Just wondering what Ideas the more experienced might have. My new truck is a 2006 crew cab 5.3 with 4l60 3.73 and a g80, and aftermarket muffler. I am looking to get better fuel mileage and better power. I will be using this as an everyday driver and also to pull my single cab to the track. I am more concerned with the over all durability of this truck, but I would like to make it faster. I have all ready ordered long tubes and off road Y, CAI, and I am working on getting EFI live and a tune from black bear. I am interested in putting a cam in latter on but I would like to keep the stock converter or at least a full size in order to keep my pulling ability. In the cam I am looking for good power and good sound. I now it sound a little strange but I want a nice choppy idle even though the trucks a log. I have looked into the comp cams thumper series do you guys have any suggestions?

 

if you will be towing and it's a crew cab...keep it somewhat on the small side...no bigger than the 212/218 grind, I would even go smaller I think for what you are looking for. 206-210 range right in there somewhere

 

I agree w/ sonoma43. A Comp XR259HR (p/n 54-408-11, 206/212 duration) would be good for what you are looking for. If you wanted to go little bigger, the XR265HR (p/n 54-412-11, 212/218 duration) is a really good cam, also. There is a thread posted by NicD (see link below) for this cam that showed really good numbers for a 5.3. No loss on the low end w/ good gains through the mid & top end. Good luck

yea this is why I like others in put, any idea if the 212/218 will provide any change in sound? I want the truck to have the cam performance sound. I know that sounds stupid but it's just something I was looking for. The over all performance is most important but if I can find a mild performer that bumps good I will go that way. Keep the info coming. I have never owned a crew cab so I under stand the lower side of things because the extra weight.

 

the 212 218 is a great all around cam.. out of 212/218, 222/222, and tr224 cams that i had in my 5.3 i liked the 212 218 the best

 

There isn't a bunch of overlap, so you won't hear it much, but a trained ear will know it's in there. Sounds like a good cam for your application though...if you really want sound, just set the idle really low. You can still tow with certain aftermarket tq converters, the YankTT2600 comes to mind. That converter would compliment that cam very nicely IMO.

 

heres a 212 218 in my 5.3

 

what lsa is your cam on?

 

that cam was a comp 212 218 .522 .529 114 lsa
