Pre-Emmissions?

What year did Ford start putting the emmissions stuff on Broncos? I think it was the early 80's but I'm not real sure.

Also, I'm selling my CJ7. I'm trying to decide what to buy next. Another CJ, early Bronco, or Scout? Right now, I'm leaning toward the Bronco 1st, Scout 2nd.

Anyone know a good wed resource that will tell me about what specific drivetrain came on what years? Which trannies are good, which are weak?, ect...

Thanks,
Joey

Re: Pre-Emmissions?

My guess is '78, but I know for sure that they were putting it on in 1980.

I don't know for sure what website to go to which willl specify what drivetrain is good and what drivetrain is weak, but thats why this board is here [img]/wwwthreads_images/icons/tongue.gif[/img] !! What do u need to know? I can tell you that the Ford ttb is weak ('80 and up Ford trucks) and that Dana 60 is stronger than the 9" which is stronger than the dana 44. Also, you want to avoid the AOD as compared to the C6 tranny. But, what do u need to know? Fire away.....

Re: Pre-Emmissions?

My 79 F150 had cataletic converters- well it used to anyway. I had to call like five different muffler shops to find one that would bend new exhuast for me. When i did find one they told me the reason they could work on it was because 79 was the first year the ford had cats, and ford only put em on like half the trucks that year, so nobody would be the wiser if i took mine off. Dont know if its true, just what some muffler guy told me.

Re: Pre-Emmissions?

Are you talking about the early (66-77) or late (78-96) Broncos? The first emmissions including catalytic converters was on the 75.

For the early Bronco drive train you don't have much choice in stock form. Either the 3 spd manual or C4 (some say C5) auto available in 73-77. Both are strong enough for a stock Bronco, but as you start gearing down and putting bigger tires on you might want to look at swapping out that 3 spd. The NP435 w/ granny low is a good choice and plenty strong. For links on Bronco trannys check out my WebMap:

For a good year by year history of changes to the early Bronco check out the Bronco Graveyard's site at:

Re: trannies

The free Advance Adapters catalog has some good info on transmission. Mine arrived only about 5 days after I ordered it online.
