In general, once the 265 Chevy was readily available from junkyards Hot Rodders driving Flatheads began swapping Chevies into their Ford cars. The Chevy came stock with close to 60+ horsepower over the ford flathead. Adapter kits were cheap and the Chevy went in with minor mods to the chassis/body. Speed parts were also reasonable. A 265 Chevy with a 4 barrel, headers and mild cam would make a lot more power than a comparably equipped flathead. Looks or Brand loyalty had nothing to do with the decision. I remember in 1954 watching some Hot Rodders swapping a Merc flathead into a Ford just because it was 15hp more. Guys would kill for 60 horse more.
