Just lookn for some info/history on McGurk 6x2 manifolds for small block chevys. Everytime I ask someone there eyes get all big but have nothing informative to tell me. How rare are these things? Anything neat about these things besides bein a 6x2? Just interested in a little more knowledge. Thanx in Advance.
How rare are they? In the past 25 years of hunting parts at swap meets, I've seen three. My 1962 "Modifying the Chevy V8" manual has a picture of one in it.
