I joined the Club!

100k miles is nothing for a hemi. I might pull it apart and replace a few thing in the top end. (valve stem seals and springs) but the bottom ends last a long time. My buddys 05 has almost 200k on it and he sprays a 150 shot and his 4 door truck runs a 12.3 in the 1/4

I don't know of anyone that has worn one out yet. Failed sure but not worn out. The motor I have has a bigger cam and ported and polished heads on it. And when in the truck made about 370 to the wheels with a 28% driveline loss. (thats without nitrous) so that should be about 470-500 at the flywheel. Now add in the 150 shot and it should be in the 620-650 range. So even without big money it can be fairly easy to net 500 hp in the hemi. Something to consider.
