Can I drop the trans and the Tcase at the same time? Like leave the Tcase still attached to the trans.
yes
yes but double the weight if u re not using anything ...
yea depends alot on what it is in and it does help with weight ALOT they are heavy as hell
It's a 700r4 with a 208 Tcase. I was gunna drain all the fluid so I'm not holding an extra 14qts. But it will be me and a friend removing. Don't have a tranny jack:( and it's cold outside
i would just split em its like 6 bolts holding them together

Well I know there's a support bar that goes from the Tcase to the bell housing. It's cold outside, I don't want to be messing around too long. Lol.
still will be a bictch for 2 person cuz u wont be able get in good position to hold it up , but good luck and be safe , use jack or maybe straps to hold em up while u re unbolting em

Straps are a good idea! Thanks. I don't have a jack, but the truck is tall enough that I can kneel comfortably, so I could prolly hold the top or bottom of the trans on my shoulder while my friend holds up the other end.
I always drop the tcase b4 I drop the trans. It only takes like 15 xtra min with a 208
How much tranny fluid does that tcase hold?
it doesnt hold that many quarts maybe 4 or 5
Should I leave the T converter on the flywheel? Or on the trans shaft?
First trans removal, can't ya tell? ==noob

thats easy to do to just pull it.
i would leave it in the trans
Ok thanks alot fellas.
Can my trans be built up to handle around 850hp?
unbolt the convertor from the flywheel, take the transfercase off the trans. there is no shortcuts to this job. if your outside have a can for every nut and bolt, and take the distributor cap off so you dont break it.

Idk how I'd break the distributer cap?

If you dont support the back of the motor, when you pull the trans back the motor will drop and your dist will hit the firewall. Crack goes your cap.
Ohhh. Thanks, GREAT tip.
But could I get this rebuilt into a proformance trans? And at about how much $$ ?
yes you can but it will cost big bucks and if you really plan on running that kind of power i would look at a different trans

Yea, I already got the power. But I REALLY like the 700 cuz of 4th gear. I drive this truck daily in the summer time, and after work and on weekends I bog/race the living p00 out of it. So I do use the power I make.
And I like 4th gear for roads, I'm not spinning high rpms and save a lot on gas.

x2 if you really have 850 hp I would look for a 400th to have built to run the power also with that kinda power your gunna want a converter built to run your motor , gear, tire size, and truck weight so everything works right.

Yes I've been doing my hw on what I can. It's not 850hp, it's 800 (depending on psi) I just want to be safe. But I need a 10" 3500-3800 stall, and one that's for nitrous/blower applications. I do have a tranny cooler, but idk how much that will help. And I know a th400 would be the best for what I got, and it's alot cheaper. But I don't like high rpms on the road. But I guess that means drive slower or get bigger tires ;)
Will I run into any trouble swapping the 700 for the 400? Like any mounting differences? Or length changes I have to worry about?

shouldnt maybe have to mess with shifter linkage for tcase?? but make sure u get the acutal mount for trans

the mount that goes across from frame rail-rail that holds up the back of your trans/transfer case. or if u want u could build your own
What are you running that has 800hp on the street. If you really have that much power I don't see overdrive helping that much since it drinks the gas anyways. I would go for Turbo 350 or 400 over a 700r4 anyday with that much power. You could always go 4l80e if you really want overdrive but that's alot of money.

4l80e wouldnt be the best lol that would be alot of money you would have to get a stand alone computer
For overdrive built transmissions they can't be beat. Alot of money but the newer 1000hp vettes are swapping from the pro built 4l60es to the 80s because they can handle anything you throw at them.

yea but you will probably have more into having it built then its worth 800 hp seems a little much for the road imo

Well, have this old built muscle 427 sitting in the polbarn. As is it's about 6-700hp. Got a blower now, putting a few pounds. Got bored this winter, looked at the truck, looked at the motor, looked back at the truck, then smiled. I think some of you guys may have had that feeling befor.
But as far as the trans, I blew my $$ fast on the motor. Lol
So budget wise, I'm leaning towards the 400, but since I'm out of $ and short on time.I figured I would just bite the bullet and was just going to try and keep the 700 and just save up and build it since I already have it. Cuz I'm worried I won't find a th400 in time.

When the trucks finished I'm selling it and putting the motor back into a car.
What the compression on the motor without the blower
I have about 950 bux into my 700r4, and 250bux of that was labor.
But I'm only rockin about 400hp
Quote from: ice87 on February 17, 2012, 11:38:38 PM

12:1
6.7" pink rods
I have another set of flat top pistons for it, that would probably be better for the street and lower compression. But like I said, I'm on a time frame, so I'll just run like 3-5lbs boost. I could even underdeive the blower and run lower pounds to make me happy with MPGs.
In the boat I have a stock 454 with mild hydraulic roller cam running 9lbs on a 6-71. And it's pretty good on gas cruising alll day long. But if you hot rod it, then yea, it sucks the fuel.

That's what I was thinking. But that's how the motor came stock from GM (I think)
But like I said, I have another set of lower comp pistons. When we got the motor it was pretty well built from GM. Then we modified it with a little more cam, longer roller rockets, stud girdle, rods and crank.
The motor was featured in the 1976 2nd addition Chevrolet Power manual.
you could run a blower but wouldnt go over 3 psi that would bring your compression ratio up to 14:1 but then you need to run racing fuel like 110-114 octane. you dont wanna go over 12:1 on high octane pump gas.
I would advise against it but to each there own lol, Im runnin around 9-10 psi on my motor and have a 14:1 ratio but it adds up in gas fast lol

Yea I was planning on keeping it 3-5Lbs. And I could change the pistons on a rainy day. But the heads are from another motor. The heads are ported, flowed, and cnc'd. Harder valve seats. Roller lifters, springs matched to the valve train.
And I know what you mean when running 10lbs WFO = empty tanks
But I chose a blower so I have that instant off the line power and boost. And hell, to me it looks cooler than p00 with the scoop and belts through the hood.

save up run the 700r4 for now and when u can buy a 400th buy it and build it to hold up to your motor problem solved
I'm just gunna get rid of the 700r4. Get a th400. And build the 400 up. Anyone wanna trade? Sell? Buy?
if you were closer I would probably buy that there r4 from ya :)
