Losing the computer

Alright, you guys talked me out of it. On to learning more about adjusting the TBI for a 383. Somebody got the best link?
 
http://www.tbichips.com/
talk to these guys they will set you up with what you need plus they will take the time and help you setup your motor right. i got lots info from these guys. very helpful and friendly. just tell them what your planning and they will figure the rest out for you.
 
im interested in the original topic which nobody in 3 pages has even answered. i got a 1990 burban but i am going from the tbi 350/700r4 to a built 454 (carbed). its 2wd though so i dont need the efi. i know its not 4x4ing but its gonna wax hondas and stangs! just wondering how to keep everything like speedo etc. that was controlled by the computer operational. i believe there was a thread on here some time ago talking about a theoretical burban that was gutted and built up for this kind of purpose
 
If you swap in an older tranny (TH400?) with the new engine, most of the rest will be straightforward.
 
Yeah with a built 454 your gona want a th400 , i would go with a reverse manual valve body setup with ratchet shifter on the floor. Your gona need to strip alot to get your hp to weight ratio correct to dust imports. personally id love to see it. good luck
 
91 is a traditional 700R4/4L60. 93 was the first year of the 4L60E. I had a '92 Blazer K1500 and it had the same trans that a '91 would have had.
 
my curb weight is 4528. my 454-533hp and 570 lbft at the flywheel.dynoed.

Calculate 1/4-Mile E.T. From Horsepower
Vehicle Weight: 4528
Wheel Horsepower: 455
Flywheel Horsepower: 533
1/4-Mile Elapsed Time (E.T.) = 12.52

This calculator esitmates your quarter-mile elapsed time (E.T.) when given the weight of the vehicle and flywheel or "at the wheels" horsepower. A 17% driveline loss is assumed for flywheel HP.

now lets say 4528 lbs isnt accurate

i had a 72 town&country wagon with a 440,stock 6pak cam, ported iron heads,torker intake,750 speed demon carb,1 3/4" primary tube headers, 2.5" exhaust with 2 chambers flowmasters,stock converter, 2.76 open diff and 295/50 radials that waxed my buddies 02 mustang regularly when it ran 14.1's at the track. im not concerned about the weight of my burban.

as for the 700r4, i will make sure all the necassary parts are used to make it survive. i want the steep first gear and the overdrive. im not worried about the cost, thats what i want and it is what it is.
 
In real world your burban with street tires and 454 will run if your lucky in the 17's or so. if you can get those turds to do faster id love to see it. now if it were gutted and built right (suspension & such) in a 2wd version with the motor and a good solid th400 trans launchin at bout 4500 rpm maybe a 13-14 et. Youd never get into the 12-13's with a 4x4 burban under natural asperation. Plus if your 454 is putting 533 to the ground that 700r4 would bust on your first launch! also i wouldnt brag bout 14.1's to much either. just my $0.02
 
Seems to me the biggest difference in whether injection is good for your situation or not is directly related to how much knowledge you have about Fuel injection vs. carbeuration.

Some of us grew up with carbs and know how to work with them. I would imagine if we (carb guys) new more about FI and how to work with it we'd probably appreciate it better. In the end you need to be able to work with it on the trail, or in the middle of nowhere on hwy Lost 15, alone and far from support.

If you can gain the knowledge that FI requires, can carry some extra parts, you'd probably be better off.

first off, i said the suburban my 454 is going into is 2wd and i have 30x12.5 et streets for it. secondly i have personally seen a 3/4 ton 2wd suburban do 12.30s on street tires at a drag strip and its the exact same truck i got my 4 core rad and roller rockers from. a low 14 second et is very impressive for a tank station wagon, maybe you should read the specs on it again. it was pretty much identical in size and weight (actually heavier) than my 2wd burban. there are parts available to make a 700r4 withstand that kind of power and i have no problems spending the coin on doing it.

check this out http://www.youtube.com/watch?v=4Y2vUqEsWMM

instead of all you guys telling me it cant be done, try helping me out and come up with ideas on how to make it happen, and with a 700r4. sometimes when a group of people get together and think about something, it sparks new ideas that someone else may have overlooked. i thought thats why these forums were for.

I agree if someone comes on here and wants to make his truck do what ever who cares let him or her. However this is a 4x4 web site so not to many people are going to have the knowledge.

I think its a cool idea stick with the 700r4 if you want, I would go to the 4l80E and spend the coin there. Its stronger from the get go and still has the overdrive. I would also do and aftermarket FI that you can tune with a computer cuz I think that is the best tunablity you can get. Most kits are easy to set up and run. If you have the carb and do lots of changes then its new jets and stuff with the FI its change the program and you done.
 
1st off You hijacked another guys thread in a 4x4 and offroad forum (at least start your own thread)
2nd I would suggest you buy a membership
3rd that trans you are looking at will not hold up!
all you have to do is read the web page you posted up and you will see that it is not recommended for the torque you have specified. Hp & torque are to totally different beasts. Torque is what breaks stuff. I would put money on it that that burban running 11's has move than a beefed up big block. Im sure theres a shot or two of nitrous in there. Plus im sure if you checked with him he's using a Built Superglide trans or a Built th400. He's probly coming off the line at 3500-4000 stall. There are plenty of people on this board that have plenty of knowledge to pass on but post your own thread.
 
