However the 4180 was made into an emissions carb and hurts performance and fuel economy. I replaced mine on my 1984 F250 Super-cab, Super-duty, 460 with C6 and 4.10 rearend and saw a major improvement in performance and MPG. Throttle response was greatly improved and mpg was up 2 mpg and when you were getting 6.5 to 7.5 mpg, 2 mpg is a giant jump. Oh, I replaced mine with a plain Jane old style Holley 4160 carb, list number 1850, 600 CFM with vacuum secondaries.
sorry to ask this after this has been here so long but what year was that carb that you put onto your 460 the 4150/4160 and was it a 4bbl or 2bbl? and if it is a 4bbl would the intake fit on my 84? i have a f-250 with a 2bbl and looking to get a liitle more out of it with out doing a whole hell of a lot to it, thanks.
