hello all, and thanks for the help before hand. i have been tryin to help my buddy with his engine prob. but he won't listen to me!(a ford thing i guess)! he just put a rebuilt eng. in his truck and he says it won't rev past 4000 (i can hear the ford jokes now)! he put a new dist. in and still has the prob. he says it runs good up to there. i have told him what i think but i thought i would ask u guys. any help? thanks
