What lash cap? To be cautious, I would replace the springs and check pushrods, and rockers carefully. I'm on the strip almost every week.

Or a valve spring that has lost it's tension from an overrev can cause valve float the next race and cause piston to valve contact destroying a motor.

Power shifting a 4+3 or even a ZF box for 3 years and I'm guessing this 4+3 has been rebuilt a few times? I only ask because my impression of a power shift is straight gorilla arming the shifter into the next gear without a clutch pedal. I have heard this was how John Heinricy was able to get a 2002 Z06 to 60 mph in 3.9 for the marketing. With the T10 gearbox I guess the replacement parts would be cheap enough where it may be worthwhile..

Its smoking quite a bit now on startup, but other than that it seems just as strong as before.
I took it to 1/8mi no-prep last night and it ran great - just no traction available.
We will see how long it lives.

Hell yeah, I can't wait to get my LS fired up and bounce that bitch off the rev limiter at 2 am on a weeknight. Hope my neighbors like the sound of my ****** Chevy
