i have a 2001 rcsb with 5.3 all stock, what is the biggest and best cam i can put in my truck with out having to change anything else on the motor just swap the cam and thats it is there any like this or do you have to do anything else after you have swaped the cam out?

 

I think with any cam swap you will want new springs at least. A mild cam that gives about 30 more HP is the Comp 212/218. Its rather mild and will be ok with stock tuning. May have to set the idle up a little, but thats free.

 

Get a 2000 Fbod cam, Z cam. It won't require a spring change and it has a good amount more lift than the stocker you have. I don't remember the numbers exactly but I do know that .500 is the max you can go with stock springs.

 

isnt the 2000 F-Body cam .500?

 

LS6 springs are pretty cheap anyway, and easy to change. And would work with the 212/218.

 

Crane does a cam that works with stock valvesprings it's 208/216 .500/.500 114.If you want to go with stock tuning and just slip in a cam that would be the way to go.The power increase should be a lot better than adding a stock ls1 cam.

 

thanks for all the help

 

can some one give me a link to the comp 212 218 i went to comp web site and couldnt find it

 

It is a little easier to go to www.racenet.net and look up under the Avalanche section, then the engine section.
It will give you all the cams, springs, retainers, lifters, rockers concerning the nbs trucks.

 

If your going through the trouble of a cam swap especially on a reg cab 5.3, I would not waste my time with anything under a .520 lift. That 212/218 they are talking about is an 212/218 .522/.529 114 Comp cam. I have one with Comp 918's and hardened pushrods on my 4.8. Now my tunning is off (due to my communication problems with LS1 Edit and the PCM), but with a 5.3, you should be fine.
