Take a look the stuff James Duff has.

So does yours have a 3 on the tree or is it an automatic?

Automatic

[Skyvalhunter]

Having an automatic is better. Before I got mine the guy I purchased it from bought one of the Duffy conversion kits and moved it to the floor. As most of those that had it on the tree were notorious for having problems like slop, etc. So when I got it I purchased a 4 speed out of a early 70's pickup and bought an adapter out of CA and installed that. Now when I am in 1st it crawls and in 4 wheel low/1st it really crawls.

Getting fuel to the carb now. Tank was spotless and the pickup tube in it is in great condition. Didn't know they put plastic gas tanks in these. Sure glad they did. Carb is gonna need a rebuild or replaced. It's got a ford 4 barrel on it. Still won't actually run but it fires. Uncle said something about the ignition switch getting hot a couple times. I'm thinking there's a messed up wire or something. I remember on my 79 bronco I had it woul do the same thing. Fire but not run. Ended up being something with the ignition but not sure what. Ended up selling it before I tried to fix it.

If it sat with gas in the carburetor for very long, it might have gummed up the carb.  I bought a snowblower that sat for 8 to 10 years with gas in the carburetor and it was so gummed up I just replaced the whole carburetor.  I never fooled with 4-barrels.  2-barrels were complicated enough for me! 

[Maverick]

Yeah I decided I'm
Just going to buy an Edelbrocks for it. Anyone know which one to go with for a 302? I was thinking the 500 or 600 cfm. Not sure which would be better for it though.

[Heredoggydoggy]

With the price of gas these days, I'd go with the one that gives the best gas mileage.  What little I know of 4-barrel carburetors is that they normally run on 2 barrels unless you stomp on it to open the auxiliary other 2 barrels.  Avoid cracking the other 2 barrels unless it's an occasional "get the cobwebs out."  That's when they really start to drink the gas!  Calling Edelbrock, or getting on their website will probably tell you what model is best for all-around driving...  The old claim was that a 4-barrel carb was more economical to run than a 2-barrel.  As long as it only ran on 2 barrels.

Yeah so we'll drop at least one tank tonight and see what's going on. Battery is unhooked unless we're trying to start it. I'll worry about the brake light after this thing is running. Once I get running good I'll start fixing up the interior and exterior, exhaust, lift kit and new tires. Already have new wheels for it. Can anyone recommend a lift kit? Can't make up my mind on if I want to run 33s or 35s. Not going to be a wheeling rig. Mostly one I'll cruise around in and maybe take up to the mountains for hunting.

I would never lift one. You'll ruin your gas mileage with them bigger tires and they are already really hard on u-joints and slip joints because the angle is so steep on the driveline. A lift will make it worse. I never felt I needed it.
Broncos are top heavy to start with anyway.

Your choice though.

   I have to agree with not lifting the vehicle and putting the big tires on it--unless you just want to look cool.  Ford paid their engineers a lot of money to design a driveable vehicle that will still take you anywhere you want to go.  My '90 Bronco II is bone stock, and I call it "a little mountain goat".  And I didn't have to buy a ladder to get in and out of it!

If you intend to drive on the freeway and in traffic, you might think twice about a lift.  Early Bronco's are plenty tall for their short wheelbase and already pretty squirrely.  My brother had a real nice '72 I drove for a while before selling.

Here is a picture of my brothers 69 Bronco

[Maverick]

I've always enjoyed driving lifted vehicles. Never had any issues with my 2000 silverado on 38s, my 86 k5 blazer on 37s or my 79 bronco on 35s. I've seen a lot of these things driving down the freeway on 33s and 35s. They don't look like they have much for issues. I'm not looking for this thing to get great mpg. I did some research and saw Edelbrock recommends the 500 and 600cfm carbs. I think I'm gonna go with the 600 since the 500 is for 302 and smaller engines.

[Heredoggydoggy]

I don't think the size of the carb matters as much as the heaviness of your foot!    As for the lift kit and big tires, It's your vehicle--build it the way you want it!

Cool!  You may need 600 cfm to push those big tires down the road!     I think 600 cfm is the maximum flow.  I don't think you get that running on the front 2...
