Re: the Navarro Six

One more thing -- looking around on Barney's site, I found that not only does the Rambler have a flat-head Ford V-8, but it was a class record holder at Bonneville!!
I have to admit, I've thought about putting a flat-head Ford V-8 in a 61-63 American. The engine is narrow enough to go in without modifying the body, and a flat-head just "feels" right for the 58-63 American -- both are "dated" looking. If I could have got one easy about 10 years ago I might have thought harder about it. A friend of my dad's used to race a flat-head Ford on circle tracks up through the early 70s. He consistenly placed in the top 3-4 running against bigger SBCs. If he'd had a core engine on hand I'd probably still have my 63 American... with a flat-head Ford under the hood!
