I am gonna put a cam into my 92 4.0L, i have found some that comp cams sell but for 300 bucks, does anybody know where else i can get a cam or aftermaket parts for my motor for resonable price as i dont feel a cam is worth that but will prob end up payin anyways! A nd i was also wonderin bout if i can just put in a lumper cam or do i need other changes to get more power! The truck is stock right now with 300k on it
