Exactly!
But that is where the spirit of hotrodding lives. Modification, incorperating non stock/ different/newer engines, drivelines, change what ever you like! Like the first 392 early Hemi in a T bucket! Or two carbs on a model t 4, or aluminum shoes on a horse!!!!
(Lest we forget; the horse is the first internal, hydrocarbon burning thing to make horsepower! It turned hay into power!)
