You guessed it! Snapped f-body starter #2's case also!!?? F$#@%! I don't know if i should skip a truck starter all together and get an MSD billet one or what? 2 in a row without braking the block has me a little worried. The truck case will probably not give at all. I've checked everything and all looks aok...
How is the MSD starter going to be any different though?

I would verify every single tooth on the flywheel is in good shape, if that looks ok I would toss that particular starter in the recycle bin and get the truck starter with the 2 long bolts, my 2006 GTO LS2 starter also uses 2 long bolts.
I think GM knew there were issues with the 1 long and 1 short starter noses hence the reason they went with the 2 long bolt style starter noses. There are quite a few threads on here of where people break a chunk out of the block instead of the starter nose, I think it's mainly on the aluminum blocks though. I think you are playing with fire, the next time you may not be as lucky and will end up with a piece of the engine block in your hands instead of a piece of the starter nose.

Well he says he's at 13.8 on compression that is up there, and as I said in my post above if everything looks fine on the flexplate, I would toss the starter in the recycle bin and try a whole different starter and if I am going to replace the starter, might as well replace it with the better 2 long bolts style.
If I read his posts correctly he only replaced the starter snout and continued to use the same starter body, maybe it's just me but I wouldn't trust anything on that particular starter anymore, 2 broken snouts? And no broken block yet? I just wouldn't take a chance like that using the same starter.

I am at a total loss for words right now. I put a new truck starter in after checking EVERY single tooth on the flexplate. I checked for loose bolts, watched flexplate runout, ect. ect. Went to fire the thing and heard the dreaded noise and went OH F%$#@! I figured for sure i had a broken block this time. I went under and checked the starter and all seemed super tight!?? Took out the starter and holy sheet, the snout broke clean off and fell inside the bellhousing.

Where is your ignition timing at? Too much timing will break a starter every time. Had a friend break 3 in a row, due to too much timing. He was at 15:1 compression and really pushing the timing to the edge. He backed the timing down a fudge, and he's been good to go for a couple years now.

Clearly something else is causing the problem other than the starter itself. I would start with the flexplate and make sure it's torqued to spec. Almost sounds like it's warped (if that's possible) and jamming into the starter teeth. Remove the starter and crank the engine by hand and watch the flexplate to see if it rotates freely without binding.

If you broke that truck starter with the two longer bolts, something inside is hanging the rotating assembly up.
Maybe take out all 8 spark plugs and see if it turns over easily. Just to see if when the starter hits the flywheel its not causing the binding. If it binds with no compression on it, its the flywheel.

I would take the trans out and take a look at that flywheel. I know its a pain, but its better than the block being broke off. Also, that SFI **** doesn't carry much weight to it. I had a Hayes SFI flexplate shipped to me and put it on the car and it vibrated violently. I took it off the car and it was warped. I went and got another one and the same damn thing. I ended up putting the stocker back on and havent had any trouble since.
