Hey, quick question: I have a guy coming in today for a tune up. It's a 55 Stude with a Chev 350. (long story) He's a great guy but confesses he does not know much about the engine... as in what it came out of. Thinks it's 70's HEI ignition with Rams Horn manifolds. I'm thinking mid/late 70's pickup? The reason I ask, I have run into this before and had a hard time getting plug wires that clear the exhaust. ANy ideas so I don't have to "Make up" a set like last time?
