Ive been speaking with tick performance and just got to wondering would it make more sense to get my 99 SS with 116k rebuilt im wanting the polluter cam installed and few other accessories. or would it make more sense to get a newer engine in the ls family? just curious and open to a few ideas
thanks

I often thought about the same thing and I would go with a stroked LS2 crate short block.

I looked at Scoggin Dickey, Texas Speed etc. also I googled and came up with other places. I'm sure other people will recommend other places.

What should be the compression on a ls6 block

allout06

depends on what your wanting to do... are you asking what the stock compression is?

No reason to do anything with the engine itself, there is nothing wrong at all about installing a cam at that mileage. Many many many people have done heads, cam, spray, you name it... with that many miles or more.

sweet i think ill just go that route being its cheaper than buying a new one.

I would do a compression test to check your engine. If it's good and so is the oil pressure I don't see any reason to have it rebuilt unless you are wanting to put forged pistons in it or stroke it. Just my .02

If it were me. I would go all new shortblock and build around the goal on mind. I just did heads cam lifters etc at 112k and spun a bearing. Now building a 370 for boost. Couldn't be happier.

Bearings don't spin because you did a cam, something else is wrong. The most common problem is people raise the rev limiter too high and the rod bolts stretch.

Rebuilding won't help with that issue either unless you do stronger rod bolts and/or forged rods.

Lot's of bad info in this thread.


OP to ease your mind call one of the sponsors here that do swaps all year long and ask them if they have any problems...


Here is a thread a couple down from yours, more people chimed in on how they did cam etc at higher mileage and have no issues. With the setup you are going to go with, RPM's or a poorly put together setup is the only thing that is going to break it.

Also why the polluter cam? What's your power goal and how much are you willing to spend? If I were doing a cam that big I would be also looking into heads, intake etc to support that cam.

You can always do like I did and buy a new block and build your own stroker motor. I payed a machine shop to machine the block for me then I did the rest.. My motor is going to tune next week. I built the entire short block for just under $3500.00 including machine work.. BTW this was the first engine I've ever built but I didn't just throw things together. I made sure I did everything right and checked all 3-4 times after doing it.

If you plan on keeping the car then its time for a rebuild. The lowest I've been quoted for a head cam change is $1900, SD sold me a new 2004 CTS-v LS6 longblock for $3245 (12-12K warr.) with the updated rod bolts, Timing chain etc. shipped (only about $1300 diff) and with some minor tweaks and a great tune it's putting down 390rwhp.

You put a cam in you will spin it harder, You spin it harder it will break. With just boltons F body LSx's seem to have major problems @ around 165k = Oiling, seals, bearings etc. Mine let go at 167k.

I can't think of anything LSx parts wise that did'nt get better after the LS1 Not that the LS1 was bad but alot of advances happen in 12 years.
Just my 2c.

00pooterss.... yes I know what u are saying. I never said that was the reason I just simply stated what I had happen. Im just saying with that many miles if you have the.money put in all new **** that's all.

After seeing what my bores and bearings looked like in the 130k mile lq9 that I rebuilt, I wouldn't hesitate to run a 100k+ mile ls after a quick inspection.

This is one of the dumbest posts I have ever read. I make around 360 to the tires and have a big stall and gears. I have beat the crap out of the car daily since I owned it. It now has 188k miles and the motor is still a beast. And you DO NOT SPIN IT HARDER BECAUSE YOU PUT IN A CAM, you spin it "harder" if you raise the rev limiter, the answer is so blatantly simple DON'T RAISE IT!! If you do only raise it a little. And if you have to raise the rev limiter to make power with the cam you put in then you bought the wrong cam for your setup! Pic a cam that works within your RPM/setup limits.

That being said mine is set at 6800, quite a bit higher than necessary and it still has no issues, but im not in here spreading incorrect info about what blows a motor either. I know I may pop mine due to the raised rev limiter, but I accept that.

Sure if you have the money then why not, but it is in no way needed.

Winner winner chicken dinner!

well what im getting done is the polluer cam new intake new chain full exhaust headers all the way back. just want the car to sound and run alot better. car will not be ran at the track or anything like that. i said the polluter cam just because thats what was recommended to me

I put a torquer v3 cam in mine at 107k with no problems. Throw In a ported oil pump while your in there. I did and my oil pressure raised by about 20psi. I'm also going to be installing a D1SC procharger at 8psi on and the car has 111k on it now. So **** it. If it blows up, rebuild it then.
