Whats involved in putting a 2F in place of an F motor? I want to replace my tired F with the 2F from my FJ60. I also will be putting a 420 mated to the 3pd t-case. So any help with that would be great. Like what adaptor do you recomend and anything to look out for. <IMG SRC="smilies/beer.gif" border="0"> <IMG SRC="smilies/beer.gif" border="0"> <IMG SRC="smilies/smile.gif" border="0">

no problem, your 2f will bolt to the f bellhousing. all your f stuff will bolt on to the 2f (in/ex, alt, ect)

thats what I am running <IMG SRC="smilies/biggrin.gif" border="0">

the mounts are different but the bolt holes are the same. I use the 2f mounts because they are way better than the pos round ones. when you remove the round ones you will probably notice that at least one if not both of them are broken. <IMG SRC="smilies/smile.gif" border="0">

i put a 2F into my 71. the 2F will go in fine. either mount will work. you might wanna think about whether or not you want to use the electronic ignition of the 60 series or the points system of the F. you either get points pain in the ass, or some rewiring. this might also be a good time to consider an HEI (mudrak makes a good one) while you're in there. there's also some water pump/themostat issues. On the F i had there was no thermostat and no wiring to the pump, on the 2F i got, there was both. instead of fighting the wiring (i hate electrical) i just put the F water pump on the 2F, no problems after 4 years of hard wheeling up in the sierras. the 2F also has some of the accessories (alternator, power steering pump etc) on the opposite side as the F. depending on what you've already got setup to run off those accessories you might want to keep the old F accessories.

thanks for all the good info. what clutch will I be using if I run the 3pd wth the 2F and F bellhousing? and will the 3pd be in the same place it is now so I won't have to do any driveline mods? <IMG SRC="smilies/beer.gif" border="0"> <IMG SRC="smilies/beer.gif" border="0">

Why bother with the HEi dist? When the stock dist that he has in the 2F is electronic and waterproof? I have never understood this modification on a late model 2F. You would be loosing a beter Dist by switching away from the Electronic toyota dist. If you don't believe me get a HEI wet....... <IMG SRC="smilies/frown.gif" border="0">
(Although I do like just about everything Mudrak sells <IMG SRC="smilies/biggrin.gif" border="0"> )
As for which clutch to use it should not matter. Both transmissions have the identical 10 spline input shafts. And if you do the SM it will not matter either. All you have to do is run a chevy 11" disk instead of the LC disk.
BTW the three speed tranny is not a great tranny. Either opt for the SM or run the 4 speed.
Everything should mate up the same. Driveshaft changes should not be necessary....

mace,
only reason to run the HEI is hotter spark. the late model 2F electronic is not water proof, just water resistant. my wife has a 60 series that routinely has water issues, even with the rubber booty securely fit on the distributor. not much different from the HEI in that regard. i agree with your comments on the 3 speed vs. 4 speed tranny and strongly agree with idea of going to an SM420. the lower gearing is a great asset on the trail. just throw in the 420 and get a cheby 11' clutch disk, you'll be all set.

forgot one other little problem. the fan on the 60 motor is a clutch fan. its longer than the metal assembly on the F. it might require some movement forward of the radiator for proper fit it if you wanna use it. some folks like the clutch fan for water crossing issues. i myself have broken a clutch fan badly at fordyce in the first water crossing, so i'm unsure of the benefit. of course it didn't help that i was running through the water like i was on the freeway trying to catch up with the group i was with.

no prob, the early 2f's didnt use a fan cluch <IMG SRC="smilies/smile.gif" border="0">
or if you are running everything off of your f, the f pump will bolt on too.(as long as the 2f dosent have a oil cooler)

Bringing this subject up since swap time is coming soon <IMG SRC="smilies/biggrin.gif" border="0">

What needs to be done in order to run the 2F distributor in the older ('72) chassis? Anything special?

Let's talk alternators now - Should we just extend the wiring from the '72's harness to reach to the opposite side so that it will reach the 2F's alternator?

Okay, another question: Anyone successfully disable the fuel shutoff solenoid so that we don't have to bother wiring that crap too? <IMG SRC="smilies/rolleyes.gif" border="0">

We plan to do this swap next weekend, and we're trying to figure out all the little details now. We won't have a lot of time for head scratching <IMG SRC="smilies/tongue.gif" border="0">

Thanks guys!

Jim-

1) why not keep the drvers lower location for the alternator. 1972 you can skip the smog pump right? Mounts from F should bolt onto the 2F.

2) the idle cut solenoid can be pulled out, a charge (12v) put to it and the pin cut off with a small saw blade.

Hey Rick,

Nope, we're getting rid of the smog pump...Duh, why didn't I think of bolting the alternator up to the old location? <IMG SRC="smilies/biggrin.gif" border="0">

Thanks for the tip about the idle solenoid too, that will work great.

Any ideas on the best way to wire the 2F's electronic distributor into the '72's wiring harness? The 2F is the one out of Coffey's '87 wagon, if that makes any difference.

Thanks Mr. 45 Wagon Man <IMG SRC="smilies/smile.gif" border="0">

I'm thinking that I can take the FJ60's entire ignition system (coil/igniter) and swap it into the FJ40, grabbing the power source from the 40's IGN wire right off the switch. Does this sound about right?

I doubt the 40's coil is up to powering the 60's distributor, and I know the coil/igniter out of the 60 is in good shape. Any comments or sugguestions?
