Here is my 1966 440 mill in the 36 Dodge coupe.It has a Hughes cam 538 lift don't remember the duration at the momement,ported 452s,9.5 squeeze and of course the six pac.Nice running combo not sure of the mileage.When I go on out of state trips I pull the 4.10s out and slip the 2.56 gears in the 8 3/4,that helps in between gas stops.lol Joe
