Searching for a Mopar Mechanic near Chicago"

I'm no expert but lots of changes. Isn't that cam a little long on duration? Cam timing is important. Did the 73 340 have 2.02 valves? Asking for myself as well. Stock 73 340 is a low compression engine. Stock 73 340 didn't have a square bore carb did it?

A friend of mine bought a new 73 Dart 340 Sport manual trans. He put a lumpy cam in it soon after he got it and it sounded good, but it felt weaker than stock.
