Default Turning the engine over by hand

Anybody got a good way to turn the engine over by hand with the steering rack in place from on top so I can see a dial indicator on a valve. I can do it from underneath, but then I need two people. I was thinking of making something, but it's a pretty tight fit. I do have an ARP balancer bolt so it's a twelve point.

I made a tool by shortening a socket about 1/2", and welding it to a pc of flat stock....looks like this:



This will work on a stock or Powerbond balancer, where the front of the pulley is mostly open, and there is room to slip the socket in between it, and the rack.
But on a closed-face balancer (such as the ATI), there's just no room to get anything on the bolt head with the rack in the way. In that case, you can use a non-metallic strap wrench wrapped around the balancer to turn it over.

I made something similar for the stock setup and have one that works for the ATI I have installed. Its ugly but works well.

I like that tool. It doubles up as an attitude adjuster as well.

Remove the spark plugs and belts, then use strapwrench or even hands?

Should turn over easily once you remove the compression.

I just use a box end wrench on the ARP bolt, it sticks out far enough to do it without a problem

I have snap-on and proto and both work fine. The box end is at an angle and it's enough to get on there great

Automotive Racing Products (ARP) makes aftermarket fasteners and in particular they make a reusable bolt for the harmonic damper (pulley) on the LS1 motor.
