    Without knowing what you have in your engine or the actual hp output of it, the weight of your car with driver in it, the rear end gear ratio and tire size we can only guess at what you need for a higher stall converter.
    On top of that when you order your converter if the information is not accurate the stall will be higher or lower than you order. A 2800 rpm stall converter for a 300 hp engine will stall considerably higher behind a 350 hp engine and if you get one for 2800stall for a 350 hp engine but only have 300 it will stall considerably lower.

    Can you suggest a stall for me? 302 .30 over, 292 Comp cam, Performer intake, 650 DP, 4.62 gears, C4, 14" tires... anything else?

    1970 was when the c4 changed from a 24 to a 26 spline input shaft. :)

    After all the crap Eagle Transmission has done to me, I shoulda wrote that, and all the other, information down.

    All right well the motor has a high high cam with dome pistons and open chamber heads. I cant remember what size stall the guy said but what do you thinks think? And is there anything inpedicular i should remember when buying a stall for an 83-84 AOD Transmission.

    If I make the assumption that this is for a Maverick or Comet and that you weigh around 200 pounds and if my memory serves me that cam gets peak torque around 3800 rpm I would recommend about 2500 to 2800 stall for your application. That will give your tires a chance to stick before you start transferring full torque to the rear wheels. If you were using bigger tires you could increase the stall to 3500.

    357,
    I need to know at least the compression ratio, what heads and cam specs, weight of car with driver, and rear gears.
    You said earlier you were using 3.55 I think, so what tires will you be using?

    Here are the only things i know. 10:1 "open chamber heads and racing cam"
    3.50 gears 2 different drivers 100-200 pounds 15 inch tires. I dont know specs on cams or heads. I bought this engine from a mechanic and now i do not have his number.

    With this car not seeing the strip, why go any higher than say 2000-2200?
    That will give a little bit of extra pull from a dead stop, but if he's not racing, then why give up streetability, and so on for "a couple of tenths off the 60 foot times".:huh:

    If the cam is radical a 2000 - 2200 rpm stall converter will not be enough to let the car idle without issues. It would be a nightmare to drive with stalling and slow take off. THAT is why you need to know what is in the engine before selecting a converter.
