Wow $1900 ! it would want to be 24ct gold plated, in my petrol head days messin about with the indestructable tweaked 2 speed powerglide boxes with modified 1,500 / 1,800 rpm stall converters cost less than $300 for a tricked up one.
For ref sake the beast used to do just on 115 in 1st, that's MPH too, from memory it was a 1,750 converter, that gives you some free play to allow the odd throttle blip to keep em alive for very ugly lumpy cams that idle ? / run slowly at around 1,250 and that allows your torque to be up before the converter is fully engaged, a bit like dumping the clutch, anyone that has run 45/95 cams with huge overlap knows what I mean, add tripple 2" SU's and the fun starts.
Even with the age difference a stock converter is nothing more than just a fluid drive coupling, washing machines have a basic torque converter, Simpson "fluid drive".
Installing one is about as simple as it gets, the converter is bolted to the drive plate with probably 4 -5 bolts, the tranny side has a simple square cut out of the input that mates with a lug inside the front of the tranny, some have splines, either way it's not hard, it's usually a matter of turning one or the other until it engages in the tranny, do up the bolts on the drive plate and your in buisness.
