Question about large cam, s2 heads, and revving while cold. Specs:
232/228 .595/588. 112lsa cam
Patriot stage 2 5.3L heads
Is there any documentation about revving a car's engine when it is bone cold that it could cause spring failure. The best info possible would be directly from GM but I doubt they would write anything like that since they use fairly small cams.
The dealer stated he wanted something in writing about it- he said he had his best tech guys look at it and thinks that revving the engine cold didn't cause any of the problems. I said regardless of what they said, revving a cold motor cold is not good for it no matter what type of engine or specs. I also stated that I observed my car being revved beyond what it should be while coasting (~6krpms) and that very night my springs broke. I am confident that because of what the dealer did, caused unnecessary stress on the springs making them more brittle and more susceptible to breakage from the events earlier that day. I didn't even take the motor high when the spring broke, it broke on startup. So anyways, ls1tech guys, where can I get some documentation of this? Would patriot be able to put anything like this in writing?
Thanks guys for the help

p.s. - I hate dealers, they suck.

What kind of springs are on the heads?
I know that when my motor was cold with an old batch of 941's it snapped one pretty quick, all I did was start my car right away and drive......maybe the highest I got it up to 2500, then the chug chug chug and SES flashing started up.....

severely for gaskets and some labor. Anyway, I'll look for the # today. At least with you documenting a claim, they get you and the delearship on the line, then the customer line acts as arbitrator to get a good understanding of the situation. Like I said also you get a documented claim to use for future reference as well.

Overcharged...I would say so. There are no gaskets involved on a clutch install 
"My problem had to do with a "warranty" clutch install. I was overcharged severely for gaskets and some labor."

Be careful quoting this. It's not really 100% correct "materials science".
Buzzing an engine to 6k immediately after starting it when it has been sitting at 0*F probably wont' help the springs, but that wil be the least of your worries! Springs get to temp pretty fast, even at idle.

Can't find the phone #. You can get the customer service line # if you ask a dealer other than the one who's involved (imo). Best of luck!

Any motorhead with 1/2 a brain knows that you must warm up any engine especially a high powered/modded one b/f driving it aggressively, if you want to maintain it correctly and not risk breaking valvespring and other major components of both your valve and drivetrain. The dealer is FULL OF SHEET!
