If your set on HEI then I would get a Factory GM unit and have it rebuilt and curved by a competent rebuilder. The factory units are good just not as shiney and none of the aftermarket ones will come curved for you truck. So new or used you would still want to have the unit's advance curve dialed in for your combination. I've bought dozens of used HEI's for between 5 and 40 bucks.
