That is a big pet peeve of mine, the habitual SBC in every early Ford, that just gets me going, if you want a damn Chevy, build a damn Chevy, but I'm far less offended by a Hemi of any kind, in any early Model car, regardless of year or make, even if most are only just reproduction clones anyway, not even real Fords, or what ever... Go figure... It's the easiest {Parts availability/cost, oil pan sump interfering with the steering & width/length issues usually} & the cheapest way to go, but you put a ton of money in something like that , why not go the extra mile ??, put in the proper drive train, to match... I am always amazed, when I actually see, a Ford engine, in a early Ford, what a novel concept...LOL...
