1978 Bronco...What do you all think

I have the opportunity to pick up a 1978 bronco. Right around 2500 dollars. The body is straight and no rust. It has the 400M, C6 combination. I am looking for a rig to take out to the desert and play around with. Is this a good choice? The reason I gravitated towards this model is that it has the 44 up front and the 9-inch in the rear, what a great combo! It has about 103,000 miles on it. What thing should I be aware of with this model? Any help would be appreciated. Also what size lift would I have to put on it to fit 35's. Thanks for the help.

Re: 1978 Bronco...What do you all think

Nice choice [img]images/graemlins/grin.gif[/img] I don't have to tell you about the rust problems since it doesn't have any. As with all Broncos, the tailgate window will get slow without maintenance. Keep a spare DuraSpark ignition box with you as these are prone to failure. Make sure your driveshafts are nice and tight. Check all the front end and steering components for looseness, especially the track bar bushings. A 4" lift will clear 35" tires and make the truck look like it should have came that way from the factory.

Re: 1978 Bronco...What do you all think

how are the 78's for smog equiptment? Is there a lot of stuff? How will the 35's do with the C6, three speed, rather than a 4 speed. I mean with lets say with 4.10's in the axles will I be taching 4000rpm doing 65 down the freeway?? I am just trying to figure out if I should bid on this thing..

Re: 1978 Bronco...What do you all think

You sure on the RPM's? that seems high for 4.10's and 35's. In any case, the truck is a great combo. You should bid on it. If you get it for anything under $2500, and the body, suspension and drivetrain are in good condition, I think you will have a good deal. Does it already have the 4.10's? If so, you won't really need a gear swap for 35's with that motor.

Re: 1978 Bronco...What do you all think

the 4000 was just a guess. The only reason brought it up was because a friend of mine who is "anti-automatic tranny" said that the rig would be turning high rpms if I changed the gears and ran 35 with the C6.

You'll be fine with 4.10's and 35's.

Check the chart, here

If your buddy is advocating a 4spd over the auto, he should use a different tactic. Both the C6 and NP435 have a 1:1 final drive ratio and will turn the same rpm in top gear.

49 state 78's had only an EGR valve. California 78's and all 79's had EGR, smog pump, evap/purge system and catalytic converter.
with 4.10's and 35's you should be turning 3000 RPM or less at 65.
My 83 F350 has 4.56's and 32" tires and turns 3000 RPM at 60 MPH.
