression.

As John brings up, there is a compression ratio difference. The compression ratio for the 2V engine is 7.6:1 while the 182HP Special has a CR of 8.5:1. Early production 182HP Specials had ECL-6090-B cylinder heads while later production 182HP Specials had the ECG-6090-A heads. These are casting numbers and not part numbers.
