I am sure you are aware that the V4F class is, at this time, limited to modified roadsters. If you install one in some other body type you will run against OHV and OHC bangers. They are much faster. Of course in the blown classes the records are pretty low or nonexistant. All the cars that are running now have Ford engines, save one loser using a Plymouth. Chevy fours were always OHV. If you feel like making chips anyway, I'd look for a Dodge.
