How did you pick your torque converter?

Do it right the first time. I called PTC for a quote on mine, they need to know as much info as you can provide. Car weight, intended usage, engine specs cam etc., rear gears, trans, tire size. Mine came in at around 700.

It might seem pricey, but do you want to got to all the work and expense to put one in that you aren't happy with? And then have to do it again?
