Note: This Carburetor ONLY COMES With (1) ONE Base Plate and (1) One SET Of Metering Blocks. 


The Other Base Plate and Metering Blocks Where Just Being Used For Set-Up Purpose's until the Correct Ones Came in. I Also Wanted Everyone To See The Blake Braswell B9 Nascar Base Plate Closer.

This Carburetor will come with (2) Two Shooter's, A .037 Shooter with Nozzles and a .040 Standard Shooter for the Secondaries as well as the Chrome Fuel Line. This one turned out very nicely and I am building/Completed Now and is Listed a 750 DP that is Just as nice if you need a Little smaller Carburetor. It's an Old School 4779 No Dash with The Roller Linkage and Looked New Inside When I took her apart. Check it Out Under Holley 750 Double Pumper.

 PS: The Throttle Shafts and Linkage are DLC Coated on the Base Plate of This Carburetor and CFM is Estimated at 870 with the Cut Choke Tower/Base Plate Combination.

On May-14-16 at 00:41:48 PDT, seller added the following information:

Forgot to Mention, DLC is Ion Bond Diamond Liquid Coating, and I have used it before on Parts. It is extremely hard and about the only way to get it off was a grinder. A file bonces off of it Too. I could stand it on a buffing wheel until my hand would blister with coarse compound and it did not even think about coming off. Works really well on 1911 barrel bushings and barrels as well as other high movement parts like Camshafts and Lifters.  It's Good Stuff.

Driven: Citroen DS4

Mon, 21 Nov 2011

Recomissioning the DS name looked like a risk to many outside Citroen’s headquarters, including us. And the new sub-brand’s opening salvo – the DS3 – didn’t exactly calm the worries of those of us who hold the original in high esteem. Where was the ingenuity?
