Product Details

Holley 0-4778C Double Pumper Carburetor

The Ultra Double Pumper Carburetors feature all aluminum construction and are equipped with metering blocks and a base plate made from 6061?T6 billet aluminum. Three different anodized color options (Red, Blue, or Black) allow for a personalized look while maintaining the ultra high strength and durability you get from billet. They weigh in at approximately 5 lbs less than a comparable zinc carburetor. The new Ultra Double Pumper Carburetors have an enhanced fuel curve for optimum performance, with many more features such as aluminum construction; anodized billet aluminum metering blocks and base plate; 4 corner idle for precise idle control; mechanical secondaries for great performance; clear fuel level sight plugs for easy, no mess fuel level adjustments; Ford automatic transmission kickdown for use on popular Ford transmissions; four vacuum ports for all necessary vacuum accessories; and for the first time on a Double Pumper, factory pre?set electric choke for easy, fast cold start?ups. The clean, polished look coupled with Red, Blue, or Black metering blocks and throttle body will certainly set your ride apart whether you are at the show or track. Dont trust your performance to just anyone, Holley is the only Modular carburetor company that has been in business for over 100 years and has powered every NASCAR champion since the 60s.

easy peasy

All went well and as expected. Process and experience were great.

Best price, quick delivery.

Very easy ordering

No problem, good price. Would like to have an estimated delivery time.

excellent service

Faster shipping than I expected. Easy order process. The ignition switch was my problem and Autoplicity part was exactly what I needed at a price better than anyone else had, with shipping included. I will definitely look to them again when I need any more parts for my Monte Carlo SS.<br>Only slight negative would be it took a few days to get an email with tracking number so I would know when my part would come. But once I got it, found it was coming sooner than I originally thought, which was great.

Great price and fast shipping. Good experience!

everything was easy and fast

Very fast shipping, the product should arrive today acording to UPS, and I order it 2 days ago. The customer service is also great.<br><br>Thanks again,

Site is simple and easy to use.

Very fast shipping and bottom line prices for every part. Awesome website. Will be telling all my friends about and using again for sure!!

So I have an old car. It's and 83, seven years older than me. I'm also a student so I don't have much money and need to make as many repairs myself to save money. I go out to the local pep boys and auto zone to to try to find a repair manual that is for my old model but it's not available. I check online and there are very few copies on line. Autoplicity had the right manual at the lowest price by a good margin. <br><br>TLDR; Autoplicity has EVERYTHING and at a cheaper price

Prompt order processing and shipping, the item I received came in good condition and I am eager to get it installed on my car. Over the phone customer support was prompt and polite, I would order from them again.

The magnaflow kit that I ordered was about $100 cheaper than any other site I could find. Shipping was fast, and relatively cheap too.
