Welllll- - - - - -here's the problem- - - - -a 228 engine at 3600 RPM can only flow 238 cubic feet per minute of fuel/air mixture, and that's if it's got 100% volumetric efficiency (impossible). 90% is a more realistic figure- - - -214 CFM. The smallest 4 barrel carb I know of is a Holley racing carb that can move 390 CFM. A new one costs around $850.00 or so. That's over twice as much as the engine will ever need to breathe, even at wide open throttle. That intake and exhaust system would be right at home on a beaned-up GMC 302. They're totally inappropriate for a 228 engine, no matter what camshaft or other modifications it has- - - -it simply can't flow enough air. If you can find the smallest 4 barrel that will fit the manifold and disable the secondary barrels, you'll be somewhere in the ballpark airflow-wise, and you'll still be able to impress the mouth breathers with the hotrod equipment under the hood. The engine will run lousy until the coolant is fully warmed up, because the intake has no way to be heated by the exhaust gases. Good luck!
