What else to replace when I put in my new cam?

[odie301]

ok looking at getting the comp cams cam #54-424-11. I believe it is the high lift version of the 54-412-54.

Any way looking at what else i need to install.

Hardened pushrods. are they 7.4" long still?
New valve springs. Do yellow ls6 springs work w/ this cam or do i need more?
Timing set. Is a stock one ok or do i need a "true roller"?


Anything else while i am in there?

I called and asked them. Or you can use their program that gives you what else is needed with the cam you pick out.

Don't forget all new gaskets, I know its common sense but sometimes you forget the simple little things.

 

[odie301]

yep, gaskets were on the list. Still trying to figure out if stock timing set is ok..or if a person "really" needs a performance one. Not sure what could be all that different about them other than price and material they are made out of.

How many miles are on yout chain? I would at least go with an ls2 chain, you also need a new crank bolt, fluids, etc.. Good time to do a tune up also..

LS6 springs are good to .550 lift. thats cams probably 529 at most.. Would be cutting it close. If it were me I would run at least a beehive spring at minimum.. Something like a comp 918 or pac1218! Pacs are my preference.. Had good luck with them and manleys..
If you want good prices on those items let me know..

Also pushrods should be a 7.4" go with chromoly lke 110 bux...

New crank bolt for sure. The bolts are torque-to-yield, which means once they're torqued down, you can't reuse them.
Depending on your mileage, it may not be a bad idea to install a fresh oil pump and a double roller timing chain since you're already there. Only a few more minutes of time.
7.4" rods and LS6 springs should work with that cam with the stock heads.
When you remove the front cover, stuff a rag at the bottom where the inside of the oil pan becomes exposed in case you accidentally drop a bolt or something, that way nothing ends up in your oil pan that shouldnt be there.

CAMS RULE!!!!

Your gonna love it!

 

[odie301]

Can someone explain the difference in timing chains/gear sets?? What is a true roller, vs what was in a stock motor? How is it better? Just asking cause i dont know, and because of the price difference.

The cam i am looking at 54-424-11 has a valve lift of .558/.563. (1400-6700rpm range)so will LS6 springs work or not?? The ones i saw were the yellow beehive style, they said good for lifts up to .580 they gave a GM part # of 12586484. And said stock retainers work with them..? Not sure if that is too close to maximum for comfort or not.

I am just looking at these options to keep this on a budget...if i had tons of money laying around i would buy the whole kit from comp.

Anyone know someone running this cam? I would be very interested to hear how it does

 

[viximaging]

You can run the ZO6 springs.. No problem. Just purchase an LS2 timing chain. All you need, its stronger then your stock unit... Springs are like 80 bux and chain is like 60 from texas speed ship same day!

i would run theses though

And DO NOT FORGET CRANK BOLT!

if you check around you can get better pricing on the pac 1218 and the 1518 I believe. but those are the parts i'm going to be running i believe

 

[Nickleahy23]

good thread...i hope to scoop a cam and get it done once i start workin this summer...if not sooner...cant wait

 

[yooformula]

if you are going through it all yourself, might as well install a new high volume or ported oil pump, swap in e-fans while you are at it and maybe a underdrive pulley set.

 

[Tahoe03mm]

is a oil pump really that necessary? especially if it has lower miles? I have the heads off and i'm replacing the timing chain so I suppose I might as well

get a ported performance pump or is it going to matter?

[Tahoe03mm]

I'm looking into pumps too, from what I've read shimming does nothing.

[odie301]

Does the LS2 timing chain use the same stock gears that i already have? Or should i get a whole LS2 timing set?

 

[viximaging]

Yes it will work fine with your stock gears..

Great Thread!

I just bought a 2000 Z71 / 5.3 and am doing a cam swap.

I Talked to my Friend Zippy ( Zippy performance) ( he's on performance trucks .net) and He reccomended a 220-224 ( which is a Trick flow) grind cam for my truck.

He has dynoed a stock 5.3 with this cam, corsa cat back exhaust, Tune, cold air intake .

Made 309 horse at the rear wheels! Stock is 240 at the rear.

Like i said earlier cams are awesome!

I was Told to get push rods, oil pump, timing chain, and a new water pump. ( my truck has a few miles on it.)
Seems the 5.3 water pumps usually go at around 90,000 miles according to my friend who is a service manager at the chevy dealer.

Zippy also sells a trailblazer torque converter, they are made by precision industries for their industrial line. They stall around 2500 and are only 200$ !

Zip told me he has sold about 200 of them with only one failure( guy beat the shit out of his 500RWHP truck) But said they are holding up well behind Radix supercharged trucks. Im going to try one.

I had a friend run the 224/224 with the TB stall in his formula, kept up with my GTO with alot more mods!

oil pump is cheap insurance especially for the year. My 99 LS1 had intermittent oil pressure issues and yes it was the o-ring but for the money and time, it was worth a replacement especially for a ported LS6 pump. a bit of overkill but I also changed out my timing chain to a double roller and got rid of the stock lazy lifters.

I think a torque converter may be in near future though after reading Tim's post!lol
