Again, this was the only aluminum block version of the L88 race engine offered in 3 production cars. If you educate yourself before squawking you will find the engines were underrated for production and obviously not race prepped with slicks, ect. The cars that were race prepped set the Mulsanne GT record of 215 mph. These cars are auctioned with a long history, some worth over 1 mil. Fastestlaps has a 1970 LS7 that was never produced, again another race engine available in crate only, ie. race fuel only due to the high compression ratio.

Top Speed 215 mph. This was a race car direct from the factory, 103 octane requirement and racing slick requirement. Only 3 produced.

Top Speed 215 mph
Not on planet Earth with the thick atmosphere we have over here. You need close to 500 hp to exceed 200 mph. And 215 is a lot more than 200 - power demand goes up parabolically for each mph extra.
And at 215 stability becomes issue, tyres become issue, gearing becomes issue.

Cars didn't come with true racing slicks back then. They were all bias-ply tires whether it was racecars or roadcars. The top speed would have been WORSE on the modern-day slick tires.

According to Bob Bondurant the ZL1 Corvette could reach 172 mph on the Mulsanne straight at Le Mans. That was its top speed.

@fastestlaps please delete the Super8 performance, except of the 1/4 mile, at these two pages and combind them:

Please change the power to 430 Hp

Anything I have ever read on the 1969 Corvette or Camaro with the ZL one option had an all aluminum head and block for 427 560 horse if you deduct the 15% loss in horsepower at the rear wheels You’ll be closer to 500 hp in near 600 foot pounds of torque.

I update the old data because a lot of data from this monster is wrong. This monster had all aluminum block make this engine into a lightest GM Big Block. Because the option is so expensive, Chevy decide to make it just two. One with Daytona Yellow and one with Can-am White. The torque is unknown until now. The biggest mystery on this car is the net Hp. From the trusted source Camaro ZL1 only had 376 Net HP but in this Corvette you got bigger compression ratio than Camaro ZL1 (Camaro got 12:1 but Corvette got 12.5:1). So, it might be Corvette got more net Hp and probably near 400 net Hp. Top Speed also the biggest question. From some source i read, The Daytona Yellow Paint Job got Muncie M22 close ratio while the Can Am white got Muncie M20 long ratio. It can accelerate from 0-60 mph in 3.9 sec and 0-100 km/h in 4.3 sec for close ratio. Top speed for long ratio maybe near 190 mph or more but below 200 mph due aerodynamic problem (it has 0.4 cd) beause it got more power than L88 and more lighter than any Big Block Corvettes.
