Need some help picking a carb

[jaysix]

Hey guys, I am swapping a stock 1976 440 into my 67 New Yorker that the previous owner slapped a 361 into. My question is, what is a good, affordable carb that will work well on a stock 440? Also, is there a decent electronic distributor that can be had that doesnt cost an arm and a leg. I just want to get this thing on the road and drive it before winter hits. Any help would be greatly appreciated. Thanks

As many here will tell you I prefer a nice Edelbrock 1406 over just about any other. It is modeled after the Carter AFB's that came on mid 60's big blocks or a 1806 Eddy which is based on a Carter AVS (Vacuum secondaries). I like the Eddy's because they are easy to tune and are reliable. On a 76 440 a Thermoquad would have been the likely carb on it but IMO stay away from it. They are great carbs when tuned correctly but that rarely happens in my experience. A few members here are good with them I am just not one of them. As for a dizzy you could spend a lot of money on a HEI setup but I wouldn't. Go with a simple post 73 electronic dizzy with a Mopar Orange box ECU. You can pick up a reman at Summit or RockAuto etc as well as the box. I have used the Mopar conversion kit from Summit with good results. These are my suggestions but I am sure more are forthcoming from the collective!

I will sing the praises to high heaven all day long for the Eddy 1406.
File under: For every reason you give for another carb, I will give you ten more for this one.

Thank you both!

What they said. I run a 1409 (750 cfm) but the 1406 will be fine.

I have an eldelbrock 1406 carb my 440. It runs great even though it is I guess it is 600 or 650 cfm. My problem is starting when hot. I added an insulator [3/8 inch] from edelbrock and it made no difference in hot starts.

The only thing you will need I think is an adapter since you have a late model 440 that has the spreadbore manifold set up for the thermoquad. Unless the manifold has been swapped out for a square bore unit. Let us know what it has so we can offer further advice.

Agreed ... swap out the spread bore manifold for a square bore and go an eddy carb

I'm interested in trying this carb myself.

I run the Street Demon 625 cfm. Had to tune it for a 440, works well. They come tuned for a small block. You can get a reman. Street Demon on eBay from Holley at a good price then pick up a tuning kit, it come with jets, metering rods and springs. I also run a Chrysler reman electronic dist.with the springs, weights and vacuum advance from the old points dist.

Its just the factory intake manifold.

Yup that's the spreadbore manifold.

Leave the spread bore intake it is a very good piece just block the EGR valve and use adapter. Also I do not know if you are aware but the 76 engine has a cast crank so you will need to offset balance the Torque converter by welding weights on it or getting a B&M flexplate for a cast crank then you can use your 67 converter

I bought the reman off ebay, worked great OOTB on a stock 440 square bore intake,

Im using the transmission from the 76 as well. Hopefully that is able to be done. I was going to leave the 361 in it but the tranny leaked like crazy so I picked up this running and driving 76 440 with a non leaking tranny.
