Bubba may not be too far off base with his engine. Two of the fastest and consistent winners in our Midstate Club are running 230's and they were built by a gentleman who has raced every generation of 6 cyl for about 40 years. I am not about to tell him they don't work, especially as he is blowing by my doors. He likes the torque and smoother performing engine with the 230's and believe it or not, he has run up against small and big blocks on the track and won. Mind you, he knows his car inside out for handling, etc. but that comes with experience.
Good Luck.......Don
