Funny you should bring up; all the errors the traditional guys get obsessed about. Granted the original car
, Stacey David's "Rat Roaster" has an I beam front axle, but traditionally rodders of yore were looking for the smooth look obtained by using the "Tube" axle found under a'60 powered flathead '36 Ford.
As for tradition, things often change, i.e. the venerable flattie, up until the late fifty's the darling of the hot rod crowd. Then , probably the early fifty's some went looking for more power. Remember "If some is good, and more is better, then Too much should be just about right." thus the OHV engines, 303 Olds, Pontiac, yes even a Studebaker V-8. But then along came the little Chevrolet 265 V-8. Cheep, power to weight numbers were up there too, and just about every after market company was on the band wagon.and with the help of a company called Wil-Cap you could bolt up just about any combination you could think of.
So I don't think Revell did so bad.
