That gave me some new insight on my pro cons for a 5 vs 6 speed. I would like to have a nice lobing cam. I will more then likely have a 4.10 rear end running 26 inch diameter tires. I know I won't get great gas mileage but I do like not winding the engine out when I am cruising down the highway. What kind of mileage do you guys get out of your 5 or 6 speeds? I know there is another forum but that is for stock 440's without overdrive.




I was getting about 12 MPG with a 438" stroker making 535 lbs of torque. in a 4,200 lb truck with the aero of a brick, but I never did much tweaking with the carb, once we had WOT dialed in, I just ran it as-is. I only drove it maybe 1000 miles a year and beat on it hard, so I figured 12 MPG was pretty good for what it was.
