Need Ford help.

[Hank Chinaski]

I'm not a Ford guy, but I do own a '71 bronco.

What auto trans(s) will fit between my 302ci sbf and the dana 20 transfer case? It's currently got a 3 speed in it now. What else other than the trans will I need to do the swap?

 

[Blazin]

Put a chevy gear train in it :derplol: Find yourself a C4 and you'll need the adapter kit from the trans to transfer case, maybe ebay or new they go for around $500.

I'm actually "really" close to doing that. I've got a 468BBC/T400/NP205 that I could put in there right now... and prob will before it's all over... dunno if the axles will hold up, but I need an excuse to get some more rockwells anyway.

Top loaders? Is it coming to the GTG???

not anytime soon lol... it's on 33" TSL's now and rides like crap, no heat, or wipers and still need to get it licensed to go on the road. It'll be a year or so before I can get some 2.5t's and wheels/tires... I've got a set of 54's here, but I prob won't run them on this, I prob won't go over 40-44's or so, I may just one ton it and keep it around 37-38" and a lot more streetable.

the pic isnt' mine, it's one on 53's

There is a C4 that came in some of the early Broncos, but they are hard to find. There are differences in the cases, in regards to where the dipstick goes. Some go into the case, others go into the side of the pan.

Why go slush box? If you get the longer 3-speed adaptor housing intended for 6-cyl Broncos (170 or 200ci I6) or the Advanced Adaptors reproduction of it, then you can install an NP435 four speed from a '70s Ford full sized 4WD pickup (with a married TC setup, some of them had divorced TC's and 2WD style transmissions). Those NP435's are a dime a dozen. The six cylinder adaptor is longer than the one used in V8 Broncos. It'll bolt right up to the Bronco D20 TC (which is a D20 version unique to the early Bronco and a few 4WD F100's). Another option is to run the NP435 4-speed with the NP205 TC that was attached to it when it lived in the donor truck.

I wish I still had my 289 powered '66. Was uncut, with no rot when I sold it to buy an ex-CHP 5.0LX Mustang. That BBC will be a lot of work to swap in, and not needed unless you're running rockwells with huge meats. If you want a little more muscle, a 351W/5.8L goes in pretty easily. The stock 9" rear and D44 front (1971 was the first year of the D44.......before that they had D30's) will be fine with a mild small block and reasonable tires, but won't live long with the rat and huge meats. A 4WD small block application C6 auto is a good way to go (with a 289/302/351W) if you really wanna run a juice box. You can run that with an NP205 TC (all out of a '70s Ford 4WD pickup). You can also run it with an NP203/NP205 doubler setup. A BB application 4WD C6 would be fine if you want to shoehorn in a 460 too.........but again you're going beyond the axles.

thanks Aaron. Lots of good info in there.

disability is the main reason for the auto. My left leg is iffy sometimes.

I hear ya on the axles and will most likely be going up to at least one ton stuff within the next year if I don't skip it and go up to 2.5t rocks. I don't think I'll go 5t (at least on the bronco), but keep it "reasonable hell for stout".

this was the project that I got a little stalled on and traded most of for the bronc:

and here's my bronc:

That was a cool looking M715 (and I think I spy a CUCV pickup next to it). You've got a strong starting point in that Bronco too. I understand your need for the auto. Sorry to give you grief. I've got my prejudices.:derplol:

Best bang for the buck for you with an auto in that rig would be the SB C6/NP205 setup. Sronger than the C4, more upgradable, and more able to handle serious power in the future. You'll be able to sell the Bronco D20 TC for decent money. Run the C6 with that 302 (yours was the last year before they were detuned.....making the '71 the "golden year" for STOCK Broncos as that was the first year of the D44 front) or with a 351W. Use those axles for now, then upgrade to D60's when $$$ permits. There are various cheap ways to upgrade that front axle to discs. Use a hydroboost setup for much stronger brakes. Run an NP203/NP205 doubler if you need deeper reduction. That 'need' depends on what tires you're gonna run.....what gears you'll have in the axles, and what type of wheeling you'll be doing. Lots of options......

Here's what fulfills my old iron needs now. Old diesel Ford 4WD truck (with a C6), and older IHC Scouts. Also have a 4-door 3/4 ton 4WD IHC pickup that's a LONG term project. No time or money right now......so they sit. My beloved diesel has died too. Killed a piston on a grade last June (on the way to the PNW GTG). Let the temps get a smidge too high. Still made it 100+ miles back home...

Holy shiite. Another IH fan. Me too :yup:

NICE short bed 'C'-Series Travelette!!!

I was looking for one of those when I got my 1971 longbed 1210 Travelette (four door IHC pickup for the non-Binderheads amoungst us). I like their looks better than the 'D'-series trucks like mine. My rig (22' long green pickup in my pics) has a 392 V8, T34 IHC/Fuller OD five speed manual, divorced NP205 TC, closed knuckle "big ball" D44HD front (same 'balls' as a closed knuckle D60 as found on M715 trucks and some Dodges), and D60FF rear. Also has non-functioning AC. Somebody went all out in 1971. I still have the lineset ticket for the truck. The engine's down with a blown head gasket. Blew about 1/2 mile from my 'new' house when we moved. Steamed the rest of the way home....

Going to swap in a C&C width GM 14-bolt FF dually rear and a dually application D60 front someday. Aready have the 14-bolt. The D60's the spendy part. The closed knuckle fronts (for those that don't know) only give 19degrees of turning, compared to 40degrees for for the open knuckle fronts most guys are familiar with. That 'big ball' closed knuckle front gives my 164" WB behemoth the turning radius of an ocean liner....

Mine came from Sacremento, and I am using the 392IC, 5 speed direct, Watson over-under, and NP 205. Axles are Spicer 70 front, Eaton rear, with 4.88 gears. 3 inch wide drums all around. I am not pleased with the two transmissions, and planning a 4L80E swap.

 

[Eccentric]

Is that Watson O/U like a Brownie? Why don't you like it? I have a Gear Vendors OD behind the TC in my diesel. Damn GV died. Not robust at all. Where are you? Let me know when you pull that Direct 5-Speed and Watson setup. Did you get that Travelette from Jeff I, or Chad?
