Looks like 470J series 6 cylinder barrels. 7.7 litres of dependable hp at 2500rpms.
125mm bore with a 101mm stroke. Very dependable motors with rotating exhaust valves. Those motors are long at 3 feet in length. Only drawback is they use a narrow rpm band of about 2400-2600 optimized for reliability. Rebuild every 2000 hours of run time.

I use a rule of thumb that MOST normally aspirated passenger car automotive engines make about 1 ft-lb of torque for each cubic inch of displacement. So for 7.7 liters at 60 cubic inches/liter... puts you at 462 ft-lbs...

ignoring the limited power band.. the trans-axle would be a beast.... (IMG:style_emoticons/default/smile.gif)
