need rv carb recomendation

I recently bought a '77 F150 with a 400 motor and a Edelbrock Performer 400 manifold. The truck came without a carb (I got to test drive it with one) so I went to the salvage yard and they had a Holley DP mechanical 2ndary 650. Great, so I bought a rebuild kit for it and I'm wondering if I should have gone with a vacuum 2ndary because it will be mostly for going up into the mountains with a camper. I bought this carb because I wanted to find something cheap and fast. I should have spent some more and got a Edelbrock 1406 off of ebay for ~$150 instead of this gas hog for $75 (not including rebuild kit). Could've been driving it by now. Can anyone recommend anything better than an Edelbrock 1406?

Well if this is a stock motor the edelbrock would work good wise for simplicity but if it was me I would look to get a holley 600 1850 vacuum secondary carb off of ebay. I see them on there all the time and rebuild kits are about 20 buck at the auto store.

Those carbs are good for stock to mild performance. There are plenty of them for about the same price for a used edelbrock. I once had an edelbrock 600 carb but sold it after I used a holley 600 carb for a temporary carb till I got my new one and I liked it so much I went ahead and got one. Look around on ebay I bet you can find a good deal. I like the holley style carbs better cause you have more fine tuning options and better availability of parts.

I just checked ebay and there are some of the holley 1850 model carbs I mentioned in the post and they are around 100 dollars or less minus shipping. Several looked to be in pretty good shape wise so just do a search for holley 1850 carburetor and many will come up. Hope that might help for a suggestion.

I'm watching 2 of 'em right now. One for 49 bucks and the other rebuilt for 200. I'm wondering if the bolt pattern is the same as the one I have now. I have a 4150 on a Edelbrock Performer 400 manifold.

They are the same- both "squarebore" bolt pattern.

I would be very wary of an Ebay Holley, especially one that claimed to be rebuilt. There are few things as frustrating as a Holley that some jack leg has messed with. Buy new if you can, the one and only way I would buy a used Holley is if I knew the history behind it. At any rate, don't think you are going to buy it and just slap it on and everything is going to be fine.

Good advice, Vince. I'm well aware of that, being the prince of jacklegs.

If the intake will accept a spreadbore pattern carb the answer is simple. Bolt on a Quadrajet. The small primary`s make for excellant low end power and throttle response plus mileage. If it accepts only a squarebore why not use a factory motorcraft 4 barrel?

Legitimate question that I'd like an opinion or two on:

How would a marine Holley # EOJL-9510-CA List 9392 work on a car or truck?

The carb has the marine type "J" shaped vent tubes, electric choke, 600 CFM, vacuum secondary and was used on a 351W in a Ford truck.

Is there a problem I'm unaware of, w/using a "marine" carb on an automobile?

You can use a marine carb no problem.

Since you have the Holley (I assume the throttle shafts aren't worn out) why not rebuild it? Nothing wrong with a mechanical secondary, at least you know when your into the secondary's right (about half throttle).

Since you need a spreadbore any of the carbs mentioned will fit the bill but they will all require tuning, I happen to like Holley's and Autolites to tune but only because I have a lot of experience rebuilding and tuning them (best part with Autolites is jets from any two barrel fit!).

The problem is if you have no experience tuning or rebuilding any carb you will have a learning curve to go through.

BTW I would never buy any carb on E-Bay sight unseen...ever, too much junk out there.

Both the 2171 and 3771 (w/EGR) Edelbrock Performer 400 manifolds have a squarebore bolt pattern. The 2171 is shown below.

That looks like it. I couldn't find any #'s on it other than Performer 400
