This is the part I like, where, after a good basic question (there are no dumb questions) we get some good basic answers that cover the topic. Then the experts jump in, and no I don't know the difference between a 350 and a 361 MOPAR. Wouldn't know if it jumped up and bit me on the . . . well, you know.
My room mate in college had a '59 Dodge convertible with a big v-8 in it. Don't have a clue what it was. We did put a whole new exhaust on it though, used the flex pipe stuff. Worked really well bending all around everything.
