Today I will post a bit about Center Squirter Holley Carbs.
Many people are aware of the 660 cfm #4224 Holley carbs with the center squirter
design and the 1-3/8" Venturis and 1-11/16" throttle blades.
These carbs were used on hundreds of Chevrolet SB Chevy Drag Race engines.
AND a few Pontiac Engines like Richard Burnhart's GTO.

The 850 CFM #4223 center squirter carbs had exactly the same design but had the normal 850 cfm carb venturis and the slightly larger 1-3/4" throttle blades.

These were the LARGEST MECHANICAL SECONDARY (NON DOMINATOR) RACE CARBS OFFERED IN THE EARLY DAYS. i have provided some pictures below showing the features of the carb.

ps my computer had a computer glitch and would not allow me to post pics or excel file info for a few days so the Tri-Power info for 1965 and 1964 has been on hold.
