Yeah,an engine is virtually an air pump,so adding another carburetor,was the birth of hot-rodding.Carbs,(as we all know),use volumes more air than fuel. It would also help the "Big 6's pull a little better on the hills,maybe even gain a gear.(With the help of dual exhaust).I know Ellis made split-exhaust for some Diesels..But this dual-intake for a vintage "Big 6 Gasser" is "New news"! Do you have any pic's of the 630?? Please keep us posted! Welcome to the "'Bolt"!!
