Not to rain on anyone's parade but the the LS7 was an available option that was never produced because no one ordered it. The LS6 was the only one produced.

You have added over 300 cars and still remember the first of them?!

@ Super8: The first car you posted, awesome. ;)


User avatar

Super8  7y ago

The first car that I post in this site! I also remember if Viking is the first member who give a good comment in this page. After doing some long research, finally I can say.... Yes! The car top speed is 180 mph with 4 speed 3.08 final. 1 car is reportedly produced by Chevy in 1970. Some dealer then sold this engine later in 1971 as exclusive dealer installed using original body of LS5 and LS6 cars. I found 5 coupe and 3 convertible produced in 1971. All cars had side pipes and to make it looks different than other Vette, it has a rims just like animated pic that I post earlier.

I have an LS-7 crate motor in my 1971 Corvette(originally an LS5 car) Also has the M-22, al. heads,dual disc clutch, and 410 rear. Does have headers. this car is scary fast.

Since the LS6 consistently runs mid 12s .youtube.com/watch?v=MPnjVCQH0As&feature=plcp I would have to assume that the LS7 with 12.5:1 would run close to the L88s. .youtube.com/watch?v=Ufbbsu0C9jE&feature=plcp

I would like to ad to this by saying I bought a new LS7 crate motor in 1982. I (to this day) have it in a 1970 Monte Carlo. It is the iron head version and the only mods are roller tip rockers and upgraded push rods. With a turbo 400 and 4.10:1 gear ratio I had the car doing consistant low 12,s at aroung 112-117 mph. Best et was 12.03@117. The car weighs in at apprx. 4000lbs. Bullet proof motors, mine has never been apart!!

@ Super8 : No , I don't agree with you , The Weight of That Porsche is about 1.0 tone with 207 hp and The LS-7 maybe 1.5 tone with 465 gross hp or more the top speed : 155 mph and 175 mph .
There are several items , not weight only , can tell the story.

Super8  9y ago

@ Bijan : That's because Porsche was a light car. But this thing it's not too different than a big limo


User avatar

Bijan  9y ago

The horse power is not everything .
Look at the 1972 Porsche 911 Carrera RS 2.7 with 207 bhp 0-100 kph:5.7 sec, 0-200 kph : 23.0 sec ( from auto motor und sport) .


User avatar

Super8  9y ago

@ Viking : Yup that was huge for 1970 car


User avatar

Viking  9y ago

@Bijan I agree that the best 1970 Corvette that was regularly available was the LT-1. A fine revving small block indeed.


User avatar

Viking  9y ago

@Super8 your research is quite good. However, the LS7 was planned to be offered and was in the 1970 catalog, unfortunately as you correctly discovered the only one actually built was the one driven by Sports Car Graphic. The 465 horsepower is a gross rating. It was 15 hp more than the top option LS6 used in the Chevelle SS 454 of the same year. My educated guess is that it would be rated at 365 bhp net. My reasoning is that the 1971 LS6 (slightly lower compression than the 1970 version) was rated at 425 hp (gross) and 325 bhp (net). The only other engine that was close in output was the 1971 426 Hemi at 425 hp (gross) and 350 bhp (net).

@ Bijan : Yeah. Only one that ever produced by Chevy for Sport Car Graphic but LS7 later can be bought as crate engine. This car has biggest net power of all C3 Corvette since all of them is gross. This one got purely 465 Hp since the gross version got 500 Hp.


User avatar

Bijan  9y ago

In fact the LS-7 never sold to the public , it seems be a prototype.
In my opinion the LT-1 was the best performer vette in 1970, with 7300 max RPM and 370 hp, its the most powerful small Block C3.


User avatar

Super8  9y ago

I saw in some sites and say this car has SAE net 465 Hp make this car has the biggest Hp of C3 Corvette of them all cuz the SAE gross version had 500 Hp

@ Viking : Figures. I look at http://www.automobile-catalog.com/ and say the 4 Speed manual is close ratio and used for drag race. No wonder why the manual version had smaller speed than the automatic version


User avatar

Viking  9y ago

@Super8 cool link by the way. I just checked it out. I think it listed top speed of the four speed manual as 146 mph, and the three speed auto at 157 mph. I will have to look at that site a bit more. :)


User avatar

Viking  9y ago

@Super8 with tall enough gearing the estimate of 163 mph is quite possible with the Vette's small frontal area. I actually don't know how to post images. If you find out how to do it let me know, thanks.


User avatar

Super8  9y ago

@ Viking : I didn't say it's claim from GM right? Anyway in http://www.automobile-catalog.com/ Top Speed of this car is 163 mph not 180 mph but it also estimate not claim. And also i need your help. Can you show me how to post image in community comments?


User avatar

Viking  9y ago

@Super8 nice car you posted. This car was listed in the Corvette brochures back in 1970. As far as I know, the only one actually produced was the one driven by the editor of Sports Car Graphic. I can confirm that the published quarter mile was 13.8 seconds at 108 mph. Unfortunately, the estimated 180 mph top speed is a GM fantasy. This car would run out of 4th gear and hit redline at a much lower speed. I will try to find out what its rear axle ratio was so that I can give you a solid number. Otherwise, fine post!

Super8  9y ago

Err can anyone tell me how to post image on comment?


User avatar

Super8  9y ago

(automobile-catalog never post a concept car. It's mean this car is real for a while. They even had performance data) The editor of Sports Car Graphic drove it for 2500 miles and found it did the quarter mile in 13.8 sec @ 108 mph. Chevrolet also mention performance data. They said this car can reach 180 mph cuz it has optional performance 4 Speed manual transmission and does from 0-60 mph under 5 sec but that's still estimate. It also had Holley 800CFM 4-barrel carburator
That's all that i know. Tell me if i say something wrong and don't spank me OK cuz im just a kid.
