These are the differences between the z06s.

From '01 to '02 --> revised intake, slightly different cam, piston ring fix (oil consumption issue), HUD standard equipment -upgraded to 405hp from 385

From '02 to '03 --> control arm bushing upgrade (problem with slipping control arms on '01s and '02s), Bilstein shocks as standard equipment, fuel pump relocation

From '03 to '04 --> valve spring upgrade, stiffer Sachs shocks, further bushing upgrades, different t-stat housing

 

OnesweetZ06's vette is sick...and very very fast...nuff' said

 

Have a Corvette coupe, that is identical looking to a Z06

 

I have an 04 z06.


the 02's have a different cam than 03-04. 04's had revised shocks.

 

The 01s had a different cam -- the 02,03, and 04 cams were/are the same.

See my post above for all changes made during the z06 C5 run