i understand this is a 4x4 site as i have an 89 4x4 suburban. its lifted, its got some engine mods, the trottle body has been modded, i am slowly piecing to gether and rebuilding my front 60. thats why i follow this site. the tread is about losing the computer. i originally asked about what to do about things like the electronic speedo. someone said put a 400 in. i dont want a 400. who really cares if its not 4wd? its the same topic, its still a gm, its still automotive. how many of you own 2wd trucks as well that have posted a question regarding it? i have seen many.hijacked or not my original question was relative. i realize most would just put in a th400 but thats not what i stated i wanted to do so instead of helping me with my original request, you all bust my balls about how things cant be done when in fact they can. i posted the link to the 11 second suburban because too many of you thought that what i want to do isnt possible, yet im sure seeing that burb haul ass put a smile on your face. if you were to actually carefully read, the bowtie overdrives link shows a Extreme Duty Street / strip tranny with a hp/tq rating of 630 maximum which is definately suitable. my post may have been a little off topic but all i was trying to do was give you guys some insight on what i was doing to aid in your reply but instead i get narrow minded responses. a 4l80 e would be great,i love the idea but i figured its expensive to obtain, then i need an expensive controller and in the end, its still a stock tranny. i just never understand when somebody posts a neat or different idea thats out of the box how everyone is quick to decline it or tear it apart. do you guys honestly enjoy reading all of the silly post about "which all terrains someone should buy" or "look what i saw on ebay"? im just trying to be different with my street rod which im sure many of you own as well. if i have stirred the pot, my apologies to all as thats not my intent.
 
Behind engines above 450 hp and 450 ft/lbs. of torque output, the input shaft to drum connection point becomes prone to fracture and the spline sun gear section will start ripping off the sun shell.
Our Level Two Transmissions parts have proven very reliable up to torque levels around 400-450 ft/lbs and our return rate demonstrates this.
That is what ive found on the site you posted.

I found this on another site.
[FONT=Arial,Helvetica,Univers,Zurich BT,sans-]#PT700R4SX [/FONT]
This is our strongest version of the 700R4 and is rated at 575 horsepower and 600 lbs. of torque in vehicles up to 3700 lbs. We take all the modifications and upgrades from our PT700R4SS and add Billet second and fourth gear Servo assemblies , heavy duty reaction sun shell, 5 pinion rear planet and a host of other durability and performance modifications to create the strongest 700R4 available. Comes with our ‘TORQUE-MAX’ torque converter in stall speeds up to 2750 rpm. If you are looking for the strongest, toughest performance 700R4, look no further; this is the trans for you! $2289.00

Not sure but you will have to lose a lot of weight on that burban to drop to those numbers. not sayin it can't be done though.

And here is the info on the stand alone controller setup

Are you a Muslim Extremist? Will you please stop hijacking my thread.

....meant to be funny, not mean....
 
I haven't contacted tbichips yet.

I've got the dreams of what I want to do. I'm preparing to get it done, most all of it at one time so the truck isn't down for too long.

I run my own business, so I'm trying to see what my year is going to finish like, how much I can bonus my employees, how much taxes I'll pay, and how much I can take without sacrificing the future. Usually, it's less than I would like to think.

There was another thread on here, something like; "Four years and I can say it's finally done". That guys doing pretty much what I would like to do except I don't think I need the 60. It's more of a fancy hunt truck, grocery getter with a lot of HP! And all of this adds up to more time and money than I want to part with.

Damn those priorities!
 
It sounds like you are kind of undecided between TBI and Carb. As said before 4 pages of talk. No one really answered your questions. SO...................
If you want to swap in a Carb 383 you will need:
Intake Manifold and Holley Avenger carb with TV linkage kit $600
HEI or points Dist. $100 and up
If you use the stock in tank pump need new regulator with return. 100
Mechanical pump will be cheaper.

So you are looking at plus or minus $800 to do the TBI to Carb swap right with new parts. The benifits as you already Know are simplicity and you know how to work on it. The engine will make more power than TBI once you get the Holley tuned. But. You will definatly give up fuel mileage 2-4 MPG depending on tune. if you want to use your TBI heads you wont see as much power gains as you would with a set of Vortec heads. If you use Vortecs add another 600 to the price for new heads. heres a link to a turn key 383 with almost everythng you need for reference:http://paceperformance.com/index.asp?PageAction=VIEWPROD&ProdID=197333

For a 383 TBI if built using your TBI 350 and heads. Heads should be mildly ported and performance valve job with a mild cam. Besides the needed engine work. The minimum you will need to get it up and running good is:
New chip $250.
That is about it.
You can get more power with bigger throttle body and injectors, cam, heads ECT. But you said you want to keep it simple.
Heres a link to a nice 383. They also have the chip that will work with it so it is basicly plug and play.
http://www.blueprintengines.com/popular_configurations/index.html?topic=specs&pc_id=32
With this engine, stock TB and their chip you will have the power of a big block with close the gas mileage of a TBI 350.If you can keep your foot out of it.

As said TBI is not that hard to work on. It is a very simple dependable FI system. If you decide to go with TBI I highly recomend you get a scanner. You can get a GM OBD1 scanner fairly cheap on Ebay.
Personally I would never go back to a Carb. Everything I own is FI and Love it. It does not take long to learn how to work on it. Once you get a basic understanding it is fairly simple. Besides there are many of us here willing to help you out.

Hope this helps.
 
Talk to the guys at tbichips.com the chip wont cost you much at all. tell them what your planning heads, stroker kit cam, exhaust etc. they will tell you what will work if you need new heads what cams work, and give you some suggestions on parts. best free tech i ever got was from those guys when i did my 406tbi motor
