    Rated 5 out of 5 by from Great Carb I purchased this carb a few weeks ago for the L79 327 I have in my '61 Corvette. It worked great right out of the box. I had to adjust the fast idle speed and lean the electric choke so that it would open fully. Runs smoothly through all rpms and idles perfectly.

    Rated 5 out of 5 by from great carburetor! Put this on a customer's 351w boat motor. Breathed life into the 89 19' ski boat. Fired right up. Plenty of vacuum conventions for 80s cars. Worst part was the aftermarket dual line fuel feed.

    Rated 1 out of 5 by from poor workmenship on holley's part I deal with jeg's a lot & have no problem with them , but the holley carb that I got had a defect from the holley plant . The secondary fuel bowl leaked , 2 of the screws were loose . after I tighten them up no leaks , this is poor quality workmanship on holly's part ( not jeg's ) I'm sure this wouldn't happen again and yes I would buy holley products again .
