1976 2F swap into 1966 Fj40

[kindoflikerambo]

Mudders,

I am seeking knowledge on a few idiosyncrasies of the swap mentioned in the title. Yes there are many considerations but I'll keep my questions bulleted and concise. First a few important considerations:
-I pulled the stock 1966 1F and have all the engine mounts and goodies. Engine ran great (only had 89k original miles) but I'm sick of adding lead additive and the 1bbl carb, while the MPGs are the best of any Cruiser I've driven, the power trade off doesn't quite suit my needs. Anyone looking for a complete running early 1F let me know and we'll make it happen on good terms for both parties.
-I have a complete 1976 2F stock with the exception of a brand new never installed Non-USA later OEM Aisin Carb.
-My 1966 fj40 is stock.

Questions:
1) Will I have height clearence issues dropping in my 1976 2F into my engine bay? If so how do you solve? Swap engine motor mount brackets? Air cleaner heights? What have you observed (not heard)?
2) How will I solve my (early early) style accelerator to mate with my newer carb? (I purchased a complete factory 1976 2F accelerator linkage package and a (mid-later vintage) style orange boot accelerator pedal but would rather seek options for ease that people have observed (not heard). Is there a good cable option that would make my life easier?

If you have read this far thank you for you time! I have conducted a lot of research over the years in anticipation of this swap and there are many rights and wrongs and opinions. I am hoping for first hand observations or knowledge from the sage Landcruiser omnipotent pros who know! You know who you are out there and thank you for all the knowledge you have imbued on us Cruiser folks!

Once I'm finished with this swap I'll have some early Landcruiser drive terrain goodies. Have some other odds and ends I'll be losting to clean out too so let me know. Not trying to make a buck. Trying to keep the quality OEM parts in circulation for eveyone to enjoy!

Thanks again!

We're fixing to do a similar swap down in the Bitterroot. An 80something 2F going into a 69. I'm not sure on the major differences between the 66 and 69 (other than chat related) but I can't think of many, and nothing that can't be worked around.


Usually it's the bolt ons that make things a headache, manifolds, putting the carb in a bad spot, but you shouldn't have a brake booster to be in your way.

Put a '83 2F from a 60 series in my '69, I found:

1) No height issue but you will need newer style engine mounts.

2) A 1976 accelerator set up has the cable to a bell crank to the linkage to the carb that works.

Show us some pictures of what you have.

Here's the bell crank from a '76 that you will probably need, believe it was originally zink coated but I painted mine. You will also need a return spring fitted to it to keep the carb from getting stuck at full acceleration...DAMHIK....

Had to go back and check my build but looks like I survived, it was in neutral and I was able to turn it off before it blew itself up.

Put the battery back in, poured in a couple gallons of gas, turned it over a few cranks and got gas but no ignition....reconnected the distributer to coil wire I've been removing to drive by starter...

Gave it few more cranks and it STARTED UP AND RAN!!!!

DANG how awesome just idling along nice and smooth like a sewing machine...wow!

Tried to post a video but the best I can do are these crappy screen shots of its glorious smoky first startup in over 21 years, sure its different motor and running gear and all.

Still have some things to address most...

I'm planning to install a booster but I'll inquire as to those clearence issues in another post! I think I have pictured evidence (here on another mud post) of what I'll do for that Haha!

Just looking for answers on 1) 1976 2F clearence concerns in a 1966 engine bay and 2) accelerator solutions to convert to the newer non-us spec Aisin 2F carby on this post. Thanks for your reply though! Let's wheel sometime!

It's not much help, but I'm running an 83 2F in my 74, with a non-US spec carb. I used the 83 manifolds.

If you need to pull specific measurements I find myself in Missoula quite often.
Or in Stevi.

Thank you so much for this! This answers my first question of using the engine mount brackets that came with my 1976 2F versus robbing my old 1966 1F engine mount brackets. I read the hole sizes for them were differnt but thanks for confirming I won't run into height issues (because of the mounts). I'll take some pictures when I'm home this weekend of my carb, firewall, existing pedal, and the goodies I acquired for this over the years to make it work.

I have newer late style 2F manilfolds but my "early" 2F manifold that was from the '76 donor engine was in the best shape. I hope this will work for my newer carb!

So cool to see another oldie Cruiser out there with a nice power terrain setup!

 

[rkymtnflyfisher]

It really shouldn't be very difficult, the biggest hurdle may be not an issue with carb/brake booster interference. Using some stuff from the early engine to mate things up for the new engine should solve most problems.

Making the carb work with the existing setup shouldn't be overly difficult either.

 

[rkymtnflyfisher]

Do you have a plan for the air cleaner for the non-US carb? The carbs are different heights I believe.

 

[brooklyn]

I have a 2F in my ‘67 — I ran into issues with the brake booster and master cylinder fitment — I have disc brakes at the four corners. We found a small brake booster, but didn’t feel the have me the braking I wanted. I am now installing the small CityRacer booster and a new master cylinder. I think I can just squeeze it in. Hopefully that will do the trick. Also stayed with cable for accelerator using a bell crank. I sourced it from SOR.

 

[igotta40]

I put a 75 2F into my 74 FJ40. I updated the engine mounts, used the 74 intake, and the header was a straight swap. Also used the 74 air cleaner and I think I have a Aisin carb for a 71 on it. The throttle linkage required a little help from MacGyver. I used a throttle cable from a mid 80’s Corolla and made my own pieces to connect the carb and pedal.

Super helpful info! My plan is for discs. I don't know if I'm in for front only or all the way around but I saw a thread about it a ways back about how to cut and configure the ribbed firewall to make it work. While my 40 is stamped a 1966 I suspect it's actually a 1964. I don't have the cable style bell crank that people mention as theirs being "early" mine is a bunch of linkage parts. No cable. Still looking for a solution

Thanks for the reply! Any pics of the MaGuyver Corolla accelerator setup?

This is what I have read as well about fitment issues on an early 2F air cleaner in an early model engine bay. Read that a later style air cleaner is shorter. I'm hoping someone can provode some hands on evidence of this before trying to buy a layer model 2F air cleaner.

Very helpful! Awsome configuration! I replied to your pic with drawn arrows in the photo of which direction I assume the tension increases when you apply the accelerator. Is this correct? When it ends at that point where does it hook to the carb and which way does the tension continue? Thanks for posting! Showing me anytjing is possible with a lottle creativity.

Attached are some old pictures of my setup with a blow up from SOR. On the SOR image I attempted to draw the direction of tension while applying the accelerator pedal before the sandman takes me away this eve. When I get home this weekend I'll send better pics behind firewall now that I pulled the engine a couple weeks back for it's new heart.l transplant. I found one I took with the beaty rib showing a friend after the pull but it's a grainy picture.

Let me know if anyone knows the direction needed for the non-us spec Aisin 2F carb from (probably) the mid 1980's. I would like to keep the inside of the cab as "untouched" as possible. Engine bay firewall side, clean is good but function over form is best for me! I'll try to get a pic of my carb this weekend. Thanks in advance for everyone's input!
