trying to deciede
 

ok so im trying to save up enough cash again.
after buying my 5.3 and 4l60e if i should get a tune.
and goahead and get a cam for it or wait and just get a tune.
or not even get a tune funds are way limited but i do have a DD.
i kinda want this as my street cruser

Re: trying to deciede
 

Get a cam!!! :lol: In all seriousness(is that a word?), if you went ahead and installed a cam, then you only have to have it tuned once. LS engines like more cam, too. On the other hand, stock valvesprings don't like to be revved too far past 5200rpm, so new springs are recomended with a bigger cam, and depending on lift, maybe new pushrods. Being on a budget, the cam upgrade can get costly. A good ECM tuner will usually only charge once for an initial tune, then give free upgrades and retunes as you make mods or changes to the engine.

wait for the cam (and do springs and pushrods at the same time), then get it tuned.
No matter what, it will get re tuned eventually. I'm going to be on my 4th flash, and I haven't even gotten to adding the forced induction stuff yet.

I used Nelson out of San Antonio and when I changed rear gears, they are sending me another PCM with the changes for shipping only.

Re: trying to deciede
 

yeah i will use nelsons they have a good deal its like 300$ then free for nay upgrades.
im thinking of the tr 220 cam ill have to find the link i think it said it dont require a stall.

i broke myself buying the motor and tranny but i got the harness and ecm and stuff.

Re: trying to deciede
 

I would cam now if you have the monies... but most cams require springs retainers and locks, sometimes pushrods and lifters depending on the cam you choose. So a $200 cam can cost alot more. I know Howells will reflash if you change tire size rear end ratio for free all you have to pay is shipping. Not sure if they will reflash the rest for free. Its worth calling around to see what companys will do for you.

Re: trying to deciede
 

any suggestions on cams? kinda want one that dont require a stall if at all possible

Re: trying to deciede
 

if you can't spend the coin for the pushrods/springs/cam support stuff, don't break yourself again on the cam. Buying a small cam that doesn't need a stall or the supporting stuff usually means smaller gains.

If you really want to do one, why not try something like the 'vette cam takeouts, you can get one and springs for a good price used, it will give you some gains, and its driveable on a mostly stock setup. Plus its cheap :)

Re: trying to deciede
 

ive considered that push comes to shove i find something i like ill buy it.

and to note i know ill need new pushrods and springs not sure if this is correct
some people use the ls6 springs?

Re: trying to deciede
 

From what I've been reading, the LS6 springs are a good upgrade for stock cams. For anything more than about .550 lift, they're not that great. If you're going to upgrade, go ahead and get some good dual springs.

Re: trying to deciede
 

no stall cams would be in the less than 218 duration intake side.
I am told a 224 works but I dont think it would drive very well in stop and go.
I have a 218 to go in my 6.0 when I find the time.

Re: trying to deciede
 

ive heard good things about this cam here
Comp cams 216/220 .525/.532 114LSA
stall range is 1300-6300

Re: trying to deciede
 

I've got that 216/220 low lift cam setting in the garage waiting to go into my 08 silverado. From what I've read it gives gains in hp without killing lowend torque. You can also use the ls6 springs with this cam. The 212/218 is another proven cam. If you don't put a cam in it before you install the motor I'm afraid you will be sorry. A cam really wakes these motors up.
