Factory High Stall Converters
The problem with a very hi-stall converter in a street machine is the trans feels mushy when it shifts just driving it to the grocery store because rpm drops to below stall; post shift. Your car will feel boring and it gets old quick. Converter choices are all over the place, but the companies that make individual recommendations usually charge an arm and a leg for a "custom" converter; when they can usually be purchased for about 1/3 the price...even from THEM. I say err on the side of caution and go with a lower stall than all your friends might recommend. They don't have to drive your car every day. Some of the factory hi-stalls can be bought at your local auto parts place for under $100.
