would our trucks be considered muscle trucks?

[74chevy454]

My truck was bought by my grandfather back in 9/73 thats what the date is on the door jam info it was the top shelf model came with everything there was out for that year that came in a truck 454 th400, 3.73 14bolt, no smog, the good 781 heads and all the nice trimming. It was the towing package with 15x10 rims. Cheyenne super custom deluxe I think thats what the badgeing said. I have owned it since 92 when he sold the cement business. I ran the stock motor till the main beaings went bad. Took that stock 454 and put it in the corner for rebuild and through in the 468 all edelbrock components motor I built. I think if it came with low suspension and bb from factory that it could be called muscle. But mine being the 74 it is not considered a classic but california says its smog exempt so I say its a classic to me but its each ones opinion on the subject.
