<t>My car does not say anything on the paperwork about phase IX but it doesn't say its a phase I . GMMG paper work just says 3.73 gears and 13/4 headers does not mention any phase and it sure seams too have a lot more power than 380. But that being said If mike can confirm these cars are really phas...

its the second phase down it says Phase 1X 425HP (370 RWHP) All of the phase 1 stuff PLUS Dynatech 1 3/4" Long Tube Headers it list phase I then phase IX then phase II

<t>In the posting right above this one Mike has the phase IX listed he says all the goody's the phase I has plus 1''3/4 headers 425 hp rwhp 370 ?????????? Mike Carnahan was kind enough to take some of his time and explain in detail the phases to us:<br/> <br/> Mike@Vengeancepcm wrote:<br/> <br/> Guy...

57,000 easy miles. car is in perfect shape has slp headers BBK throttle body and a stage 2 power chip have all the original docs and window sticker. Car has had one repaint these cars where famous for the clear coat peeling. Fun car to drive one of my favorites.

New addition to the garage a 1990 IROC-Z super clean low miles 5.7 last of the irocs

Does anybody have or know were I can get a Berger prescribed power key fob?

I wonder what kind of money it might have brought if it would of had super low miles.

Looks great

Is their any update on the GMMG badges? Thank you.

Nice pics. I feel bad for all you cold weather birds if you lived in a place like Arizona you could enjoy all year around.
