off the cuff, something like a factory 340 converter would be fine so what 22~2500 (that would be for a low end converter). i mean considering a stock 318 converter is like, negative stall (i'm kidding it's probably 1800) i'd think anything 2+ would be an improvement.
now if you're talking high end, 2800~3 would be a nice choice. but then you're looking at dropping 6~7 hundy
What would a good quality 2500 - 2800 rpm converter cost? I don't need the very best buy I don't want junk either, I don't want to have to replace the converter in like a year because it was cheaper
