The GM engineers working closely with Carter tried it out on 1953-1954 Corvettes with 3 x 1 Factory aluminum intake with 3 original Carter type YH 2066s carburetors. Wow factor, yes. Performance increase, yes a little. Street wise it was good. Put to bed by the humble 265 V8 with a 2 barrel carburetor in 1955. Talk to the classic Corvette owner's about the issues and effort they put into maintaining 3X carbs. The 235 has been carbureted to death. The next hope is possibly MPFI (see picture for 250 intake) but the "baggage" (wiring, tubes, computer etc.) get in the way of desired appearance." End quote
The "issues and effort they put into maintaining 3X carbs" were LARGELY self-inflicted!
I personally have a "love/hate" feeling toward the Carter YH carbs. Love because they are excellent carbs; hate because of some of the early Corvette owners. These were some very reliable carburetors!
There were 4 separate and distinct generations of the Carter YH, and until we started producing kits, only one aftermarket kit available at the FLAPS. And everyone "knows" the dealer parts are way overpriced, why should anyone ever buy parts from the car dealer? ANSWER - to get the right parts! The aftermarket kits had only 2 of the correct bowl cover gasket (the one for the Corvette was not one of these), the wrong fuel valve (the correct one was more expensive), and for about 6 months even had the pump diaphragm turned inside-out!!!!!!!! But yet these early Corvette owners would buy the FLAPS kits, and then gripe about the lousy Carter YF, when they could have just gone to the Chevrolet dealer and the cars would have performed as Chevrolet designed them to perform! Oops, just fell off my soapbox!
