And this is just plain stupid too........the amount of threads on the new longer bolt that actually go into the starter mount on the block are identical to the older shorter bolt......so the clamping force is the same EINSTIEN........
Its the starter itself that was made stronger.

Why push the redesigned starter when the starter is not what's breaking? The head on the bolt is what clamps, so how can moving that further away from the block, make the block less prone to failure? The block flange is supported in both designs, so the truck starter accomplishes nothing.
If the starter does not break where they keep breaking (the small inside tab) then the starter cannot pull away from the flywheel cause the other block mount to take all the stress from the torque of the starter. The bendix on the starter would simply fly out, hit the binded up flywheel, and stop. There would be no breakage because that inside, redesigned side of the starter is WAY TOO built up with aluminum. Its night and day difference.
All of the stress when the starter is engaged is a pulling force on that inside bolt, that outer bolt really has no stress comparitavely. It has stress of course but its really just an alignment bolt that keeps the starter lines up with the flywheel. That inside bolt is the master.
When I called my friend at Sheehan Pontiac to see what he can do for me to fix this, they said there's nothing they can do, they don't do that type of repair. He told me the reason they redesigned the starter is because they were replacing dozens and dozens of peoples blocks because of these broken starters...breaking the blocks when this little tab would break off the starter. The same thing someone mentioned on here in a post somwhere. Back in 1997 and 1998 with the new LS1's. Makes sense why they beefed up the starter. It cannot break away like that anymore because there's no way that part of the starter can break now, the starter cannot torque enough to do it, the starter will stop dead before it breaks now.

HotSilverBird was saying that if the shorter bolt is loose, or if the starter breaks at the point where the shorter bolt goes, this will cause the starter to pull away, and with that force, the mounting point on the block where the longer bolt goes will snap off. The truck starter's mounting point is the same on both sides, so it doesn't have the weaker mounting point like the short bolt LS1 starter does. Since the truck starter has the beefier mounting point, it won't break and cause the problem.
So all in all, I'd say it was a miscommunication because I didn't know you the starter broke until the 2nd page. This probably should have been mention in the initial post, but yea the truck starter should fix this. Along with properly tighten bolts of course.

I was thinking the same thing, 01ss, so I had to go back and reread through the thread. OP made it really confusing at the beginning cause he kept saying things like

Sorry for the old thread bump but I too experienced this engine block starter failure.

From what I have read in this thread, you all have made a lot of sense. I can see how the truck starter has more mounting surface and thus, is stronger. Now the question for me is, what is the part number for the truck starter? The eBay links are no longer valid. This is a great idea. I'll be mounting this on a 2001 Corvette if that matters with the starter.
