My redline is set at 6500 which is where I shift it at. I only ran it through a couple gears the night before shifting at redline. 2nd and 3rd. Yea, closed course...
The engine had 92k miles on it. When I bought the car I was told it had a larger cam and roller rockers from the dealer. I then found out it had stock rockers and stock valve springs and bad valve seals. Replaced all that and got it tuned. It has been running flawlessly ever since. Now what has been done to the engine internally I have no clue. I was told nothing. but looking at all the oil leaks this motor has coming out of every place on the motor I doubt the heads have never been removed.
I did have a forum member pm me saying he saw this car for sale in maryland just before it was sold down here in virginia. He said it was running like crap and the guy was having motor problems and couldnt get it fixed so he was selling it.

Maybe I am missing something but over 300,000 miles on any engine what would your expectation be going to redline? I think if it were me I would say thank you to the engine gods and go on my way.
I understand the constraints of money but if you are going to take out a loan to make the repairs then I would suggest a long term strategy rather than a short term fix. Just my $.02. Good luck .

I'd say go with the LS7. It will hold up to the abuse much better than the LS6. I have one in my '98 and I absolutely love it.
Are you going to mod that new engine at all? Tell us your plans!

I have been hearing that the LS7 clutch is too stiff. Are you running with the LS7 flywheel or an aluminum? I hear mixed things about aluminum flywheels.
While I am in there doing the clutch I am putting in a brand new slave and clutch master cylinder. Since my clutch now likes to stick to the floor during hard shifts.
So next year I am sending off the transmission for a rebuild. Hell I will have a pretty much brand new car then.

No sir. This is my daily driver and I want this motor to last a long time. This one is for an 04 zo6 so its 405hp stock. I am hooking it up to my TPIS long tube headers, random technologies 2.75" x-pipe and high flow cats then to the borla stingers. Putting on my ls6 intake and port and polished throttle body. Then hooking up the vararam intake. My ls1 put down 388rwhp. I am hoping this puts down something close. I am reading a zo6 with bolts on and tune get around 390rwhp. So once I get everything done I am going back to my tuner to see what it can put out.

The LS7 is defintely bigger and more forgiving if you beat on your vette occasionally. It's probably worth a second look IMO. I've heard some people have been able to get theirs to feel like a stock clutch.

Yeah, my LS7 clutch is stiffer than I would prefer. But I have read something about needing to shim the slave cylinder to make the LS7 more smooth. I wish I would have researched that when I had the engine out of the vette.

I didn't do any mods to it.
I have a brand new LS1 slave cylinder just installed and I didn't even think to check at the time, what flywheel I am using. Now, I regret not buying the best slave cylinder I could have gotten when I had the chance. From what I read, the slave cylinder usually goes bad before the clutch does with the LS7.
My clutch was installed by a previous owner...6k miles on it so far. The pedal would feel improved if it engaged a little bit lower to the floor. From what I have read, that can be solved by a shim.
*edit* There is a descrepency between the shim required by a C5 and an Fbody. I haven't been able to find out what the true shim needs to be on the C5 yet, there seems to be alot of different measurements out there for it.

I ordered my clutch with the 04 zo6 slave and master cylinders. Which I have read have larger holes. I'll see how it does with no shim. From what I read only a few add shims. So it can't be that bad without. Also just ordered a speed bleeder. Hope this is all I need. Now just need to buy new bolts.
