Holley0-80770 4150 770Cfm V-Sec/Ec S-Avenger

I took off my Elelbrock performer carb because it gave me lean spots and surges. I decided to try this Holley and it's awesome! Looks great on my '65 Falcon with a 351W stroker motor (389ci). I bolted it on with no adjustment at all and took it to a car show where I was greatly encouraged to put it on the dyno truck that was there. It pulled 330HP, 340torque at wheels with an auto overdrive tranny. Not bad! Smoked all the imports and fuel injected dime a dozen crate motors. I learned later that the carb was only open to 3/4 throttle because I didn't have help to properly adjust the gas pedal linkage when I had put it on (takes 2 people). I wonder how full throttle would dyno with this carb?

Excellent carb, adjustments were very close as described. Engine started up no problem, followed directions. Called Holley for correct TH350 kick down bracket, replaced Holley 4150 4barrel double pumper. Vacuum secondary a must with electric choke.

Works great so far right out of the box.

Thank you very much.......

I installed this on my 1968 convertible. The gas inlet fittings were bent, they leaked and my car caught fire. Total disaster. With a brand like Holley, I expected better quality. The carb seems to work fine, but I need to rewire and repaint the car.

Amazon offers a great price on this product, with free shipping how can you go wrong. Great carburetor, looks good on my classic, easy to install and set up.

put on truck , truck back fired blew out excel pump first day .

very good
