I had a guy pickup a stock built 700r4.
He told me he's putting it behind a 475 HP 383 stroker with a 200 shot of nitrous.
He's got a 3500 stall convertor. I was told its a non lockup?

Any comments on this and how long before this thing grenades? :drunk:

it depends on how he drives i guess. if hes not very rough on it, and maintains it, could last for awhile provided:
it has had installed a converter valve kit (non lockup pump conversion kit)
has no intentions of racing it

other than that, this thing is gonna fail in short time i believe. but of course, ive been wrong before, just everyone else on the planet. :mwink:

 

Fathers Day Present?

For Fathers' Day someone should get him a shop broom,big metal dust pan and a large sack of kitty litter,it'll come in handy!

 

A decent rebuilt B/M 700R4 is good to 450 ftlbs torque.
Buy the tranny a diaper.

 

Hope he bought the unlimited service contract

I told him I'd take it apart for nothing just to see how bad it is inside. :mwink:

Hey tnsmith.
What is this convertor valve kit you mention?

 

TransGo # 7-CCV
http://www.transgo.com/valve_bushing.php
http://www.makcotransmissionparts.com/T74165A.html

 

the valve corrects fluid path into the converter when a non lock up torque converter is used.

 

I've got a stock 700r4 behind my 406, it dynoed 531hp and 529tq at the flywheel. I launched the car off a mild stall with a bad carb tune and cracked the bellhousing in half...

 

Hey tnsmith.
What is this convertor valve kit you mention?

the kit i use is from transtar. part # T74165A.
crosley mentioned what it does. i have 1 in each of my venturas, 1 my dad and i built in 1996, and has over 150,000 miles on it, and still going strong. the other i just had to pull it back out and have had to go back into it cause the "basket"in the input drum got stuck on the load plate for the 3-4 clutches. its already been fixed and back in the car.
both cars came with chevy engines so thats why the 700 was used and not a 2004r.

 

tnsmith10, How much is the Transtar valve? I've heard some are much cheaper than the TransGo.

 

when i get back to the shop on monday ill find out. i dont really know off hand.

 

So where does the convertor valve kit install?
Is it for use in the oil pump?
I may have to get a hold of this guy to install it for him.

Kit installs in the lock up valve bore of the pump... take pan off , remove snap ring to remove parts , then install kit.

 

Thanks Crosley.
Sounds like an easy install.

around 35 bucks through W.I.T. Trans online. same part # as transtar.

 

Blaaaammmmmm!

Didn't last long.
I had the kit for him and he never came to get it.
Probably thought he didn't need it.
Says the 3-4 pack is smoked already.
