Why list it for a $1 and have an asking price of $8500 
For those who don't know what the original ZR1 or LT5 is...
ZR-1 (1990–1995)
Chevrolet Corvette ZR-1
In 1986, the Corvette team approached Lotus, then a GM subsidiary, with the idea of developing an ultra-high performance vehicle based on the C4 Corvette. With input from GM's "Corvette Team" of engineers and designers, Lotus designed a new engine to replace the traditional pushrod L98 V-8 that powered the standard C4. The result was the LT5, an aluminum-block V-8 with the same bore centers as the L98, but with four overhead camshafts and 32 valves. Lotus designed a unique air management system for the engine to provide a wider power band by shutting off 8 of the 16 intake runners and fuel injectors when the engine was at part-throttle, while still giving the ZR-1 375 hp when at wide open throttle. As Chevrolet had no facility available which could manufacture the new LT5, construction of the engines was subcontracted to Mercury Marine, a company in Stillwater, Oklahoma which normally specialized in high-performance marine engines.
Lotus also aided in the development of the ZR-1's standard "FX3" active suspension system, which would provide the basis for active suspension systems found (as optional equipment) on all Corvettes since. Much of the ZR-1 tuning was done at Belding, Michigan's "Grattan" raceway.
In 1990, the ZR-1 set a 24 hour speed endurance record at the Firestone test track in Fort Stockton Texas using a near-stock LT5 engine with only minor modifications, including removal of the catalytic converters. The Tommy Morrison racing team averaged 175 mph (282 km/h), including time for re-fueling and several driver changes.
In 1991, all Corvettes received updates to body work, interior, and wheels. The convex rear fascia that set the 1990 ZR-1 apart from the base model was now included on L98 Corvettes, making the styling of the expensive ZR-1 even closer to that of the base cars. The most obvious difference remaining between the base and ZR-1 models besides the wider rear wheels was the location of the CHMSL (center high mounted stop lamp), which was integrated into the new rear fascia used on the base model, but remained at the top of the rear-hatch on the ZR-1's. All corvette ZR-1's had a interesting feature, a power key. It was mounted underneath the radio and using a key you could turn the power from "full" which means all the horsepower and "normal" which disabled the secondary intake ports cutting the power to 200 hp (150 kW). This system is commonly referred to as a "valet key", and was reset to "normal" after the engine was shut off.
Further changes were made in 1992: ZR-1 badges were displayed on both front fenders and traction control was added as a standard feature. In 1993, Lotus redesigned the cylinder heads and valve-train of the LT5, resulting in a horsepower increase from 375 to 405. In addition, a new exhaust gas recirculation system improved emissions control. Production of the ZR-1 ended in 1995, after 6,939 cars had been built.

Alright cool I was wondering of the existance not the ad, sorry should have been specific, and thanks for the detailed response I had heard a little about the dohc motor for the zr1 but people always refered to the lt4. Thanks again for the information I like to be informed on useless facts.

LT4
The LT4 was a special high-performance version of the new-generation LT1. With the addition of a slightly more aggressive camshaft profile, 1.6:1 roller aluminum rocker arms and better-flowing intake manifold (painted red) and cylinder heads, it was rated at 330 horsepower (250 kW) and 340 lb·ft (461 N·m). It was introduced in the 1996 model year, for the last year of the C4 Corvette, and came standard on all manual transmission (ZF 6-speed equipped) C4 Corvettes. The engine was passed down to special versions of the Camaro and Firebird the next model year.
The LT4 was available on the following vehicles:
* 1996 Chevrolet Corvette when equipped with 6-speed manual transmission (includes all Grand Sports) (Production: 6,359)
* 1997 Chevrolet Camaro SLP/LT4 SS 6-speed (Production: 100 for the U.S., 6 for Canada. There were 2 prototypes)
* 1997 Pontiac Firebird SLP/LT4 Firehawk 6-speed (Production: 29)
But I thought that the LT4 made it's way into some '96 SS Camaro's as well.
