I looked your cam on the summit website and Howards suggests a 3500 stall for that camshaft.The stated powerband is 2800 to 6400 rpm.
Which torque converter?

Not stealing this thread. The comparables relate. Maybe the OPs 2800 is the better choice for street. I think more stall than that is too much for daily driving.
Like to hear how the 2800 performs....

Sure thing, I will definitely report back. I'm going to try the existing motor and torque converter together to see what it feels like, which works out well for both my education and also my budget. It will take a few weeks to get the rest of the parts in and do the swap.

Small blocks and long duration camshafts often need a higher stall speed so they can idle in gear. I'm running a stock torque converter behind my 454" with a 236/236 duration camshaft but it'll idle at 550 rpm in DRIVE okay because of the amount of torque at idle..

I guess I'll see how it drives. Skip White and Mad Dog Trans recommended 2200. So I went with that.

@AggitatedMonkey, nah, i haven't run it yet. I'm ordering the rest of the parts tonight to do the drivetrain swap. What I've learned since posting is that the tc is a 12", is made by Transmission Specialties, and the original rating is 2400-2800. I'm felling more optimistic about a possible good match. I should be able to report back in 3-4 weeks.

Any progress on the stall converter? I did end up changing mine. My cam calls for 3500 stall as mentioned earlier. I'm hard headed so I went with 2800 stall. Drives very nice and idles nice with my big cam. Drops in gear like stock. However with my foot in it its a monster. Just wonder how your car was running with the stall you have. Update us.

If you are really wanting a different stall speed I would limit it to 2000 rpm or it'll feel real "loose" in all the gears until the revs exceed 2000 rpm. Many people make the big mistake of buying a stall speed that is way too high and then their overall performance suffers. High stall converters are needed for "off the line" drag racing but if you seldom give it a full throttle from a standing start you're much better off using a stock stall speed.

No, I dont have the engine back in yet; I got delayed by upgrades: radiator, headlight vacuum overhaul, a/c refresh, hvac vacuum refresh, wire harness replacement, engine compartment paint & cleanup, heat shield, blah blah blah. (I now understand why some forum choose not to keep track of costs...) I can't wait to report back, but nothing yet.

I've cut some of my stock and cheaper TC's in 1/2 to see what failed just behind a hot rodded 355 ci. The first time i power braked my 12 inch equipped TCI 700r the stator spline shattered. I just said screw this cheap junk and bought the best. I never had a problem as my motors continued to get bigger and my slicks got bigger

It is all I can do to not say something rude
TORQUE converters MULTIPLY torque ,, until they reach stall speed where at that point it transfers power on about a 1 to 1 basis with your crank shafts rotation. ( About 1 to 1 because there is some inefficiency in the system) Later technology introduced lock up which mechanically locked the unit to the rpm output of the crankshaft
Down low at idle and light throttle or a steady drive the converter behaves like any converter in any car , you can not feel it , the car does not "slip while in gear " or do anything you would consider bad street mannered.
Evert time you see tach drop to about 1500 i am in O/D ( 4L80e ) ANy time you see tach drop to 1000 or so i am letting off throttle .

I had refrained from any comment to toobroke as I could not beleive what was stated. This information is the correct answer. Thanks for the viedo. GKULL has provided great information also.

I have a 406 CI with a 700R4 475HP
3:90 gears
idles at 900 RPM
I am new to fast cars and corvettes but I like the way it drives.
Drives completely normal like any other car under part throttle driving..., and when you floor it, I like it too.
Revs at 2200 if i remember in OD
and in lock up 2000RPM

He probably "built" his own high stall converter. 
He would never pay the money for a quality converter like a PTC and I doubt he has any car "buddies" with one so like many other topics, he has no clue what he's talking about here either.
Since the OP has that 2800rpm stall converter, he might as well try it first. But, he may find it's not great unless it's a higher quality unit.
