1969’s build thread

[DirtDonk]

And per your other posts, when you have it apart, might as well clean up the perimeter of the old damper the best you can. To give timing tape, a good place to stick in case you decide to use it.

This is probably the most exciting update of the whole Bronco so far. Got the battery tray in.. ha ha

Gotta have it to make it run it’s an important step

Aluminum and magnesium don’t like being bent, they break, even though they are strong and rigid. The chassis will flex quite a lot which puts tremendous loads on the tcase adapter and bell housing. As the chassis flexes it tries to bend the transmission over the transmission crossmember. The tcase support is quite rigid as well with the 2 frame mounted spring eye bushings that are mounted near the center of the frame. Articulate the suspension hard and add traction from bound up tires the bending and twisting stresses are way higher than the case design was built around. Something sooner or later is going to give up. To alleviate the added bending and raising loads a 3 point mounting system is the way to go.

I’ve witnessed far to many transmissions with the tail housing and/or bell housing broken to not speak up.

I’m hoping your not offended, really trying to help you have a fun, safe, dependable rig that you’ve spent a lot of time and resources building.

ZF/205 going in mine soon, I was planning similar mounts as OP. Do you think a mount designed to only hold the 205 would work? Skip the trans mount? Or just tie them together?

Did you have to drill one of the mounting holes? Weird that mine only has one...why didn't they just slot the second one.

I don’t think it matters how you get there. Just need to have a single point of support with some flex. Solid in the center with bushings at the frame is bad too, it will not have enough give. You need the motor to twist and move with the frame, otherwise your eating the radiator and fan shroud with the fan.

The two holes I used to mount it I did not modify, it lined up good enough for me.

Either or would be fine imo. But if you do the trans crossmember you can at least get the crossmember from BC by calling them since it’s not listed vs fabricating an entirely new mount for the t case.

Is your Bronco really a Bronco if you don’t install these valve covers?

Also turns out I have a 1965 289? At least it’s clean. The guy I got the engine from wasn’t sure if it was a 289 or 302 but was told it was rebuilt at some point but had low miles on it.

 

[DirtDonk]

Always good to find clean when you open it up.

Back in the day, must’ve been a lot of Cobras wearing Bronco bodies!

What are the casting numbers on the side of the block above the starter?

Thanks, 289 casting numbers there also. I was just curious because you never know with a rebuilt engine.

I appreciate the curiosity. I’m not a “engine” guy so I’m not really sure. The guy I got it from did say it was 225hp build from the machine shop but again I’m not sure and have no paperwork to prove it. I’ll just be happy if it runs good.

Went to swap out the spark plugs as a “quick” job this afternoon. Ended up pulling the headers and also trimming the gasket down so I could remove the spark plugs.

The plugs are a bit rich! The guy I got the engine from did have a 6 or 700 cfm carb on it he said ha! Poor little 289! Anyway threw in some Motorcraft copper plugs and put the headers back on.

 

[Speedrdr]

Wow! Trim job definitely required there. What a PITA.

More work on the Explorer serpentine conversion. I went with a Cloyes Street True Roller Timing Set, p/n 9-1138. The Harmonic Balancer from Dampnerdudes is also really nice. Currently waiting on the passenger side bracket to come back from powder coat, and I’ll be ordering the Wild Horses Saginaw conversion bracket to finish it off. Everything has gone fairly smooth during this conversion.

I installed the Explorer serpentine Saginaw conversion bracket from Wild Horses. The bolts it came with were one size too big for the bolt holes on my head. Popped over to the hardware store and got the correct bolts and it went on no problem. Very nice bracket!
