New Ford 7.3 V8
I see people calling this a “big block” engine. Is it part of a series of engines of different displacements based on a common “big” block?

I think Ford picked the 7.3 liter displacement to capitalize on the reputation of the old 7.3 Diesel. It sounds like it's built very stout and should preform well. Will be interesting to see what it does in the real world for mpg and performance. My 19 year old V-10 manual transmission is still going strong after 200k miles. I just took it on a 800 mile trip last weekend (solo) and averaged 13.75 mpg.
Same as the rumored "426 Hemi" that Ram will introduce in the 2500/3500/4500/5500 trucks in the next year or two. IMO this engine is the reason the 5.7L Hemi is no longer available in the 2500+ trucks.
The 6.4L will be the base engine and the 426 Hemi will be the optional gas power plant. Much like Ford and the 6.2L/7.3L gas engines. They will market the heck out of that "426". I believe 426 cu. in. works out to 7.0L. So they should be able to get better hp/tq numbers than the GM 6.6L gasser and similar to the 7.3L Ford has put out.
