I see all the cars (Corkvette and Hoover)compared to the car in question have LT1 intakes or Superrams. They also have BIG solid roller cams and Corkvette and Hoover have more cubes. Yet Corkvette runs similar times and Hoover did before the last few rounds of mods. Corkvettes heads are similar to flow I would assume. Either the track that these cars run at is fast; or the builder of that car and looks like another LTR vette knows something that we don't.
