Mace it's sounds to me like your doggin' the V8!
I don't think you have to stay with an f/2f engine especially if you want a wider range of power and torque. You can only get so much out of the 6 no matter what.
I've only owned 3 TLC's in my life since 1982 all with 2f's and they worked fine. But they certainly had some short falls. Like HP for example.
I put a Vortec 5.7 in my '84 after much research into modifying a 2f just to get the base specs of the 5.7. The doller per performance. it just didn't make sence.
Maybe you don't need a V8 in a 40, But it makes a hell of a difference in a 60. Both engines work fine for slow lugging type driving. But for halling 700lbs of expedition gear, highway use or just pulling a long uphill sandy track you can't beat the V8.
Yes you can build a 6 just to show it can be done but at that point your reliability and longjevity goes out the window.
Why not just use a V8? Unless your a purist?
And the reliability and durability are right there with the 2f.

Mace said:Gumby, you are dogging the 2F for doing exactly what it was supposed to do. .. Does that make sense???
You going to say a cummins is a bad motor too???
The only reason the 350 is one of the best motors of all time is because they made ABIZILLION of them.. And the aftermarket responded...
In itself the motor is not that impressive. the multiple itterations of it show where it lacks in general..
No. I'm saying damn near any I-6 will do what the 2F will do. I don't think the 2F is that great even for an I-6.
Not enough mains
Weak oiling system
Heavy valve train
Inherant fuel distribution problems of an unequal length wet intake
Intake/Exhaust split manifold design
solid lifters
overly complicated vacuum operated emissions equipment
I have not have Toyota like reliability out of the 2F in my own personal experience. It simply does not compare to other engines for which I base my admiration for legendary Toytoa reliability.

mmmhmmm....the only thing i would like which becuase a problem every once in a while on the trail is extreme angles on the carb, i'd be diggin fuel injection for the 2f.
For me, i dont want to go any faster than i already do on the highway.... 65-70 mph is fast enough for me...Blowing a front tire at that speed with a 2.5inch lifted sprung over cruiser would not be all that fun. True, my truck seems way more stable then it did sprung under i just dont need to drive that fast when i have other friends and loved ones in my hands......i'll stick to my 2f.
And ive never really ran into a power issue on the trail. ive had had the tires smoking on the rocks in quite a few spots.
I have a buddy with 405,000miles (without a re-build) on his 2f and still takes it on 12hour round trips to FLCA meets. I hope to get just as many out of my 2f with regular up keep.
i'll keep the soul in my truck.

Gumby i think this is the only thing we have disagreed on 
maybe im just slower all around

TBI 2F - Megasquirt
TBI really wakes up the 2F. As soon as I finish tuning my TBI system I will post some more info about it. I have kept a very in-depth journal or installation guide. So far, seat of the pants, it rocks. No problem lighting up 35s with 4.56s and stock drivetrain. The beauty of the Megasquirt is the tunability on the fly (it also works on boosted setups, Mace). Stay tuned.

2f
give me a f@#$ing break guys! plz all this 350 vs 2f is getting out of hand allraedy .. were comparing apples and oranges the 2f is the best at what it does reliability,simplicity,and the the ability to get you from point a to z and back again no questions asked thats what it was designed to do in the most remote and toughest regions of the world !!! the 350 tbi - f.i. - or carbed on the other hand is great motor 4 what it is a big truck people moving hauler or a performance motor that will get you down the 1/4 mile in no time, with fair reliability! personaly ive owned vehichles with both motors a 1980 corvette with a 4spd. manual that in stock form felt slower than my 87 fj60with 2f (just kidding) but i really had to modify that 350 with usaul mods intake ,carb , exhaust,ign,port and polish etc. etc. but the seat of the pants feeling of power was there ... and thats what makes the 350 such a great motor guyz .. the 2f"s performance comes from its no frills reliability and toughness and simplicity !
and thats what makes landcruisers of the 2f era so appealing to all of us there realiabilty simplicity and ability to not break unless really stressed out with super large tires and v8 "s stuffed in them! personally i think if you got to have a v8 buy yourself a bronco or blazer or mayby even a surburban of that era and see how well they last through the punishment most you guys put your 2f powered landcruisers through! personaly and again this is my .02cents i think the 2f is the perfect motor for my fj60 she may not respond to perf. mods like a 350 can and she might be a little under powered but she wasnt designed to cruise our highways at 90m.p.h. either! shes got lots of charachter and the day she does call it quits (probably never) ill either rebuld or swap in a 1fz-fe or mayby even a 2uz-fe !
A LANDCRUISER WITHOUT ITS 2F HAS NO SOUL!!!!!!!!

I'm thinking about going to a turbo setup *wet* and eventually converting to this "Megasquirt" TBI system that is so "good." What does it do for the gas mileage? Kick-Ass performance increase? Cost?
It sounds like the 2F is not such a bad motor after all, right HATERS!!! The soul matters more in a truck than the performance that it has, to me anyway.

I bought from some of the vendors on the Megasquirt website http://www.bgsoflex.com/megasquirt.html
I am about $600 into it. I am still fine tuning the fuel map and have not gone through a whole tank yet. I should have some MPG readings in a couple of weeks.

$600 and I have a working system. I may upgrade to a different (wide-band) oxygen sensor to gain a little better control of mixtures.
You need about 14psi fuel pressure for a TBI system. An electric fuel pump is required. I used an MSD pump from Summit that was $90 of the 600.

Thinking out loud here...
What about doing the 3FE fuel injection onto the 2F block? Then do the mods Mark W mentioned in the other thread. Of course one couldn't use the '69-'72 F engine head.

Mark from metal tech did a 2f block with 3fe head. he actually spelled it all out in a post. Probably can search for it.
