I have an 04 2500hd 6.0l. I have to replace my knock sensors and my water pump is leaking. Started thinking since I have to replace water pump how bout a new cam. I have done one on my old 97 5.7. How much more work are we talking to replace cam. Truck is all stock and do not want to lose bottom end, it is used for towing. thanks
A lot of the new guys are stuck on the bottom end thing. Truth is, most cams dont make you ''loose'' bottom end. They just appear to because the top end has much more contrast of the low end. If all you going to do is a cam, and no other boltons period. ''hardly no one does this cause its addictive'' In my opinion I would get a cam in the 218-225/218-225 .525-.580/.525-.580 range. Keep lsa between 112-116. You should be fine.Originally Posted by coreyhd
If you want the most power with a better than stock low end, there is a cam called the ''cheaTR'' cam. Google it. Great cam for stock manifolds. Sounds stock.
I tend to disagree a bit Jeff. Of course this is opinion rather than fact and my personal experience so take it for what it is.
You do lose quite a bit of bottom end with a larger cam. I have plenty of track times to prove that. I ran a best of 11.2 in the 1/8th with my 224/224 on 112 lsa without my torque converter and a 2.6 60' with no wheel spin. That is slower than stock.
A larger cam moves the powerband up. You do sacrifice low-end power. Otherwise we would all run massive cams. There are small ways to tweak this by running a lower lsa, but all in all as duration increases the powerband is shifted upwards.
If it were me in regards to my personal experience (which isn't much) I would go no bigger than a 216/220 on a stock torque converter. I realize the engine is larger than my 5.3L and the extra cubes would make that cam more tame in a 6.0, but if he has low-end on the brain I would much rather do gears than a cam.
To the OP, the cam swap on these engines is a lot easier than the 97 style engine.
