It doesn't happen every day, but sometimes you just fall into something really, really good. That's how it was with me when I was researching an upcoming article on pre-muscle speed parts and my friend Kevin Carlson told me about the existence of an exceedingly scarce original Roof overhead-valve conversion for Ford Model A's. And it's what happened to Brandon Fish of South Kingstown, Rhode Island, when he answered a Worcester, Massachusetts, classified ad for a couple of Winfield SR carburetors, a homemade intake and what turned out to be that rare Roof OHV.

"I drove up, and it was a blizzard," Brandon remembers. "It took me two and a half hours to go maybe 70 miles."

Look back on this fleet-of-foot Model A from 1930.
