so i was taking the car out for a stroll, missed second gear. tach reads 6700 rpm. this is a bone stock zz3 crate 350 with pro magnum roller rockers. it sounds fine, but i just want to see if there is anything that i should pay special attention to. i am pulling the valve covers tomorrow. what is the possibility of damage?

im not sure what all could be hurt,but i did the same thing a couple years back when i was running my 4 speed( a few times)

only once did i damage anything,and it was only 3 bent pushrods...

Unkikely there is problem at all. A smallblock and 6700-6800 for a milisecond doesn't equal disaster even in stock form. If you want a comfort factor, do a compression check and take a look at the valve train for bent pushrods / broken springs. But if the motor is sounding and running fine,, I'd not worry about it.

Things should be fine. A friend of mine had a new 355 built for his Camaro, and the builder dynoed it at 7200 rpms before it ever went into the car. He runs 4.56 rear gears, so it sees those kind of rpms everytime he runs it on the track, and it is OK with it.

When my car was still a 4spd, I had it twice pop out of gear when I was running it hard. Once was on the chassis dyno & it hit 7200rpm for a brief moment.
Everything ran fine afterwards & on teardown a few months later there were no signs of damage.
I did fix my shifter linkage right away though.

If there are no strange noises or oil pressure changes, the engine should be fine.

Unless you are having running problems I wouldn't worry. 6700RPM isn't all that high.
The Stock 1970 Z28 had a 7000RPM redline.
The motor probably does not make good power up that high, but I doubt you hurt anything.

If you did any real damage you would already know it..

like the other guys said 6700 rpm aint all that high for a small block.

I take my cast crank, GM rods, hyper pistons 355 to around 6400 rpm on the 1-2 shift every time I drive the car (and it's my daily driver)

Once I took my old bone stock 305 to 7000! Stock cast pistons and all, and zero damage. Ran great for another 10+ years http://www.nastyz28.com/ubb/wink.gif

With all due respect to what everyone has said about how high they reved their motors to....

It all depends on how good your valve springs are. Stock springs can take a rare quick rev like that, but if your springs are weak to begin with, then there might be trouble. Of course, better springs are built for higher RPM's.

Did the valves float?

I believe the ZZ small blocks peak power was around 5500, so revving past 6K would be useless, except in your case where it was a boo boo http://www.nastyz28.com/ubb/wink.gif

The bottom end on a small block will take the higher rpm without problems. On the other hand, if you float the valves the springs will wear out much quicker. As a matter of fact, every time you float the valves they will float at a lower rpm.
If the vavles did not float then you don't have to worry about it at all.

Does that have screw in rocker arm studs? I've seen pressed ones pull out enough to loosen the lash.

To my knowledge, and I may be wrong, but all ZZ engines came with the L98 Vette aluminum heads, which are aluminum with screw in studs and guideplates.
