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?

^Yeah GM is still sucking wind in the gas HD truck engines, even with the new 6.6. Maybe they'll be under rated, hopefully.
As to old engines, what about 351M Ford big blocks, 360 GM truck motors and old 360 Chrysler big blocks.
LS7 is a really big small block too.....
Deck height is the important with large displacement engines with longer strokes. The small block 400 GM is an example of what not to do, as the rod angle on the power stroke becomes an issue pushing the piston against the side wall of the cylinder.
So for this new 7.3 it would be interesting to know the deck height compared to other engines.
Generation 1: "W" Series
The first ever production big block V8 Chevrolet engine was the "W" series, released in 1958 for passenger car and truck use. This engine was an overhead valve design, with offset valves and unique scalloped rocker covers, giving it a distinctive appearance. The "W" series was produced from 1958 to 1965, with three displacements offered: 348 cubic inches (5.7 L), available from 1958 to 1961 in cars and through 1964 in trucks; 409 cubic inches (6.7 L), available from 1961 to 1965; and 427 cubic inches (7.0 L), available only in 1963.
