Yup...early 700's were the small shaft, 27 spline. The stall speed was depending on the engine used...V-8 or V-6. Gasoline V-8s were normally in the 1200rpm range, diesels were much lower, smaller V-6s were higher.
The stall speed is the rpm reached at the time the car starts moving. If you put your foot on the brake
hard, with the trans in gear, and mash the go pedal all the way down, the stall speed of the converter is whatever rpm you achieve before the tires break loose. Please, if anyone tries this, do it
Safely...not in the garage, or with other vehicles/homes/people in front of you! This only takes a second or two...you don't have to hold the pedal down long.
(btw...this ain't the scientifical way to do this...it's just a simple explanation of how you can get a good guess of your stall speed)
The stall speed is more closely related to engine torque than anything else. An engine that makes a lot of low-end torque doesn't need a high-stall converter. The idea is to get the converter stall speed at the same rpm the engine starts making it's torque numbers.
A stock '82 could prolly go to an 1800rpm stall with no other drive-ability issues. Since the cross-fire engine is really limited on the rpm range, I wouldn't recommend going to a high stall converter. If you stay close to stock, say 14-1800, it should be fine, but you will notice a little more rpm before the car moves...it may feel like it's slipping a little on take-off, compared to what you're used to with the car.
