Why is it only 1955 - 1975? If you can't include modern you shouldn't include prior '60 or after '74. The '87 Buick GNX's were monster muscle cars in any era.
I wanted to see how many of you had real Muscle cars(i.e. the big money cars, 426 Hemi's, 427's, 454's, 400's, 455's Olds, Buick's and Pontiac's, 428 and 429's and 390, 401 AMC's and small blocks too, so on)
Many muscle cars where made from 1955-1975, Chrysler started it with the 300's Hemi's in 1955, and it ended with BOP's(Buick,Olds, and Pontiac) in 1975.
Side note the first real "muscle cars" where built in the 1930's, DUESENBERG had 270hp in 1930 with the inline supercharged 8(it would do 102mph in 2nd gear!!), and that was when V8 Fords, and Chevy's only had a max hp of 60.
If you want to talk about New muscle cars, thats fine.
