Is there a nice chart/breakdown of the differences between 97-04's?

I've done some searching around the forum, with not much for luck.

I specifically looking for info on coupes, but convertible or Z06 data could be nice too.

Any recommendations are welcome too...I've been looking at coupes with the dual roof option and Z-51 packages so far.

Sorry if this is a repost or a n00b question, but thanks in advance!

BTW - I found this using the search feature.....

 

I'm a newbee, N00b, etc. too. I think it's been asked but ya never know until you ask. And hopefully it will be a gentle response without any put downs. Besides, I want to know too.......Finish your profile........

 

You're fast blacksedan87!

 

Can you imagine that I typed all of that?

 

Her is a great website: http://www.corvetteactioncenter.com/specs/index.html

 

Hey Randy, I thought you weren't going to help out on these threads anymore let alone type all that You must of been the top of your class at Mavis Beacon Univ. Glad to see you back in full force helping out a bro

 

I took a vacation from work and the forum, and came back with a new attitude. It's all good my friend!

 

Correcting a couple of discrepancies. Don't know about other years.

2000
* Millennium Yellow available
* "Thin Spoke" versus "wagon wheel" design wheels become standard.
* Pup cats added to all models for LEV emissions requirements (5hp loss relative to 97-99)2000 Corvette LEV-compliant in states requiring California emissions. Different cam in 2000 engine, I believe compensated for the 5hp loss.
* Steel swaybar endlinks instead of plastic on Z51 equipped cars Rears were still plastic
* Z51 swaybar diameters grow (25.4/21.7 to 28.6/21.7 to 28.6/23.6 (note: new rear same as Z06)
* No keyhole on passenger side doorhandle
* Passenger airbag 'off' switch added to console (light by TC/AH button) Added late model year

 

Yep, so the 2000 vettes delivered to non LEV states, like mine, actually had 350 hp, since they still got the bigger camshaft (.500 lift) but did not have the pup cats installed.

 

You forgot - 2000 - Dark Bowling Green Metallic available!

 

well thanks for the info guys! I went out and bought a GM certified torch red 2004 coupe with 16K. I think I'm hooked!

 

Congrats on your buy and where are the pictures
