Re: 272 to 312 Swap?
If the '55 272 is original...
the 2bbl carb, distributor and intake manifold may be specific to that year only.
Exhaust manifolds were upgraded / enlarged in '57.
Using the '57+ versions of those parts is a definite upgrade and will compliment the performance potential of a 312.
An oem '55 Fordomatic behind a 272 would be the air-cooled version.
Ford upgraded the FoM in '56 to a fluid cooled version for the higher HP 292's & 312's.
Is the Fairlane still 6volt, or 12v? The ignition & coil wiring is different.
'55, '56 and '57+ use different water temp sensors that don't interchange.
