your friend,

welcome. :wave:
I'm not that hip on cams but I think a 2002 or newer Z06 cam is probably what you're looking for with the Z71.
welcome bro, lots of knowledge here just ask arround.
:smile:You had to come here and ask the cam question? Hope YOU are ready for questions about what your plans are and :blahblah:, but that's why your here right... Welcome! got:pics:. *SEE, they were all over that one. Sick'em*
thanks, i've been thinking of letting a local speed shop here in town custom grind me one and do a tune i've herd a lot of good things about them. i still would like to upgrade my pushrods and rocker arms, i don't want to have to change out my tc thought (03 5.3 ) sorry no pics yet my little bro put her in a gaurdrail last week but i should get her back next week i'll snap some pics then, curent mods coolant bypass, k&n fpk2 intake, descreened MAF, planned mods dynatech headers,high flow cats, y pipe into a complete magnaflow cat back split duals 05' dual electric fan swap, underdrive pulleys(any ideas on brand for the pulleys?) and a tune after the cam.
Do NOT get a custom ground cam unless they will give you a 100% replacement warranty for the cam, lifters and labor to replace it should it fail. Cams are heat treated about .050" deep from the surface prior to final grind on new blanks. When they regrind a used cam to your specs, they usually grind through the hardened section of the material and get into the soft area causing early failure and great expense on your behalf. Get a new cam from a reputable company or a stock replacement unit. :twocents:
welcome to the site...wut Red said buy a cam new, you never know wut can happen with w regrind cam...
Welcome to the site!!! You might want to start looking for a torque converter.
welcome does p cola stand for pensacola im sure it does but theres a town here called pacola.
Gary...what you just said should have never been said. Keep those thoughts in that small brain of yours. :)
Welcome to the site man!
Cam swaps? What is that? I don;t think we've done any of those... :haw:
Hmmm...a streetable cam for a Z71 that will run good on a stock TC. Well, you will probably not want to go any higher than a 220/220 .550/.550 if you wanna keep your stock TC. Maybe a 216/218 .525/.529 114 LSA. That might if your needs well...
Do some Pacesetter Long tube headers that are ceramic coated and use the Pacesetter y-pipe as well.
As for the UD pulleys, make sure to get the harmonic baslancer as well as the alt. pulley. ASP and MotoBlue make some for our trucks.
Hi and Hello!
dang i never thought about the the custom cams like that, that would have really sucked. hey i've seen a lot of guys on here talking about the z06 cam swap with the springs, pushrods and all, would that be a good way to go? i really don't want to change my tc but i am going into the tranny this summer and doing al little r&r and sum much needed beffing up thanks on the underdrive pulley info, do need to change my p/s , waterpump pullies to? or should i be good with the alt and crankpullies? ......bty anybody got a set off 05' 06' stock electric fans they might wnat to unload?... ohhh almost forgot what about ls6 heads? will they swap right on my 03' 5.3?
thank you
Yes they will! And those 243 heads will flow awesome!
any certian casting #'s i should look for? i know the z06 first came with 385hp but then they up'd it to 405hp i guess i want the later heads, know anybody you would recomend to get a complete z06 cam kit lifters, springs, pushrods,etc? bty thanks for all the help guys (and gals) i always like to learn all i can about something before i do it
Like I said--243. That is the casting number for the Z06 heads. You can find some good deals on Z06 valvetrains on Ebay...
oh ok cool, yeah i need to start checking on ebay thanks man
