Doug Dutra may still have his slant six web page. He made/makes cast iron dual exhaust headers and a high performance 4 barrel intake manifold.
You can get a "Super Six" intake manifold to convert to a 2 barrel. The 225 is a great motor. It will never perform as well as a v8. In a 66 w200 chassis the 318 may be the best combination for most trucks. If you want cubic inches (power) a 383 or a 440 from a 68-71 chassis would be the easiest option.
The 2 barrel + Super Six manifold + 2 1/4 single exhaust + the mopar performance cam is about as good as the \6 will do.
Have a great day
