Might be a bent push rod...
Pull the valve covers and you will likely find whatever it is right in front of you.
Does the engine have a hard miss? Like it is not hitting on one cylinder.Quote:

If that's what it is, I might have some laying around. I will mail a couple, if I can find them !!!
thanks guys going to look hopefully tonight...car is not drivable right now-no 3 o 4 in trans...o and it has 104k and i am doing a cam soon so not sure if i should use this block o get a new one from ts
So are the ls1's know for doing that?Quote:

Ya, The stock valve springs & push rods are the weak link... It's real easy to float out the valves, causing bent valves too... After I bent a few, I installed comp cam bee hive springs & magnum rods.
should i go with a new block when i install cam or will the stock bottom end stuff-bearing/pistons... be okay...fyi it had been running lean when i bought it and then i got it tuned by frost in 07...not sure if it cause any damage???
The block is most likely fine ! I ran my stock bottom w/ a big cam & a 150 dry shot for 4 years !!! That motor got me into the high 10's !
Actually, I got on ebay and bought a block & crank for a future build, "but", I popped my motor & am rushing the new build now !!! I'm hoping my old block is OK for a spare build !!!
Dang, I really need to use the spell ck. Sorry.Quote:

I try not to let mine rev that high anyway. Sure could use a good excuse for new head set up though. lol
If you really want a good excuse, come on up !!! I have HP tuners, & we can set the rev limit to 9K !!! LOL !!!Quote:

Wow, I just noticed that every one on this thread, besides me, is from Virginia ! Any of you race Mason Dixon ???
9k and we might be talking new motor! 6 liter here we come!!
Anything above 6k makes me nervous on a street motor, Well, except for a bike maybe.
That thing must be humming crossing the line at 7k. And sounds good too, I bet !
6800, wow. Post up a clip of that.
Here's a 11.05 pass that my buddy Mark took. Hot, Humid, & a little slower day, but still consistant !!!

Here's a 10.77 pass on Marks SS, Which also has a stock bottom end !

That is pretty close to the sound mine makes, but no bent pushrods or broken rockers or valve springs for me...I'm 99.9% sure it's a lifter in my case cause I've already eliminated all of the other valvetrain variables. My car used to make the sound only as rpms increased, but now it does so at all rpms and idle, and it's starting to miss a little.
Definately pull the valve covers and take a look!
