The Gremlin they list as a "muscle car" is a 1978. By no means muscle. What beat your 396, well that car was prepped with an after market engine etc.. Read ab7fh post above.
As you wish.
My reply was to Mopar410's questioning if anyone thought a Gremlin was a "musclecar". I do. Was it a 78? Don't know, don't care. I couldn't tell you the difference between the years of them odd looking little dudes. I can say I lost a race to one. I can say the owner said it was a 401. I can say it looked like it came with the car. I can also say I can't tell you the difference between a 304, 360 or a 401 without crawling under the car and looking at the casting on the block. (I believe it actually says engine size for retards like me and you).
So at the end of the day, what difference does it make? What's your point? Whatever makes you feel better, I'll agree to it. Let's go with it was actually a 304 and the dude was just being nice and telling me it was a 401 so I would feel better. Does that make your world level again?
