JEGS Rebuilt Q-Jet carbs are Made in the USA.

    Note: Camshafts up to 228° of duration at 0.050" lift and dual plane or single plane manifolds are also compatible. These remanufactured Quadrajet carbs are not designed to be used in dual carb applications and should not be used with nitrous over a 175hp increase.

    Rated 5 out of 5 by from Runs Better Than New I inherited my Dad's 1977 Chevy Scottsdale truck four years ago after he passed. A year-and-a-half ago the original engine threw a rod and I replaced it with a new GM crate motor from JEGS, but my mechanic decided to keep the original 1977 carburetor. Even though the old 4-bbl Quadrajet had been rebuilt several times over over its life span, my mechanic thought he could squeeze some more life out of it. The last time in the shop the 37 year old carb was acting up and I decided to replace it with the JEGS remanufactured Quadrajet carb. Super simple installation, it dropped right into place. Man, what a difference! The difference is like night and day. The truck starts and runs so smoothly. My mechanic said in all his years this is the highest caliber remanufactured carb he has seen and said--in his opinion--it is as good as dropping in a new carburetor. He and his staff were utterly impressed at the difference in reliability over the old Quadrajet. My 77 Chevy is not a hot rod, it's a daily driver work truck. Between the crate motor and the remanufactured Quadrajet carb JEGS has breathed new life into my pick up.
