it sounds like you dont want tomo make a ton more hp and tq than stock, I would take a look at your block it might be machiened for the stock vortec rooler assy. if it is then you can runa stock vortec cam. vortec specs are 250 hp and 350 tq so that would be the best option if the block is prepped for it. if not a lunati 4x4 cam would make great driveable power. the second smallest one. i will look up the specs.
