It really depends on the rear end (final drive) ratio. With steeper gears like 4.20's, it is redline limited. With a tall gear like 2.56's it would most likely be drag limited, given, they rarely, if ever came from the factory with a taller gear than 3.31:1.... Especially if the car was equipped with a 4-speed.
The Chevelle... Especially if it has a solid lifter engine like the L78 396 or the LS6 454.
Oh yes!!! There were two engine options for the 1970 Chevelle SS454. The LS5 was a mild, hydraulic lifter engine rated at 360 HP. The LS6 was a solid lifter fire breather rated at 450 HP.
The Chevelle was built from 1964 to 1977. After 1977 the Chevelle name was dropped and all "Chevelles" were called Malibus after that. The most popular year for the Chevelle is 1970 thanks to the LS6 engine option. the LS6 is a 454 CID V8 rated (grossly under rated) at 450 HP, and it was the highest rated factory installed, regular production ever built at the time. It held that record for decades. 1970 is the ONLY year the LS6 engine was available, and the Chevelle was the ONLY model it was ever installed in.
The 70 LS6 Chevelle with the 454 big block was rated at 450 horse power but at the dragstrip, with only mods to prevent body tweaking, it put out closer to 480 HP.
Buick GSX 455, Pontiac GTO 455, Chevy Chevelle LS6 454, Dodge Charger 440 or 426, Ford Mustang 428, Dodge road runner, challenger 440 or 426.
A 1971 Chevelle was available with every engine in the Chevrolet line-up from the LS6 454 to the 250 cid inline six. With that in mind, the mileage would be somewhere between 4 mpg and about 25 mpg.
With the factory LS6, or 7, in the 10's, right off the showroom floor. I knew a guy that had one.
you could get the 454 but I don't remember the LS-6 being offered in the monte.
The standard ratio was 3.31:1. It really depended on whether the car was equipped with an LS5 or LS6, and which transmission was ordered. Basically, ANY ratio was optional from 2.73:1 through 4.56:1 with the turbo 400. You will probably never see anything numerically lower than a 3.31:1 ratio with a close ratio 4-speed, and the ONLY 4 speed available for the LS6 was the Muncie M22, which was ALWAYS close ratio. 3.73:1 and 4.10:1 were the most common for the LS6.
LS6 Chevelles had rear disc-brakes
Which 454? The LS5 and LS6 are two VERY different engines even though they are both 454's. Timing specs are different as well. 8 degrees before TDC at idle will work for either, but may not be optimal.
I want to say that it was around $4,500 dollars give or take. My dads Chevelle Convertible came to a total of $3,397 when it came off the production line so with it being a Super Sport and an LS6 car which they only made around 980 of. Hope that helps a little.
