Turning engine over COUNTER-clockwise
Can turning the engine over counter-clockwise by hand damage the engine in any way what-so-ever? I mean is there even the most remote, trillion-in-one, see a unicorn the same day as yeti and the lochness monster, chance of causing even the slightest damage to even the most insignificant engine component by turning the engine over by hand in COUNTER-clockwise rotation?
BTW, Plugs are out.
The reason I ask is because I'm installing new rocker arms on a fully assembled motor and there is no way to get a wrench on the crank bolt with all that crap in the way. If everything was off of the motor, I might be able to snake a wrench in there but I really don't want to tear all the stuff off the front of the motor.
I can, however, rather effortlessly, turn the engine over in counter-clockwise rotation by rotating the supercharger pulley clockwise.
Thanks for the help!

It doesn't look like there is any way to snake it in there, much less rotate it with all that other crap in the way. I could take everything, minus, the power steering rack out, but Id like to avoid that, if at all possible.
Does anyone know if its possible to get a ratchet on that darn crank bolt?

I have the LS2 chain, but I remember when I put it in, it had a little slop in it, could that somehow potentially be an issue with the cam...like bumping the valve into the piston? I have a 228/232 .571/.573 112 cam.

I turned my flywheel by hand in both directions when installing my clutch. No issues at all. If I was in your situation I would definitely use the supercharger pulley. If you meet any real resistance stop, but I highly doubt you will, pistons are still going up and down either way your turn.

How many times did you rotate it CCW? I'm likely going to make 20 or better complete CCW rotations.

I don't know how you guys are claiming to use a box wrench. There is just zero room to rotate it. I do have a supercharger in the way but I seriously doubt there is enough room to rotate the wench even if the supercharger wasn't there.
I can tell you one thing, the GM engineers ears are burning right now. Seriously GM, couldn't have another .5" clearance?

I did mine without supercharger on. It's not a normal wrench. It has a good offset. You get about a quarter to a third of a turn on it. Have to do it from pass side on top.

Got a wrench on it!!!
I used a 3/8" ratchet with flexible head and a shallow 15/16" socket which I cut .5" out of. Took off the charge tube rubber tube to get access and I can effortlessly rotate the motor from the drivers side.
Never thought it would be possible with the supercharger on the motor. So glad it is!
The wipe pattern if the Yella Terra's look to be just about perfect without the shims. Cool, because I didn't want to run shims.
