okay i have been planing on doing a 6.0 swap into a S-10, and want a cam that will pull though out the whole RPM band, i am thanking a 224/224 on 114, and would i need a tune or stall with that cam? i just want to stick wiht stock heads for now, so what kinda #'s could i Expect with that cam on stock heads and a good free flowing exuast and maybe a tune?
