Yes, and no.  I'm using the same coils as those on my 2000 Chevy P/U.  It has
the small LS1 v-8, I think it is a 5.3.  Anyway, it has eight individual coils
mounted on the valve covers.  The connector is on the opposite end as the
secondary lead tower.  It takes a different connector as the Corvette coil, so
make sure you get the right ones.  As I recall, I had to make a minor mod to
the connectors to get them to fit, but you would never know it by looking.  

The GM p/n for the connector is 12126487 or PT757 (A/C Delco).  The GM p/n for
the coil is 12558693, or D581 for the Delco p/n. As for cost, I don't think
they were any cheaper than the Corvette counterparts, but I didn't compare
prices when ordering.  Coils were about $27/ea and the connectors were about
$30/ea.  Might be cheaper to buy a complete harness from GM.

Coil wires were another problem.  I got the coil connectors from MSD (call them
and they will send a set for free) and then cut up a set of universal plug
wires.
