Mark, a couple more thoughts. Is this a stock cam or an upgraded cam? If
upgraded, did the shop have the specs to degree it in too? If not he would
have probably used the factory timing marks and the settings might not be
the same as the replacement cam. Another thought is your camshaft is shot,
as a couple of the cam lobes are worn down. This would have nothing to do
with the repair but would have been gradual.

In the words of Philip Fry, "Oh Crud!"
You can imagine I will have to do some testing, but I can only hope that
they
just slapped on the chain and didn't adjust the timing. That would put
things
way off without requiring me to tear apart the front end (or face another
warranty battle). It could well be you're all right since the low end torque
seems to be quite poor off the start whereas before the fix she had a very
good pull. Now to hope that it's adjustment, not wrong tooth/chain
placement.

I vote with Randall. It sounds like the cam timing is a tooth or so
different than what it was before.
