2 bbl or 4 bbl??

[PAPA KENT]

after reading the terrific thread by malibukasey i have a question for the owners that have done this swap and their results.

my 62 has the 283 with a 2bbl,stock intake,powerglide with 373's.i also have a aluminum 4bbl intake with a edelbrock carb that i was thinking about installing.the carb came of a friends 283 and ran well so there won't be any expenses besides gaskets. i put 3000 miles on it last year with half of it being highway and the rest in town.now my question pertaining to fuel milage is has anyone seen a big difference in economy between the two.i am leaning towards the 4bbl for extra power "not hot rodding" just some added power but on the other hand i like the original looks of a oil bath and stock carb.and the 2bbl runs well.this is one choice that if there is little to no difference in them i will keep it stock.i have good knowledge in these areas with older ford big blocks but i hav'nt played with small block chevrolets in this way for over 30 years.

thanks for any input.
