Re: Bleeding the Coolant System
Just about anything you want/need to know is already offered in the links posted in this 7 year old thread. My website is full of info (links above and in sig).

Re: Bleeding the Coolant System
Spend some time on Shoebox's website. It is the most complete single source on the web for labeled pictures, part #'s, DTC's, etc.
I bought my car 11 years ago, totaled, when I was 15-16? And towed it home with no engine or trans in it. Two truck beds full of parts.
Shoebox's website showed me 99% of everything I needed to rebuild the car and get everything hooked up properly when I wasn't the one who took it apart.
It has been in my bookmarks now for 11 years, across 4 computers, 2 failed relationships lol, etc.

The Optispark is the distributor. Unlike all earlier small block Chevy engines, it is not located on top/back of the intake manifold. It is mounted on the front of the timing cover, concentric with the centerline of the camshaft, and is driven either by a splined shaft inserted into the cam sprocket (93/94) or by the cam dowel pin (95-97). In that location, it is susceptible to damage from coolant dripping from the water pump weep hole, or from any water or coolant that is dripped or sprayed on the front of the engine.
The Opti functions like a conventional distributor - cap and rotor route the high voltage from the coil to the correct spark plug. In addition, there is also an optical cam position sensor that provides the PCM (computer) with the data it needs to time the ignition, drive the tach (94-97 only), and time the sequential fuel injection (94-97 only).

Re: Bleeding the Coolant System
I replaced the heater hoses on my 95 Z28 with just regular hose, no bleeders a few years ago. It took a couple of days of driving a little then adding a little more fluid but I don't have any problems. I think you are over thinking this.

I guess GM just wasted a lot of money providing the Corvette version of the LT1 with a complicated "self-bleeding" system.

Re: Bleeding the Coolant System
I wouldn't say that, I just did what I had to do so I could drive the car . I have always meant to buy the correct hoses and do it up right, I just haven't got around to it.
