Timing Question

[Tommy21]

Thanks for all the input, I figured it out!

The bronco has a newer balancer that had two sets of timing marks... He marked the incorrect mark (clockwise rotation and counter I believe) And being in work clothes and a slight rush.... I didn't verify. When I made it home, I cleaned it, found his mistake and re marked on the correct side.

I took it back to smog today (different tester) and it passed with flying colors. To answer the questions regarding the two year smog time limit (I purchased the truck about a year and a half ago, and any title transfer requires a fresh smog independent of the two year renewal).

CA smog is defiantly annoying but not nearly as bad as I anticipated. My truck runs very well, and is mostly stock (with the exception of Smog compliant ceramic headers, magnaflow stainless exhaust and CA smog cat), and it barely made a dent on the emissions scale. The tester even commented multiple times about how clean it was running.

Given the axel and brake benefits of a 76/77, the smog doesn't bother me (other than not being able to coyote it).

Thanks Everyone!

Congrats. Glad it's passed, and also with so little on the scale.

Don't know this for a fact, but I don't see why you could not Coyote it if you wanted.
It's a newer motor of the same rough displacement, so kind of qualifies in that regard. Just can't use older spec motors, or those larger than available from the factory as a general rule. But newer and close, with much less coming out of the tailpipe is not always frowned upon.

A Coyote (maybe with 5.0 decals instead of any 5.2 listings?) with all the smog stuff from a later model donor that passes the visual and sniffer tests and it could probably be passed and certified by a referee.
But that means no crate engines. Has to be from a donor with a known smog compliance level.

Of course, then you can run into the same issues that others have run into with Ford EFI versions of the 5.0 Windsor family engines. If it's out of a vehicle with dual exhaust and dual, or quad cats from the factory (such as a Mustang) then you may be forced to run dual exhaust with however many cats that required.
Adds quite a bit to the expense, but duals is likely how most Coyote owners wanted to run the exhaust anyway. Me, I'm still a single exhaust kind of guy, but lots of people still like duals even on Broncos with tight quarters under there.

Or have you looked into it already and found it's not a friendly Coyote upgrade environment yet?

My balancer ring slipped one time - when I turned the engine off, the ring kept spinning. Ziiiinnnnnggggg.....

Hey Paul,

You may be correct, but the thought of the unknown and headaches of trying to get the referee to okay it makes me hesitant. As much as I love the truck, I’d just get a 1975 or older where I know I have nothing to worry about. For now, the old 302 pushes it pretty well.

I'd fix it with this.

Best idea in here. lol

My dad has a 1978 Corvette that passes smog as a 2001 Camaro. It had to be verified by a referee and then they put a sticker under the hood.

If you want to put a coyote in a Bronco, you would basically need to find a stock mustang or F150 with a coyote and swap everything in (engine, emissions, exhaust up to catalytic converters, gas tank venting, and possibly even the transmission). It would be a giant pain in the rear.

I regret eliminating the emission stuff on our '77. Even though we don't have testing here, a Bronco with all the emission stuff intact is worth a lot more money.
Getting performance by correcting the gear ratio would have been a better investment.

Finding one the stuff intact and the smog check was the big reason that I went with a pre '76.
