packrat, i absolutly love the 292! when i originally purchased the truck i planned on installing a mild 350. after the first time i heard that 292 purr and drove her around i changed my mind in less than 2 sec. i am hooked on these inline sixes. as far as the trans goes.. for now i am gonna stick with the 4 speed hook'd to it as i know its plenty tough enough for the heavy loads. still interested in what everyone else has to day on this topic.
