People think Mopar is slow??

My Dart has the grocery getter 273 (aka 2 barrel carb) so I know its slow, the best I have seen is when a self appointed Mopar expert walks up looks under the chrome air cleaner, sees the 2 barrel then tells his buddies, "oh, its just a 318". My 51 plymouth has a 318 (originally a flathead 6)was at one car show and some olds guys that have been into cars for almost ever were looking at it, I just sat back and listened, "is it a buick nail head?". "no, that's not it" "is it..." finally I walked up and they asked me what it was, told them a small bock Chrysler, "oh. now I see it, cool". Everybody thought I had a ton of money into that engine, took it to alignment shop, one guy walks in and says thats an old one and one of the employees said "you should see the engine it" told him that it was just a stock 318, he said it looks nice though. at that time it had stock valve covers and 2 barrel air cleaner, just an overhauled 318.
