You also need the safety chain holding the engine up to prevent it from torqueing over the stand, in case you didn't notice his. Sounds great. What did the cam mod run you?

NICE!....very NICE!
when i first saw that engine was sitting on the stand and was about to be fired up, i thought it was going to be one of those america's funniest home videos type moments. i would have never thought you could safely run a motor on an engine stand.
do you have any idea what kind of power your setup wil put down?

I did the same... after a few swaps I decided it's better to get things sorted on a stand rather than in the car.
I used a small, sealed can w/ a Bosch fuel pump in it wired and plumbed. Worked well.
What sort of RPM range do you expect w/ that Z06 cam and a 5.3?

It is a very common upgrade I bought it used off of ebay gm part number 12565308. To supply the engine fuel I used a pressurized fuel injector canister that I got from my friendly mechanic. All you do is put fuel in the canister and pressurize it with an air hose. I am hoping to get a max rpm of 6500 with this setup. I you do decied to do this cam swap be sure you swap valve springs. I am using the yellow ls6 springs.
