What kind of V4 do you have in your Classic Motor Carriages TD Replica that is making 180+ hp?
I only know of two V4’s made for automotive applications: One was a 2 stroke (oil and gas mixed) made by Saab and the other was a Vesco V4 which was a specially machined V4 made from a small block Chevy for USAC Midgets (open wheeled oval racers).
