My 360 Duster, with about a stock 340 cam, gets better gas mileage with a 750 DP and 2.94's than my 318 Duster with 2.76's. Both have great sealing valves.

Well thats crazy! But, that 318 also has 1200cfm lol. Whats the mpg number on the 360? Love your 318 series btw! Gonna use your homeport guide!
