So, I agree the simplest and most effective solution it to put the stock intake and carb back on the engine.

However, just for sake of discussion....GM had a factory 4 barrel for the 265 v8, correct? I know different number of cylinders, four barrels not one, and totally different RPM capabilities. But the displacement would be similar-ish. Particularly if the 250 was rebuilt over-bore.

If one was hellbent on a 4 barrel for a 250....would the 265 carb be about the closest shade of lipstick for the 6 cyl pig?
