I know I am stepping into this flathead thing big time since I was the first to reply to the Bio-Diesel flathead post but all these engines were an ancient design. Ford was the most popular because they were the only cheap V8 in the 30's to mid 50's that hot rodder's and racers could buy cheap and the speed equipment business grew from them. In the late 40's when GM came out with the Olds and Caddy OHV V8's the flathead what ever engine's were dead. Straight 6's, straight 8's and the Ford V8 flattie. Pontiac had a similar looking Corvette style concept car with a straight 8 flathead Pontiac engine in it in 52-53?. For all you gray beards here you will know what a Studealac or Fordalac conversion is from Honest Charlie himself, for you kids read closely the words. The 265 V8 Chevy engine bridged the time from flathead to the modern cheap OHV engine and has stood the test for 50 years. A cheap simple good design, nothing more nothing less. The Ford flathead was the best in it's day which was over in 55.. With all new blocks and modern parts it can barely make 300 Hp. It looks nice in a new retro rod, fiber glass or repo steel 32 body & repo chassis with all the repo 50's chassis parts. That exotic flattie in the salt flats car has more big bucks into it than anyone here with the Rambler mentality would even spend on a whole car or maybe 10-20 cars no less than making an old engine run like that. Nice for an article in a magazine but not practical for any one of us but maybe Jay Leno to buy and drive it once a year for the "My Classic Car Show". Just my 2 cents. I'll just put my regular gas in my 2 1974 Hornets and my 77 Chebby beater. "Doc"
