If I stick with the Vortec heads what size cam would y'all recommend. And I would like to know a few options on sticking with the TBI or switching it to a carb and get rid of all the computer crap. If I switch to the carb and it don't have a computer does it matter what size crank and cam I put in it. Thanks for all the helpp. When I start building it I'll try and add some pics to show everything thanks again
