2002 ZL 1, HOW MUCH HP!
Hi, just curious regarding this,
If i understand everything right the 2002 ZL1 comes when transformed with 400 HP,!!??? But is there anybody not tuning this cars to more HP, before taking delivery?? What is done to acheive the 600 HP∆s, is it head work, new cam, etc etc?+, is there several stages on this engine package so that you like go from 400 to 450, and so on??? Thanks NEWs [img]/ubbthreads/images/icons/confused.gif[/img]

Re: 2002 ZL 1, HOW MUCH HP!
Would that mean that they stroke the engine to 427 cid, first at phase 3?
So is almost everybody buying a 02 ZL1 buying the phase 3 package, or is it a nice spread between the 3 packages? [img]/ubbthreads/images/icons/smile.gif[/img]

Re: 2002 ZL 1, HOW MUCH HP!
It is about 1/3 Phase 1
1/3 Phase 2 1/3 Phase 3 It is funny but that is just the way the #'s fell. There was not a real plan, it was just the way it turned out.

Re: 2002 ZL 1, HOW MUCH HP!
NEW - I believe all the 427s from GMMG will have C5R blocks. As far as the stages go the numbers may be misleading. For example, I chose to take delivery of mine as a stage I but am in the process of having a C5R 427 built with the new 090 casting C5R heads. I am also going with some other after market parts such as a new clutch and rear end.

Stefano - Lamar likes the Strange rear end, McLeod dual disk and Hotchkis parts.

Re: 2002 ZL 1, HOW MUCH HP!
A little Bird told me that the C5R 427s for the Camaro Super Car ZL1s have actually Dynoed at 625 flywheel hp and are getting over 500hp to the rear wheels. I would think that a stronger rear end would be a necessity?

Re: 2002 ZL 1, HOW MUCH HP!
I agree. I would think that the rear end or clutch would be eary casualties. Lamar or his son are going to take mine down the track for some magazine articles and ESPN II. For the shoot they are going to install some drag radials. I don't want to waste a day watching parts fly all over the place. [img]/ubbthreads/images/icons/blush.gif[/img]
