OK, 9's and 10's are being optimistic (I was prolly thinking 0-60 times) but, muscle cars off the showroom floor could run 13's. Do the right upgrades and you could hit 11-12's if you cut a good light even without being a pro.
The point is there is something about raw horsepower and torque of a 60's muscle car that is incredible.

Cutting a good light can determine the winner but it has nothing to do with the e.t..

You check the right boxes at dealership and put on a set of slicks, you would be running fast enough that now they would make you leave and not come back until you put a roll cage in it.

Mr Norm if you were a Mopar guy or Don Yenko if you were a Chevy guy, they would hook you up with something special. Big block Dart is going to blow your hair back a little, 500 ft/lb and 4.10 gears in a little car like that, it would leave with alacrity.

There was a guy in Sacramento about 50 years ago that had yellow bug that ran low 11's had little clip on wheelie bars and put them to use. Street driven, son of a guy with a VW speed shop, pretty car, yellow with a lot of pearl in it.

Not as rare as the ZL1 shown above, Chevy also made about a thousand of these L72's that had an iron block 427.

4:10 LS axle standard, 4:56 available, with three transmissions offered, a close or wide ratio 'rock crusher' or a Turbo Hydra-Matic.

Yep, I had a buddy in HS whose dad had given him a '70 el camino with the 402.

My dad had a buddy that had a '67 427/435 corvette. According to my dad it could get into the 11s-12s with a little tweaking and good driving.

This is an interesting article about Baldwin Motion

Minor correction. Only the M22 was called the "Rock Crusher" and that only came in close ratio. I had a car with the M21 which was a close ratio but with differently cut gears (helical, quieter than the straight cut, loud M22). Per the tidbit below, I guess I had an M21.

Per https://www.motortrend.com/how-to/muncie-m22-transmission-rebuild/

"the Muncie came in three basic flavors: the wide-ratio M20, the close-ratio M21, and the heavy-duty M22 close-ratio transmission."

11 second range for a true street car of the 60s trough the 80s was a challenge. 10 second range was about the fastest, and 9 second was a pure drag car.

Watch Roadkill or Roadkill Garage and watch how hard they work to get a 10 second car it makes it clear. They use basic stripped cars with little interior parts, and sticky drag tires and even with nitrous and superchargers 10 seconds is hard.

And once you get to the 500HP range for engines or above the price skyrockets fast for the best heads, cranks, pistons, rods and engine blocks.

I stopped to get beer recently, and this guy pulled up next to me. It's a 67 SS396 but the 396 is long gone, and it now has a 454. He said is will spin tires at 60 if he floors it. He still is in the high 11s with a car he and his dad spent a lot of money on with a built transmission and 9 inch rear end.

I never knew that about the "rock crusher' - good information. :)

My Chevelle had the Rock Crusher M22 - also a must:
the 12 bolt posi instead of 10 bolt
scatter shield for the 20 (?) steel flywheel
extra high torque starter
Accel super coil, wires, and special plugs to handle the spark

For fun:
Surfer foot pedal, cassette deck with 20 watts per channel amp !

I had a shop back in the late 80's next to a body shop that ended up painting cars for Foose and the TV show. Great place because all the shops were behind a fence locked at night.

The body guy was building a bracket car that he said was targeted at the 10 second mark. As such, it was stripped to the shell and all seams were continuously welded over the spot welds. And at 10 seconds a full cage was required.

So, yeah, it takes a lot of work and money to go 10 seconds and keep the car together week after week.
