And my last little project, had a Con-Ferr seat I got from Mark A. recovered to match my coral seats.

Coral? You told me they were Texas burnt orange? :hhmm:;)

As good as those seats look in the photos, they look even better in person. Good work Sir! :cheers:
 
Hey - hadn't checked this thread in a while, just been enjoying the truck since the conversion. Here's a pic of the 80 steering wheel:

Will be starting on the aluminum tub soon, will probably start a new thread for that ;)

Does Cuz still have that 80 steering wheel for sale?
I guess I could just ask him!

Hangin' in his garage, but the price will be high. :lol:
 
quick question:
the difference in performance on the highway between the FE and the F? night and day? decent? mediocure? not a lot?
the fuel economy increase doesn't seem that great (yah, every bit helps) and i have 3 3FE engines sitting here in great shape and 2 trucks i could put them into but is it really worth the effort?

the one truck is a 1991 FJ75 with the original carb'd 3F and the fuel economy at 50 mph is very decent but the power sucks. my wondering leads towards highway performance, since i could add a turbo to the FE setup ...

more curiosity than anything else.

don't get me wrong, i can see you had fun doing the swap ... are you happy with the results? would you do it again or would you go stroker?

The main difference is the power curve, on the highway a 3F can run at 4k all day and be happy where you are redlining a 2F. The injection adds to the drivability not dealing with a choke, and the obvious off camber advantages not having to flute the throttle to keep fuel in the bowl. I went from 9 MPG to 16 MPG with the same gearing and tires, so that was quite a difference on my rig.

Now that said, carbed 3F to 3FE is less change other than what I mentioned and the turbo options. If you've got the parts you're really just out the wiring hassle :). I had a good running 3FE I picked up cheap, if i had the later 2F or were I collecting parts I would have done a stroker ;)

BTW: People are always citing the extra low end torque of the stroker, I really haven't noticed a difference in real world driving from my old de-smogged 2F w/ a header torque wise.

That's a remarkable improvement, with no change other than the 3FE swap. Are you running 4.11 gears?

It's really noticable going from the 3FE to the 2FE in a 62. Towing, taking hills on the highway and pushing tall tires are all much more relaxed. Mind you, with the auto, "low end" starts at >1500 rpm.
 
that is quite the improvement.
i have driven a number of 2F engined vehicles over the decades and i have to admit the 3F seems like a dog in comparision but the fuel mileage is quite a bit better.
maybe a stroker is the way to go for me. then again maybe i just need a carb rebuild??
i like the idea of better performance but in the end it is drivability and comfort that i am after. i don't need a rocket that is loud and sucks fuel, a nice throttle response with fuel economy would be the goal.

thanks for the response.
cheers
 
.... a nice throttle response with fuel economy would be the goal.

Wayne, what kind of fuel economy are you hoping to achieve? My 40 has a stock California smogged 2F, 3.70 gears and 33" tires and I typically squeeze out 17-18 MPG on the highway. That's pretty close to Tucker's transplanted 3FE, although there's no contest performance wise--3FE wins hands down.
 
Just to add to what I've said, the manual transmission really wakes up the 3FE. I'm running my stock h42 and 4:11s with 33x10.50s and have plenty of low end and extra legs to pass someone on the highway. Mine is de-smogged so I'm not sure if that makes a difference, but the stock 3FE with the auto in a 62/80 is a dog.

Is your FJ75 a manual or auto?

You have to take what OMA says with a grain of salt, I've never seen anyone get the MPG numbers he gets (and I've confirmed) in his 40 or 80 :frown: He really takes the slow lane ... haha :flipoff2:

Tucker
 
well, i am getting a solid 15 mpg US with the carb'd 3F, if i could get 18 mpg US and have a bit more reliable performance to boot then i would be happy.
i drive roughly 55 mph around here so RPMs are low although i do haul a load once in a while:

I detect a note of envy. The highway 17-18 MPG I reported in the 2F powered 40 is achieved driving a steady 62 MPH on country roads, but it's not an aberration. I do it all the time. If I drove like you I'd be lucky to squeeze out 10 MPG. ;)

Are we still grabbing a Happiest Hour pint this afternoon?

Nice truck, Wayne, but you missed a strap :D

Tucker's conversion is sweet and performs really well.

Uh huh. You and I both know that improvement had nothing to do with the 3FE engine swap.

The real difference...Orange Seat Covers :D:beer:
 
In case anyone out there is looking to do this swap, I used the stock 2F passenger side mount:

1000000165.jpg


And 3F DS mount slotted 1/4" towards outside:

1000000171.jpg


This effectively centered the engine exactly where a 2F would sit, I was not worried about shifting the motor towards the PS because I've got the short booster on my '76 that allows plenty of room for the Master to clear the intake runners:

1000000172.jpg


Notice this way there is plenty of room for the stock rear hook and fuel hardline to cross the rear of the head:

1000000167.jpg


Couple of pics of the stock 2F bell housing and transmission mounts:

1000000169.jpg


1000000177.jpg


The only thing that's going to be tight is the front exhaust manifold next to the mini-truck PS box:

Thank you for your information.....:clap:

Sorry to dig this up, but I was re-reading @lelandEOD threads and found your link...
Frame brackets are factory 40, yes?
You put the PS 2F bracket onto the 3FE block, and then used the old style, round rubber mount, eh?
DS has the 3FE bracket on block + old style round rubber mount as well?
Do you recall if the newer, rectangular rubber mount would fit?
My DS round rubber mount has separated and gives me some clutch chatter when starting out from a stop. Trying to figure what to replace with...
 
@tucker74 thanks for the info. Just read your thread as I'm considering a 3FE upgrade in my 1974 FJ40 w/F engine. I'm looking for more HP and better top end speeds to get me out of Metro Atlanta into the N. GA mountains and into the trails. After having done the swap many years ago now, any additional thoughts/roadblocks or land mines I should be on the lookout for? I've sourced a 3FE engine for $500, everything looks great on the inside (someone did regular oil changes!) and I'll need the ancillary parts, harness etc. Any additional thoughts or encouragements would be welcome. Tks again for documenting!
