The 288 engine was never factory-equipped with a 4-bbl carburetor. But to my way of thinking the increase from 135 to 150 hp could be accounted for by the increase in compression ratio from 7.0 to 7.7 - that's a pretty hefty increase and there were no other significant changes to the 288 that I recall. Also note the 135 hp was developed at 3600 rpm in 1951, the 150 hp in 1954 was developed at 4000 rpm.
