Because a Willys 650 flows more than 650 cfm but still meets IMCA 427 spec motor criteria.
The most potent carburetor currently available for the IMCA spec motor, carbs deliver instant throttle response and more torque. Available in gasoline or alcohol versions, carburetors use gloss black powder coated Holley HP 650 main bodies with 1. 250" venturis, 750 base plate assemblies with stainless steel butterflies, TeflonŽ bushed throttle shafts, and Willy's exclusive, externally adjustable metering blocks.
Give 'em a call and talk to them about a couple of their 427 race motors using the 650, that should answer any questions you have about 750 vs. 650. Not cheap either, start at $1200 and then if you add some trick options more $$.
