1965 barracuda formula s

Being a formula S would this not have a commando engine with 4 barrel carb and intake. Or being an old car the engine could of been changed? Thanks. Kim


For what I know all formula s barracudas from 1965-1967 had commando engines with 4 barrel carb set up due to the high compression domed pistons for higher horse power this type of model had.
This 273 commando that my car has is a matching number to the car.
