    If you put a pair of aluminum heads on that 351, You'll have a 40 pound weight decrease over the stock version of the 302 and all those extra cubes to boot!!

    69 Ford Country Squire wagon. 4850 lbs. 429 4bbl, Holley 650 double pumper, 3.25 axle ratio. 0-60 in 7.2 seconds, 15.67 sec at 89MPH quarter mile. 12 MPG typical, 14MPG best effort.

    For all those who like formulas, I remember this one:
    (RPM x Tire Diameter in inches) / (Axle Ratio x 336).
    Meaning at 70 MPH with a 27 inch diameter tire (don't forget tires stretch at speed) and a 3.25 axle ratio, I am turning about 2830 RPM. Not a great way to save fuel. On the other end, the wagon would max out at 5300 RPM. This meant That the car reached a maximum speed of about 130 MPH. Lower gearing might have produced a few more MPH, but at the cost of acceleration. Besdes, the front end was already trying to become airborne: that is, it was very light on the steering.

    I look forward to similar tests with my current wagon (same year, engine, carb but fewer pounds to propel). You never know though. The new wagon's engine may be a bit tired.
