Why I haven't commented earlier in this thread is because the converter police always shows up and demands that everyone buy a $1000 converter for whatever they are working on or whatever they are trying to do. On a budget its perfectly fine to use an off the shelf converter, they do stall higher than a stocker and will be more fun to launch the car with(its a hobby car after all, not so much a daily driver IIRC). On the down side it may make the engine run more RPM than what it should run when just cruising around. If the person buying the converter isn't worried about the extra RPM when cruising around then no big deal.(just make sure to install a trans cooler because the higher stall will run hotter, don't want to burn up the trans because of the converter) With the one he is looking at only being a 2000 to 2400 RPM range I don't think the extra cruise RPM would be that much more. IIRC the Grand National converters stall around 1,800 from the factory so a couple hundred more RPM than a factory built unit. If it RPMs to much, change the cam to something bigger. I have an off the shelf TCI 3000 stall behind a 700R4 that is WAY loose, not a big deal to me because it is a lockup converter so when I'm cruising the freeway I lock the converter and its direct drive. I realize the th350 converters aren't offered in a performance lockup style but with conservative 3.08 gears that little bit of extra RPM wouldn't be all that bad on the freeway anyway. You should have some more driving fun with the one Ken recommended, the TCI converters aren't all that bad for an off the shelf converter to have a little more driving fun with. When you're ready to step up to a better one, keep the one Larry recommended in mind.
