This is the real view of muscle cars.
Muscle cars is the ones made from 196x to 1973 and came with the big engines.
Why 1973? because that year the 440 disapeared, the 426Hemi no longer existed, no more 318, no more 429, no more 428, no more boss engines, no more Mustang Boss, no more any fun car!
At 1974 noone wanted the cars with big muscles etc.
The big oil crisis started then and everyone wanted small crap cars.
1971 was the last year for Mustangs Boss version.
1973 was the last year for the big engines.
Then 1974 came the Mustang II, the small ****ed up Dodge Charger which noone knows about, no more Challenger, no more Barracuda etc.
AMC Pacer, Mustang II, Ford Pinto etc. The list can be long of what people wanted.
They wanted small 4-6 cylinder engines.
Then in 1993 (I think) Ford's legendary 5.0L v8 disapeared instead they use 4.6L.
They brought the 5.0 back on some cars, but can't remember which ...
