one more question

i have a brand new torque converter laying around. it is for a forged steel crank and wondered if i could use that for my 383. it has a forged steel crank also. it isnt a stall or anything just a regular converter

You may have to drop the valve body to change the selector shaft seal but that's no big deal. Just be very clean and pay attention!! The dip stick tube has an O-ring and it's not always a perfect seal because the tube gets bent up around where the O -ring seat is. You may want to back it up with some Right Stuff (I call it black death).

No weights on the converter, correct? Also make sure it's not for an early trans going into a late trans. The early trans has an 18 spline input vs. the 19 spline on the newer stuff. Otherwise should be fine based on what you said.
