Re: To cam or not to cam?
2)Thatīs easy[img]images/icons/smile.gif[/img]. The one and only cam for a 4x4 pickup is a mild one from the Competition Cams Xtreme 4x4 series or Xtreme Energy series. Do NOT let your friend talk you into any other cam [img]images/icons/crazy.gif[/img].
3) Thereīs a difference alright. Youīll gain maybe 40 ft.lbs of torque & 30 horsies while getting better mpgīs. So eventually itīll pay itself off. With a new cam you always buy new lifters. Ususally you can buy cam and lifters as a kit, and save a few $. If you wanna go by the book you also get new valvesprings, timingchain and *gulp* new cambearings. If you have to change cambearings then itīll get tricky. Special tools and knowing what to do is an absolute must here. The cambearings go in a special order and can not be mixed up.
4) Well, yes. When you change a cam you have to remove the intake, and thatīs what youīre doing right now so.....
Summit has a cam-kit with Comp Xtreme 4x4 camshaft, lifters, valvesprings, retainers, locks, valvestem seals, timingchain and assembly lube (and decals[img]images/icons/smile.gif[/img]) for $270. Partnumber is CCA-K12-231-2. Check it out. Or you could just get a cam and new lifters for $170 and forget about the rest. Your stock valvesprings will handle the extra lift but they might not handle it well when the rpms are up. You can be REAL picky but the question is; is it worth it, considering the rest of the engine/truck? I bought matching valvesprings for my engine but thatīs with a higher lift cam and the d*mn thing is $4000+. I donīt wanna take any chances [img]images/icons/smile.gif[/img]. My truck doesnīt deserve the 406, haha.
