[40 Deluxe]

"casting techniques not good enough"? I think it was more of a sales technique! Design an engine capable of say, 450 cu. in. but start at 332 cu. in. That way you can make it bigger over the years without having to design a brand new engine each time. So we have the Y-block going from 239 to 312, the little six going from 144 to 250, the 221 going to 302, International had a V8 design that went from 266 to 392, and the list goes on.
