Hey whats up everyone. I've been looking into a cam setup for my 98 ls1. My question is, Is it safe to do a cam install with 86k on my motor. Keep in mind that I plan to install a new cam, springs, rods, retainers and possibly a better oil pump. Is this install doable on my car is it to much of a risk to the rest of my engine with the 86k on it already. I've seen plenty of cammed ls1's with over 100k but I assumed they were cammed at a much earlier point. Lemme know what ya'll think...thanks in advance...josh.

A friend of mine had his cam installed and tuned at 120k miles. You're fine.

Check the leakdown and compression. If those are fine <30% on the leakdown and compression within say 3-5% across the cylinders, then you should be fine. I'd go for the new oil pump, a new timing chain, new pushrods, and new lifters.

I just did a cam install at 74k, and this car has been run very hard. It's holdin' up like a champ so far, and it's not even tuned yet.

Oh, you probably want to replace the stock rod bolts with ARP or Katech bolts if you want to spin it close to 7k RPM.

also this will be and is currently a daily driver...so i mean its not like it will be run all that hard besides the once or twice a day burning of tires or something...well thanks for the responses because now ive got a better feeling about going through with this...j.g.

Go ahead and mod the car..86k means you got it broke in..

yup definatly what he said. You have weaker rod bolts than newer models, So I would replace those. Better to be safe than sorry. and also get the ported oil pump.

I would also look into replacing the rod bolts if it will see 6500 - 6600 rpms or more. Get a ported and shimmed oil pump. Get an LS2 timing chain. Replace waterpump and front cover stock (paper) gaskets with newer metal o-ringed ones.

Cam it! I just rolled over 100k, and I decided I will be doing a cam swap this fall with the Torquer 2. I wouldn't worry about the rod bolts. Many people with cammed LT1's spin theirs upwards of 7000, and those motors hold up fine having not been apart. LS1's have a stronger bottom end, so as long as yours is in good shape, don't worry about it. The fastest cam only M6 car in the country is a 99 with a T-Rex cam from Thunderracing. However, I will be replacing the lifters as I intend to go with PRC dual springs. You might want to consider doing that.

Ok this question is pretty similer but i have a 1999 trans am with 124,000 miles on but i do plane on getting a cam & head package with a new oil/fuel pump and a new LSX fast intake w/ 90mm TB and new headers and i plan to do all this at the same time iam gonna save up and have it all installed but not before i buy bolt ons first.

What should i do to the engine after the bolt ons cuz it has 124,000 miles.

Thanks all of you.
