my 5.3 has around 225K miles and i just acquired a 212/218. I plan on running yellow springs and 7.4 pushrods. But my question is about the timing chain and revlimiter. Will the chain be good enough to leave in place? Plan on shifting gears at about 6200 rpm, is that to high or not enough. Don't want to turn the bottom end harder than I have to.

Ive searched some but there just arn't many threads about high miles and camshafts.

 

I'd replace the timing chain just to be safe. 6200rpm is about right for that cam, mine is set at 6300.

 

The stock chain lasted to 250k miles for one guy on ls1truck.com. He had a cammed 5.3 and beat the crap out of it. I say change it just to be safe.

 

Yank is selling LS2 HD timing sets for $65 shipped. Might want to send them a message and see if they have anymore left.

Or... sell me the cam
I'm on the hunt for that cam.

 

^^dude on gmfs has same exact cam for $150 shipped

edit: he sold it

 

Dammit.. as you can see from my siggy, I'm close to acquiring all of my parts. lol.

 

i have an ls6 cam im wanting to get rid of, but have to find a suitable replacement to go ith my tb stall and 456s

 

The LS2 chain is $45 shipped from GM Parts Direct, FYI. P/N 12586482

 

long as the motor has been kept up and has no known issues i say your good.
I would replace the timing chain just cause you already in there

 

I bought this cam off of GMFS lol. The engine is in good shape, 90% of the miles are 75mph on the interstate. I guess I will change the chain while I'm in there, and turn it loose.

Greymatter where are your shift points set if you don't mind me asking?
