    Max lift for the 4.8 with 706 heads???

    215/231 with a .631/.644 lift @ 118lsa. If I have the .650 dual valve springs, retainers, and pushrods will this cam work, or will I have to get a better intake to see the power. LSA should be a good street cam or turbo cam right?

    MOTHER OF GOD! Dude, Jeff--that cam is WAAAAAAAAAAAAAAAAAY too big for a 4.8L--IMHO. Even if you had a 3600 stall, every bolt-on imagineable, and built tranny--there is no way your truck would be able to be driven in the street decently. With the LSA, it sounds like that cam was ground for a FI 408 motor...
