Torque Converter

Ok I'm putting a 700R4 Transmission in my 72 SWB. Its a 350 Crate Motor with a small cam and has a limited slip rearend, with I think a 4.10 gear.....I was wondering if you guys could give me a round about for what stall converter I would need. Can anyone help??

thanks

Re: Torque Converter

since you went into such great detail about the cam, you wont need any, stock is fine.

Re: Torque Converter

Well if I could see it, then I could tell you more about it! I just got the truck. All I know about the motor is that its a 350 Crate motor. When it sets at Idle, you can here it lobe pretty good.

Re: Torque Converter

I have a mild 350 with a 700r4 and a 3:42 rear in my 64... The stock converter is perfect for my driving habits with this truck..

that still means absolutely nothing, what i think lopes heavy others think is mild and what i think is mild others think is radical.

unless its is some wicked spanky crate motor a stock will be more than enough.

since its a crate why not look up the specs from gm?

Re: Torque Converter

Strut,
what's the idle rpm in gear with the current set up? Also try and hook up a vacuum gauge and get some reading in idle and park. Don't pay too much attention to harsh coments.

Sounds like you have the same problems I'm having.
It was recommended to me to get a 2400 stall...

Re: Torque Converter

If you have a shop in your town that rebuilds torque converters they should be able to loosen up your existing converter to @2000rpm for about half the price of buying a new one and still have the lock up feature. That's what I did to the one in my 700R4.

Re: Torque Converter

I have the exact same set up, well, I'm not sure what you really mean by mild cam, but I have a 3000 stall with lock up and love it. But if your cam isn't to radical you could run a 2500 or so.
