John,I never meant to say the V is a dog.My motor is 446CI,9.5CR and makes 555HP at 6100 with a single 950 holley.I have had a few V motors on the dyno and they all gave up around 6100 with the factory single 4.The 2-4 tunnel ram pulled all the way to 6900.What I was saying is if you put the same setup with a RAIV head with the same flo numbers as the V head,the IV would make more HP.I have not done the compare my self,just from a eduacated guess.Tom
