I have a carb I am thinking of rebuilding but it has me baffled. Cross reference comes back to a 396 Chevelle The numbers on it read 3878261 EH 3310 124 Here is the confusing part, the carb has Ford kickdown and a Ford "ball" for cable linkage. The ball is stamped into the arm and not a bolt on What gives?
Looks like a Ford Holley . The Boss 302 I restored for a guy used a manual choke. I can't remember if the 428 Cobra Jets used a heat stove choke.
The transfer line and left side inlet looks like Ford. Could be a pile of parts with a Chevy main body and Ford base plate. Just get a 3310 kit and rebuild it and use it.
I don't think it a 3310, kinda hard to see but it looks like it has a metering block on the secondaries. Its' dressed up like a Ford, dual inlet front bowl with fuel inlet on left. Far as I know all chevys are led on the right.
It is for sure a 3310 main body that has a Ford throttle plate and fuel bowls added. The metering blocks could be from a Ford application as well, the numbers on them would aid in determining that. As has been mentioned a 3310 rebuild kit can definitely be used. The 3878261 EH p/n on the choke horn means it was originally designed for the Z-16 Chevelle from 1965 but the date code (124) says 1971, Feb., fourth week so it is a later production replacement. The 3310 shows it is a 780CFM carb, as do the down leg boosters and the secondary metering block, all factory type (GM) 3310's used the sec. block. At some point Holley introduced the 3310-1, or maybe it was the 3310-2 I don't remember for sure. With the new List number came straight leg boosters and the secondary metering plate. The straight leg boosters down grade the flow to 750CFM and the sec. plate means you either need to buy a new plate to rejet the secondaries or attempt drilling the plate through trial and error. Drill too big and go too far and now for sure you will be purchasing a new plate.
If it were a factory Ford carb it would have C90E..., D0ze...C6ME...., something along those lines stamped on the choke horn. Sounds like you have mish-mash of an off the shelf Holley The left hand inlet float bowls are worth something for a Ford restorer.
No, it never was a 4160. The original 3310 before they added the dash number was a 4150 because it had the secondary block. When it lost the sec. block and used the plate instead that put it in the 4160 family of carbs. Why the change to the plate? I imagine it was cost savings, with some gasket changes, less metal and less machining necessary for the secondary plate, on both the single inlet and dual inlet carbs less tubing for the fuel transfer or fuel line and maybe more I'm not seeing. I worked for GM for 35 years and every little bit of material or fraction of a second in production time adds up to savings when volumes are large. No different at Holley, by changing the 780CFM 4150 3310 to the 750CFM 4160 3310-1 there were cost savings.
Thanks for the history. But it was never a double pumper like others in the 4150 family? A bit of both 4150 & 4160?
It won't help with the GM Factory number, but it will clear up when Holley changed the 3310 from 4150 to 4160 (3310-2). http://documents.holley.com/techlibrary_carb_numerical_listing.pdf BTW, I'd guess factory Ford carb with a Chevrolet main body (not original). You can check the numbers stamped on top of the metering blocks to see what their original application was.
Congratulations it appears that you have a large assortment of used Holley parts flying in a close formation. A ex drag racing buddy of mine showed up on my door step one day with a huge box of Holley carbs bad parts. He said "here I'm done, have fun yourself ". That box has served me and my son well for years. It helped build several Holley "mutts" that have performed very well but earned lots of odd looks over the years. Like the 1850 on my EL Camino that I converted to metering block and center pivot floats. Everybody asks how come that "3310" runs so good on my mild 350. Clean it, kit it, and jet it and it should be fine.
Yea, I think it should be fine. I found they used this carb on the 70 429CJ's. I think it was a replacement because it does not a Ford part number. Gonna send it over to CFM Performance Carburetors for a freshening. This is the info I have now. 4V 780cfm - Auto Jets 70 · 83 Pwr Valve 85 Venturi Dia. 1 3/8 · 1 7/16 Trottle B. 1 11/16 · 1 11/16 Metering 6382 / 5671
Those metering block numbers are correct for a 429 SCJ Holley. Along with the Ford left side fuel inlet somebody restoring one of those engines would pay a good buck for those parts.
Click on 4150 Holley, scroll down to 429 SCJ and bingo, there's your block #'s. http://www.google.ca/url?sa=t&rct=j...ReXYLs8OrYESGxurA&sig2=hzYN-5Bp6YPqWDeWqffv2w
I'm not sure what is being presented here in some of these posts. Edsel58a mentioned in his original post that the List number on his Holley is 3310. In post # 24 he states that they used this carb on 429CJ's, but the Cobra Jet used the Rochester (yes GM) Quadrajet, not a Holley. Also in post 24 he gives specs for a Holley with an automatic trans application that match those for a 429SCJ, but that is a List 4628 Holley and not the 3310. The main body he has was engineered for the Z-16 Chevelle, and while he might have metering blocks from a SCJ those numbers have not been verified by him yet to my knowledge. I'm not saying the carburetor cannot be made to work well on your 460, just that the 3310 main body is not from any SCJ.
Your correct. Like I said earlier it's a bunch of parts thrown together and could work pretty good on a mild 460. The main body if it is an original Ford piece should have a D0OF, D0OZ, something along those lines stamped n the choke horn. But it doesn't so it's probably an over the shelf 3310 main body. Post #24 gives the numbers stamped on the metering blocks.
