1995 PRODUCTION DATA
- The last year of ZR-1 production, 448 produced
- #418 was 1 of 16 DRM's of which it was 1 of 6 with black interior and 1 of 2 (#418 & #179) with the "blue glass" dual roof option but,
#418 remains unique as the only car with a matched set of A. L. Dunn heads, #418 was also the last DRM made
- Late production cars (~the last 100 cars) received A. L. Dunn heads. These heads included "state of the art" high flow head & runner work, machining, porting and polishing.
#418 has a pair of Dunn heads, most cars received a combination of a Birmal (early production heads) and a Dunn or a set of Birmal heads. The Dunn heads were originally slated for
the '96 ~425hp cars but production stopped
- The ZF S6-40 6 speed is specific for the ZR-1, the difference is a longer input shaft and guide tube unlike those of L98s, LT1s or LT4s. The gear ratios are: 2.68/ 1.80/ 1.31/ 1.00/ 0.75/ 0.50 and reverse 2.50. The 540 Nm ZF
has increased helical pitch of all drive gear teeth to provide a more quiet mesh over earlier years. The 2nd/ 3rd/ 5th/ 6th gears went to a crimped spline-fit method of fastening the synchronizer clutch body to those speed gears.
The reverse lockout was replaced with a "high-detente" design
- The LT5 powerplant is a Lotus designed (in England), Mercury Marine built all aluminum engine. Designed with a "pent roof" combustion chamber it is a 4 cam
(dual overhead cams X 2), 32 valve (4/ cylinder), 350 cu. in. V8, sporting 16 fuel injectors. There is an ignition key and a second "power" key which toggles 8 of
the secondary injectors on/ off
- The LT5 was detuned to only 405hp @ 5800rpm & 385 ft. lbs torque @ 4800rpm, Redline @ 7200rpm
- 405hp LT5 highlights: Revised back angles of the valves, Multi-angled inlet & exhaust seats, Head work to increase flow, Revised exhaust cam timing, Revised injector housings & injectors,
Altered plenum for increased flow, Smog changes, Reduced rotating mass of all major components, 4 bolt cylinder case, Valve retainers, Revised prom, and oil system improvements

ZR-1 "KING OF THE HILL"
ZR-1's were produced from 1990 to 1995. General Motors built a total of 6,939 during the 6 year run. The first year 1990, GM built 3,049 ZR-1's, in 1991 they built 2,044,
in 1992 502, and from 1993 to 1995 448 cars were built each year. The 1990 - 1992 ZR-1's were rated at 375hp, the 1993 - 1995's were rated at 405hp. The '95 was the most option-laden, highest net horsepower of any Corvette ever built. The cars hold fanfare to this day
as witness to the after market autoparts, endorsements, models, posters, books, clothing, jewelry, and games etc. New ZR-1 items constantly appear on the market today, 17 years after its world records.
The option, RPOZR1, with dual removable roof panels was $32,208 above the base sticker price, the ZR-1 totaled for $69,553 in 1995.
There were $150,000 race cars which could not compete performance wise or in price. The '95 was the most refined of the ZR-1's, the potential for future
appreciation is high due to the low production numbers, higher horsepower, and last year of production, its legendary history assures its collectability and appreciation
in the years to come.
On the average, a stock ZR-1 will do 1/4 mile times around 12.9 sec @ 100mph and 0-60 in 4.9 seconds. On March 1st & 2nd, 1990, Tommy Morrison set 3 WORLD and 12 INTERNATIONAL speed records with a
right-off-the assembly line ZR-1 at a test track in Fort Stockton, Texas. With this record run these drivers made their mark in the history of motor sports; John Heinricy, Scott Lagasse, Jim Minneker, Don Knowles, Stuart Hayner, Scott Allman, Kim Baker. and team owner Tommy Morrison.
To this day the 24 hour endurance record still holds at an average speed of 175.885mph for a production car. This is comparable to 10 back-to-back Indianapolis 500's. With speeds in excess of 180mph
the nickname "King of the Hill" was forever burned into the annals of motor sports.
