more converter stall speed???

GRUMPY, Please let me start with Thank you for the 383 build info it is awesome.
I'm trading a friend my 454 for a 383 he bought off an old rodder guy at his church: which was about 15 years ago.
He is not sure what all has been done to the motor due to having purchased it so long ago, plus we can find the old rodder.
What I do know it is a 383, I removed the oil pan and measured the stroke Wisconsin came out to 3.75.
I'm not sure of what cam is in it and he doesn't remember due to the length of time.
It has Erson roller rockers on it and stronger double springs, the rockers are 1.60. What is the advantage or disadvantage of 1.6 vs 1.5?
I'm also thinking of putting in a cam that I know what is in it with the specs of:
Operating range 2000 to 5.600 rpm
Intake 224 Exhaust 224
Lift 466
Lobe 114
Summit calls for a 2000 to 4000 stall
This is where I'm getting conflicting information. Do I need a stall or can the factory setting one work? As far as a stall goes will the car move with out reving to 2000 rpm or do I need to Rev up to 2000 just to get it to move?
Sorry for emailing you it just seemed to be a better place to ask this rather than in the forum.
Thank you for you time and excellent information and wisdom.
Thank you

a torque converter stall speed thats rated at lets say 2000 rpm, does NOT in any way indicate the engine needs to reach the stall speed before the car will move, thats a total myth , my corvette has a 3200 rpm rated stall speed the car pulls well enough from less than 1900 rpm,at part throttle.
basically the rated stall is a predicted rpm level but every engines torque level will be different and thus the actual stall will vary.

Runout - runout should be less than 0,25 mm (0,010 inch).

Balance - should be checked with the turbine in at least three positions. This insures that the converter will
not be internally out of balance. Overall balance should be held within 10 grams.

Internal Dimensional Standards:


Fit of pilot bushing
- 0,10 mm-0,20 mm (0,004 inch - 0,008 inch) typical.
