I have a stock 390 in my '76 F250 and I know the carb will need some attention before I start driving it regularly. It runs ok now, but the vehicle sat for a while before I purchased it and my guess is that the carb might need to be rebuilt.

I'm new to carbeurated engines and have come across an Edelbrock 1405/1406 carb pretty cheap that needs to be rebuilt. Would like to take a shot at the rebuild and would feel a lot more comfortable working on a carb that is a backup/separate from the one needed to keep the vehicle running now.

Will this carb fit my stock 390 manifold, or will I need to upgrade. Thoughts on this carb? Will it be a nice upgrade for my 390? How hard is a carb rebuild? I'm mechanically inclined and pretty well organized, seems like something that might be doable to me.

Thanks!

 

The E-bok and the old Autolite 2bbls are basically the same design. The 600 cfm is a good pick, though it won't bolt onto your stock engine(it should be just a 2bbl carb). An intake change would be in order to bolt a 4bbl on it.

This type of carb is really easy to rebuild, only a few parts and one major gasket for the lid. Get yourself a gallon can of carb solvent(get at local parts store usually), strip the carb down, soak it for a night and then wash it up and put it back together. Get a couple cans of brake clean to wash parts off(if you don't have a sink to use), as brake clean dries clean. Don't use carb cleaner as it will leave residue.

Depending on what you plan on doing with the truck, I'd leave the stock carb on it. If you plan on hopp'n it up later, then maybe look into the 4bbl.

 

Here's a pic of my 1405 on my 67 FE block, I had to put an adjustable throttle linkage, you can just shorten yours though. Also I have a stock intake manifold so I had to grind a little off off the carbs throttle arm for clearance. I love the Edelbrock 1405/1406 series, been using them for years, I own three....two backups. Check out the pic. <a href="http://s300.photobucket.com/albums/nn21/danfordman/?action=view&current=ENGINE3.jpg" target="_blank"><img src="http://i300.photobucket.com/albums/nn21/danfordman/ENGINE3.jpg" border="0" alt="Engine"></a>

I went ahead and bought them. Yes, I said them.

Turns out, the seller had both a 1405 and 1406. He was going to sell them separately, but decided to sell them together to get them out of the house as he was preparing to move.

Going to rebuild the 1405 first and eventually swap it onto the truck. My 390 currently has a 4 bbl carb on it, so I'm guessing this should be just fine.

Once I get the 1405 straight, I can rebuild the 1406 and the original carb. Never hurts to have extra parts/extra practice.

Thanks for the tips.

 

Ok, so you have a 4bbl already, what is it? A stock Ford Autolite? I'd replace it too LOL!!
