anybody have any advice on choosing a torque converter for my application. i have a 72 blazer 4wd cst that i'm about to put a crate 383 engine in with 425 hp, and 450 torque. currently still running with th350 transmission. trying to get a 4 speed auto trans some day, but i need something for the time being, maybe something that can be used on both? help out if you can or point me in the correnct direction. thanks!
