It sounds too simple to me that a swap-over of those few parts will make the 228 carb satisfactory on the 270 (but, your logic/action might be correct).
My friend with a 270 engine in a 53 GMC 1/2 ton long-bed used a GMC Holley AA-1 carburetor with adjustable jets. It ran fine (he now has a 302).
You might want to adjust the carburetor and timing on a warm, running engine, at idle speed using a vacuum gauge (adjust to maximum vacuum reading at the wiper port on the intake manifold). | | |
