The flywheel is mounted to the crank with 6 bolts. Luckily I've taken pics and video all along the way. This is a pic of the end of the crankshaft while at the local Chevy dealership showing how the pilot bearing was bored into by that oversized Pfadt driveshaft.

BTW, the above pic shows why techs should NOT use the hydraulic pressure method of removing the pilot bearing on LS engines. See that plug behind the pilot bearing? There is a good chance that would get pushed into the engine before the pilot bearing would be pushed out. Then you've REALLY got a mess to deal with.

The flywheel will have to be pretty close to the one already in there, at least
in terms of pilot bearing diameter, and depth, or you're liable to need a new
torque tube (to match up with the new flywheel) as well !

From what I can see, the LS6 and LS7 flywheels both have 6 bolt holes for mounting to the crankshaft. However, it appears that the LS6 flywheel is uniformly flat across the surface facing the pressure plate, but for the LS7 pressure plate the bearing surface is recessed. Regardless, I will have both flywheel replaced along with the clutch. For one thing, a resurfaced used flywheel was put in there, and from what I understand the GM service manual specifically states to DO NOT resurface the flywheel for reuse.

As for a possible torque tube issue, the torque tube mounts to the bell housing. It appears to me that the end of the crankshaft will take both the smaller LS6 style pilot bearing or the larger LS7 style bearing. As I mentioned that implies to me that the input shaft to the torque tube must be different in the LS6 and LS7 powered vettes. It would have to be shorter in the LS7 in order to use that larger pilot bearing.

If you look at the pic I posted above, you can see where that larger LS7 style bearing would be pressed into the end of the crankshaft.

Here's a video of someone removing an LS3 pilot bearing, which appears to be that same larger style bearing.

Now, honestly, exactly what years and which exact vehicles used one type of bearing or the other, I really don't know. But I'm guessing putting the wrong style pilot bearing in could cause you a bunch of headaches.

Default 7 Things You Should Know About the RHS LS Block

Well, it certainly looks like the RHS block in my engine is a quality piece of equipment.

It sure looks a lot better done than that original World Products Warhawk block I got.

All I can say is that I certainly was NOT impressed with the Warhawk engine I got and ultimately rejected.

So I was sitting on the "throne" listening to thunder getting closer and closer and wondering if I should shut off the computers in case the house or power lines would get hit by a lightning strike. Then that led to me thinking about the possibility of the garage getting struck by lightning and what could be damaged in there. From there I recalled that twice, buildings that the blue C5Z was in, got struck by lightning. Which at the time had me wondering if perhaps the car WAS jinxed and God was trying to tell me something. But the car has been in my own garage now for almost 7 years, with PLENTY of lightning storms during that time, and nary a one has hit the garage with the C5Z in it. Interesting, no?

So what two buildings DID get hit by lightning while the C5Z was in them? The shop owned by Chris Harwood at XtremeMotorsports and the shop owned by Aaron Scott at South Georgia Corvette. Both suffered damage to their equipment in their shops from the lightning strikes, yet no damage to my car. So perhaps God WAS trying to tell me something. Sure wish I had listened.

Of course, it COULD have just been a coincidence.

Darn.... Moved the C5Z out of the lift bay so I could move the Jeep into it so I can do an oil change and tire rotation and noticed that the fuel gauge on the C5Z is only showing about a eighth of a tank of gasoline remaining. Got to get it out to fill the gastank up before it evaporates down to being empty on me.

Didn't hear any drivetrain squealing pulling it in and out of the garage. Sure do wish that car would go ahead and HEAL itself.

Filled up the gastank on Sunday. Then drove to the post office. Didn't hear even a hint of a drivetrain noise the entire time. Maybe I scared it putting the car in the bay with the lift for a while.
