There is nothing wrong with it.
Here is the way things have progress over the decades and at the bottom how it has and will effect all of us in the future.
40s: After WWII when GIs came home there were really no cars that spoke to the youth until into the mid 50s so guys were taking cars from the 20s-30s and chopping them up, adding what custom speed equipment that was available or they could manufacture themselves (thus the birth of custom speed equipment companies) etc. Then with the birth of more V8s in the large cars such as Cads. & Lins. the hot rodders had power plants avaialble and these cars got faster. Now custom paint, flames, etc. came on the scene.
50s: When car mans. finally started to make some decent looking cars with some style in the mid 50s and GM gave birth to the light weight V8 in the form of the 265 CID engine (that is still with us in up to 400 CID) The WWII and younger buyer began abandoning their hot rodding days and started the customizing craze. Lowering cars, lake pipes, custom paint and interiors because they had cars with a decent power plant from the factory. Still the custom equipment companies grew primarily for the race crowd which was mainly street racers.
60s: Saw the move to sanctioned off road racing in the form of drag strips, added interest in stock car racing, and sports car racing. The manufacturers slowly recognized the youth market as a considerable buying market and the muscle car was truley born in the mid 60s along with the pony cars. Still the after market mans. continued to grow.
70s: With the decline of muscle cars due to high insurance, poor fuel available, high priced fuel, etc. both the truck and van craze began with the van getting the larger share for a short window of time.
80s & 90s: The smog years and more of style in the form of stripes, spoilers, flairs etc. IROCs, Firebirds, HO Mustangs, Shelby Chargers, etc. Some with still the ability to perform like the core vehicles of the original muscle cars.
The new century: This saw the NEW muscle cars mid decade to present with the Mustangs, Challengers and Camaros.
Now, with all of this said NONE of these core groups have ever died out. The hot rodders, customizers, muscle car, vanners and of course truck people etc. are all still with us. Some in the form of old gezzers, some with new younger blood in all of these groups. The vast majority have maintained their core loyalty to their group but the NEW YOUNGER muscle car guys have deviated to some degree with the resto-mod craze that is not too far removed from the hot rooders with the exception that they want to maintain the original outward appearance with the new technology of current drivetrains for both power and economy.
HOWEVER, I certainly don't see anywhere CLOSE to the above stated 65%. Time will tell what lies ahead. History has always shown us that things are cyclical and most things return to their core roots. Most people are loyal to their vehicle manufacturers and the drive trains they came with. The Chevy engines have always been popular with hot rodders because of availability and the lower cost. I think what we are seeing today with some of these GM engines in Mopars is the same thing, more economical in these tight times but I doubt that it will last and then those that did it will find out what the REALLY saved (or didn't) when things swing back around and they want to sell.
