It could be a T-18 or an NP435
This should help you identify it.

well, it could be a heavy duty 4 speed with the low first gear. Or it could be a toploader 4 speed, precursor to the 3 speed with overdrive series.. less likely. I don't know if those transmissions were ever offered in the trucks.

Here's a guide that may help:

You can do quite a lot with the engine. Read some of the sticky's at the top of the thread list in this forum, and follow some threads. There are simple, low buck things to get you started, with exhaust work, ignition system upgrade, rocker arm swaps, etc.

Just found out it is a NP435. I havn't seen the truck yet, but is the gears set up like a T18? I mean do you shift the stick the same? 1st-up, 2nd dn, 3rd up to the right, 4th down to the right. Reverse all the to the right and up. This is for a T18, does the 435 shift like this? Thanks

That thread will give you some ideas about cam and carb combination's with DD projected guestimates on hp/tq at the flywheel.

Sit back, do a lot of reading, take notes.

Reverse is over and up on the BW, over and down on the NP.
If you go to Fordification.com, Keith has all the numbers decoders there and you can see what tranny, rear end ect. your truck left the factory with. If you are going to build a bumpside that site is gold.
Your truck might also have a Dana 60 instead of a 9 inch. Some stickshift 67s did.

The early T-18's such as is in my 74 F-350 have reverse in the over-and-up position, somewhere in the late 1970's it was changed to the over-and-down position as in my 84 F-150. I dunno why they made the change.

I have a 67 with a NP 435. I rebuilt the trans last summer and I have a lot of respect for the thing after having taken it apart. The bearing areas are huge, the linkage is simple and direct, and the casing is super rigid. One thing to keep in mind as you spec an engine is that the NP 435 is effectively a three speed on the street. First is a spur cut "granny" gear that you won't use unless you are towing or creeping.
The transmission pairs nicely with the 300 in my opinion because the low, flat torque curve compensates for the wide ratios in the gear box. But, if you want something that shifts fast and plan on racing the truck, I am not sure it would be the best option. If you plan on using the truck for work, however the NP 435 is one of the best transmissions I have ever used. The very low first and reverse gears make it very easy to do things like pull the slack out of a log chain, or back a heavy trailer through a tight squeeze without smoking the clutch.
Good luck,
Oh, and I bounce back and forth between this site and Fordification all the time. There are a lot of guys on that sight who have spent way too much time with 67-72 Ford trucks and, unlike a lot of other sites I have looked at, actually know what's up.

Right you are. I am always thinking in terms of 67-72 trucks and forget that fact, also the later ones have a synchro 1st too I believe.
Yes these trannys are tough, they are basically farm truck transmissions. I love stickshifts but those old farm truck trannys will wear you out if you live in the city.

I'm enjoying both the T18 and NP435 in my trucks. After shearing off the shifter locating pin in the T18 top housing however, I'm thinking the NP435 design may be just a little bit better.

I've seen where a couple of T18's known to me have broken in the same place. Since it's cast, and also where a steel cup threads on to keep everything in place - it's not an easy fix.

i thought the T18's were the non-syrchro, and the synchro model was the T-19 that came later. i could be wrong though.

and as for the NP435, thats a bulletproof tranny! i did manage to bring one down, but it was only a synchro failure after much abuse (read shifting with broken clutch linkage). it took said abuse for some time, was driven properly for another year, and finally 2nd became a non-synchro gear. darn thing had the right to break! and it still got me around in that condition for a month till i got my car dug out of the snow.
only other 435 problem i've seen is popping out of 2nd while rock-hopping abusively. and that was likely just the shifter's momentum pulling it out.

Well just found out that the eng is a 240. Thanks for all the info guys. I think I should have some fun with this truck. The other one has a 360 in it but there is no substitute for a manual shift regardless the size of the motor.

the owner has told me the truck will not shift into 2nd, but 3rd and 4th work. is 2nd bad or is it because 1st is not synched and he tries to shift into 2nd?

I would agree with Alfred Lord Tenniscourt, I love the NP435 in my '84. Unfortunately thats probably one of the (many) reasons the truck has been overloaded more than a few times...
I've also noticed that if I try to down shift into 2nd while still moving, it doesn't seem to like to go into gear. Doesn't really bother me too much as I really don't drive the truck into town all that often. It could also be due to the fact that not as many people know how to downshift (or shift at all, for that matter), especially with a granny low.

well the truck should be delivered today. it will still be a couple of months until i get home to actually look at it. maybe that is what the owner was talking about. down shifting to 2nd. i was thinking he was talking about going up in gears. i know on a 70 i used to have with a t18 i went by sound to down shift the gears. didn't have any gauges to go by.

2nd gear synchro is probably bad. These trannys certainly aren't made for speed shifting but it really should downshift into second without too much trouble.

The non-synchro granny gear requires either stopping completely or a quick double-clutch technique.

my truck has a newly freshened up NP435 with a new synchro on 2nd and it has it a bit hard to shift into 2nd while moving, especially when cold. a good double-clutching gets it in just fine. and once it's warmed up it's fine. running 80w90 in it right now, wondering if 75w90 would be better.

75-90 synthetic ( I'm using Mobil 1 ) makes it a whole different trans.
