@ Kctransplant: You're absolutely right, most old school muscle cars were geared for acceleration rather than speed, that's not saying they weren't fast for their day, though.

Assuming 25 ft^2 area and .5 CD I get 827 lbf drag at 161 mph. This translates to 416 hp from the engine with 85% efficiency.

Interesting to see this is that 416 without drive line losses? If that's the case then it would never happen cause when the ls6is built to pure stock specs they average 490at the flywheel and lose around twenty percent through the driveline

What many people fail to realize is most big block muscle cars had their top speeds limited by gearing rather than drag. With the right gear ratio an LS6 EASILY made enough power to top out at 160 MPH. But like I said, it depends on the gear. 4.10's would top out somewhere between 120-130 because they would hit the redline there, but a 3.31 rear gear allowed the car to go much faster before hitting it's redline, given acceleration was a lot more violent with a 4.10 geared car.

Are you sure that top speed is correct?, 161 MPH?, Really?

I dunno about the other country but it looks like someone exports it into Japan. Cuz when my father bought it, the previous owner doesn't know how it can reach Japan. He said he just bought it from other people. The one that my father bought is the CRV transmission code. Just like this one

Because the LS6 in 1970 was so powerful, it still reach 13.7 for 1/4 mile. The 0-60 mph time is reduced to 6.1 from 5.3 from 3.90 ratio. The greatest thing in this car is it's top speed which can reach 160 mph while 4.1 and 3.90 ratio could only reach 130 and 140 mph. The transmission code for this car is CRV.

This is probably the second rarest Chevelle SS after convertible version. A lot of Chevelle SS using Muncie M22 with 4.1 final ratio as standard transmission and 3.90 ratio as optional. However you can order order one Muncie M20 3.31 final under COPO just like Monte Carlo. It's the rarest one because not many people order it. Some of them also fitted with aluminum head which will reduce weight a lot. This data i got from my father book. It contain factory specs of this car even performance data.
