ONE INCH SPACER RESTRICTOR PLATE BODY 4150 HOLLEY
DEL-TRON PRODUCTS Restrictor plate body
Part No. DEL-ALL26060
The “Governor” is a four-hole aluminum spacer that accepts tapered inserts which can be changed quickly by removing the carb. Inserts restrict air/fuel entry and reduce power slightly to prevent wheel spin and range in size from 1.000" to 1.400" for custom tailoring and quicker lap times. Spacer works with most Holley 4bbl. 4150/4160 series carburetor insert sold separately.
