Finishing touches for Baja. Colorado representing!

Very Cool!... Showoff!

I've been updating the ignition trigger system so I can ditch the MSD 8pt distributor wheel and move to a proper 36-1 crank wheel. It's been a lot of measuring, CAD work and cutting metal, but it's turning out nice.

Admittedly, I am clueless as to what you are doing technically, but it sure does look nice!

[Digger]

Many fords since the early 90s used a 36 tooth tone wheel mounted on the crank, commonly found with distributless ignition (EDIS) One tooth is deleted to help the computer find TDC#1

The system works very well and is straight forward as there is a tooth passing the sensor every 10┬░ of crank motion. As a result, many aftermarket and homebrewed EFI systems have adopted it.

Since spring has sprung, I've been tied up with some yard work, sprinklers, and installing a swamp cooler. I've been on a couple local trail runs that make me think my 33's aren't going to cut it out here. So, despite the fact the truck still isn't running, I've started the transition...

These went on sale. They are warehoused & sold close to my work, and he's delivering them Monday. He's also got a line of aluminum beadlocks too.

I *think* I've built in enough room for 37's.

[Kinder]

37s are the new 35s, youΓÇÖll love them. Are your geared deep enough?

[Gunnibronco]

I've been chewing on the gearing issue for years.

I'm on 3.50s right now. I was running a NP435 & 33's, and they got off the line ok, cruised down the highway at 2200 RPM. Performance was marginal, but acceptable at 8000' (now living at 4700'). The low 1st in the NP made offroading decent, otherwise the 3.50's wouldn't have worked.

This is convoluted, but here is (was) my plan. With my Atlas 4 speed's 11.7:1 low/low, crawl ratio is not an issue. My considerations are getting started off the line & highway cruising RPMs. I'd like to keep my gearing as high (strong) as possible. 4.56's with 33's would give me use of the ZF's OD (2300rpm @ 65). I originally planned to install 4.56's and run off the rest of my 33's. 4.56's, 37's, & OD will not work on the highway with my 302 (2065rpm@65). But 37's, 4.56 gears & 4th gear (1:1) put me at 2700 rpm @ 65.

I have a 9" center chunk with 4.56 gears. My current plan is to install it and run it, and see how it runs (not using OD gear). We'll how it gets started in 2nd gear. And then make decisions from there.

My seemingly weird plan revolves around the 351 GT40 lower & AFR heads sitting in my garage. I still plan to build a 351 stroker that will make OD usable again. Of course by then I might be on 42s & one-tons.

Bronco creep is real. I'll post up once mine is running and let you know how it's looking with a stockish 351w, 4.56 and 37's with the OD. I suspect I'll love it on the flats and shift lots on the hills.

You and I define Bronco creep. Once this is done, I won't be doing much more for a long while. Any project I do will not involve shutting the truck down for long, if at all.

I think you are geared right for your 351. Seems others are built similarly and doing fine (Digger, JD's on 4.10s but not doing much on-road driving).

I think my plan will work. Elevation will help. My concern is getting started in 2nd gear. I don't think starting on the streets in 1st will be much fun. I know it'll get going fine, but require a very quick shift into second. The truck won't be a daily driver anymore, and is going to be a more dedicated trail rig, so it might not matter as much. But there are so many trails so close (within 1 hour's drive), it would be nice to drive, not trailer, to the trails.

[Kinder]

Seat of the pants feel is real, I know the calculator doesnΓÇÖt lie, but youΓÇÖll know what you want once you try it. I just wish it wasnΓÇÖt such a pain to swap gears, BSD has a set of 3.73s in the future to finally get the ΓÇ£feelΓÇ¥ right.

[ZOSO]

All this gearing talk. I'll tell ya one thing. I just went for it. Stuffed in a set of 5.13's. Man is it low. But overdrive is great. 2350 at 65mph on 35's is perfect. I'll run it up to the cabin in the next 2 weeks and see how it does pulling the hills. I chose this deep as I plan to do a trailer in the future and the overdrive in the 4r70w is really low. Could have gone 4.88's and been fine. oh and 4low is nuts. first gear is 10mph at 4krpm.

Can't wait to see it all mounted up! Are you going to try BB's for balancing?

I thought about that, I've read your posts about the bb's but can't remember the specific product or amounts. It would be nice to be able to do it all at home.

[Jesus_man]

I just put on new (to me) MTRs on my beadlocks and used airsoft again with great results. I bought these larger dia BB's this time:

100g per tire is where I am. But you may have to experiment.

[mickphatmac]

Serpentine Mock-up...
Still cleaning up bolt holes and purchasing bolts before it all comes together...
Still need to rebalance to 28oz
Relocate PS reservoir ... blah blah blah

[Strike2]

Looks great Mike!
Thanks for posting the picture, I just added a crossbar to my front hoops and now thinking I should install my "Serp" set up and see if the alt/pump assemble will clear the bar before fully welding. I'm sure it wont clear just by looking at your set up, "JUST MORE REWORK"

I'll bet you're right! Looks a little tight. Might need to go up 2-3"?
I like your "quick disconnect" middle bar, Great Idea!

[ZOSO]

and coil packs. where are you going to mount those?

[Strike2]

and coil packs. where are you going to mount those?

My plan is to cut the coil pack oem bracket and weld it to the cross bar.
I installed a the explorer front serp set up this weekend and was surprised that the hoop bar actually fit. The Alternator has 1/2" clearance and the power steering reservoir just need to be repositioned slightly along with cutting a hole for the main tube to the pump.

[Gunnibronco]

Today, I purchased a 26'x36' steel building.

It will have 3x 8'x10' garage doors on the 36' side, and a man door in one 26' side. It will have 11' wall height, putting the peak as close to 14'11" as possible. My goal will to eventually get a lift. I've had a chance to buy one already, but had to decline. Can't put the cart before the horse, unfortunately.

Permits, concrete, electric, heat, insulation still to come. We'll see how much I get done before running out of budget.

[Jesus_man]

That's exciting! Hope it all comes together for you!

[mickphatmac]

Got a little sumtin sumtin in the mail today...yeah, I know mineΓÇÖs a ΓÇÿ68... (insert devious laugh HERE)

[Strike2]

Those are cool, are they Ford or Bronco specific? I haven't seen those before.

[mickphatmac]

Just the 1....No way I could afford a whole set of Original '66 Bronco 1 year only. This is just a cool find that the guy gave me a great deal on as a wall hanger.
Usually you see them for about $1000 bucks for a set of 4.

[mickphatmac]

More worthlessness...

One of these days IΓÇÖm gonna post an engine swap or something actually worth while!

[mickphatmac]

HA!!!! I told Ya!!!....
I put my 14 year old to work... His 2nd Manual to Automatic swap!

[mickphatmac]

22oz removed!
$50 bucks

I need to put new gaskets on my transfer case and bolt it up to my transmission, put a new transmission filter and gasket on that thing and I might be ready to stab them in this weekend!??

[mickphatmac]

Couple small mods to help the serpentine belt set up...

Made room behind the top pulley for the distributor vacuum.

Made more room by the oil pressure gauge (no A/C).

and of course relocated the ps reservoir.
