Firehawk came home

[t5irocz]

Absolutely incredible car!!!!! So glad you were able to get her out of storage. We chatted about your car via PMs a while back, it's gorgeous!!!!!!! Thanks so much for posting the pictures!! It's honestly an all-time dream car for me. As I mentioned before, if for any reason you end up deciding to sell it at some point in the future, please keep me in mind.

I got my 87 IROC out for it's last ride of the season, a fall foliage trip last week. I broke 11k original miles on it, loved each tick of the odometer

Lost track of my 92 1LE at about 150k miles. Sold it to a friend who sold it to a cousin in Hollywood somewhere. last regged in 2005...crashed? parted out? Everybody who owned it drove the hell out of it. It got rebuilt with forged pistons and had a vortec supercharger with 3.73's.

Notice the fog lamp delete: that's a 1LE Z28 tell-tale:




I remember sh!#t!ng bricks at the $290 monthly I had on it, haha.

Neat car! The heritage 1LEs are unusual. was yous a 5.0 5-speed or 350/auto?

There is one in the GM heritage center, white with red stripes I believe. I have a line on a low mileage one that i'm hoping to see in the next week or so. Really want to get another low-mile f-body.

It was the 305 on the 5 speed manual. Which turned out to be a good choice later on for unexpected reasons. I ordered it with the heritage appearance pkg, the 1LE and the required group of stuff with that, body side moldings, power hatch release, power windows, and the deluxe interior. All the group convenience packages were bundled with a/c so the only way to get anything was ala-carte. it cost more though...I think the base car was about $14.5-$15k and optioned up was $17-ish (invoice).

The MY 92 Z28 came with the optional T5 ratios- it was always so much quicker than my friends 89 iroc with the tall overdrive ratio. I do not know if it was strictly a 1le thing or if the last couple of years of f-body had the revised ratios on the 5 spd option. the rpo code was different. When the car got supercharged, the parts matched very well since peak efficiency of the blower came it at peak torque accentuating the TPI powerband perfectly. It would roll with an early viper on the freeway. Didn't hurt that it only weighed about 3280 lbs if I recall correctly.

Very nice!!

Wow, the ZR-1 and the Firehawk together are beautiful. Very nice stable!


I was going to post a pic of my Z and my Pontiac (Grand Prix GXP), but after seeing your Z and Pontiac ... not to mention the other cool rides in this thread ... I'll pass

there were a couple 305 engines in 89, 1 with the "good" cam and one with the crappy cam, If the 89 Iroc had the G92 option with dual ca6t on the 305. This would make the 305 have 230hp/300 lb/ft torque with 3.45 rear gears, while the other TPI non G92 car would be 220hp/290 lb/ft with the 3.08 rear gear.
Then the autos got the crappy cam and 195hp/295lb/ft engine with the 2.73 rearend. Blah.

The only way to get a ILE car with A/C was to order the B4C cop car option. Straight 1LE cars necessitated rpo C41 (a/c delete).
Sounds like your 92 was a dual cat car with 230hp/300lb/ft torque and if its a manual trans it got 3.42's to begin with. More power, much better gearing than the 1989 Iroc your friend had.
I cant find anything about an IROCZ manul trans that had special trans gearing.??

I always liked the 85 IROZ, it came with the best of the 16x8" rims, Iroc decals(IMO) and the 85 IROC-Z package was a full load, not segmented like it was in later years.
My buddy has a 1990 IROCZ auto with 15"rims and a drum brake rear end, very poor optioning.

IROCZ's had decent 0.34 cd's and pulled off 0.90g cornering. Unoptioned 87 IROCZ's weighed 3250lbs with a 305/manual trans combo.
Formula 305 5.0 5-Speed 3383lbs
IROC-Z 350 5.7 Automatic Overdrive 3341 lbs
GTA 350 5.7 Automatic Overdrive 3476lbs
Formula 305 5.0 5-Speed3,383
Formula 305 5.0 5-Speed3,383
Formula 305 5.0 5-Speed3,383

Too bad they didnt run the 1992 Collecter Edition with the ZF6 six sppeed and 270hp TPI engine.
That one off LT5 powered F-body is cool.
