Re: Need some help on a motor build
Lift limit in stock form is between .450-.480 lift. The castings aren't perfect and some heads will have more clearance than others. Generally Vortecs don't flow much past .480 lift anyhow so going with a big cam is pointless. The biggest I would bother going with vortecs is something along the lines of the comp xe268. If your focused on low to midrange the xe262 would be a good choice.
