Would you resto-mod a Bizzarini with any other motor than the chevy block, or a Monteredi with anything other than Mopar/hemi?
As Doug mentioned DeT was using Ford Power before the Pantera and after his contractual obligations ended in '74. Ghia cars had many variations on powertrain. Detomaso cars had only 2 few exceptions that I know of: Dick R's Chevy powered Mangusta and the 6cyl Pantera.
