The pistons have a different compression height to make up the difference in the bore. If you are serious about building a 400, I suggest you contact Tim Meyer, http://www.tmeyerinc.com/ . He sell a great set of pistons to match the Aussie heads. I bought my heads and pistons from him last summer. Still haven't fired my motor yet but it should be a stout little mill. I have compared this motor to my 393W in my Bronco on the Desktop Dyno. Should make about about 100ftlbs more torque and about 75 more hp...on pump gas...
I'm more of a Chevy guy when it comes to motors. Always did like the parts interchangeability (Plus when your poor always cheaper to build) But when it comes to truck motors (Low end torque) Ford motors are the best. One of the best towing/plowing trucks I've ever owned was a 87 F350 stakebody with a 460, 4spd. The last year for the carb. Used to pull 7000lb truck and trailer in fourth gear going up hill at 25MPH.
My second favorite would have to be the 300 in-line 6. Talk about run for ever.......Now I'm thinking I should go out and find an old Ford!!!
