look thru the links and videos

looks like they incorporated a bunch of the better R07 chevy race engine,
older LS engine,
newer chrysler hemi
and current ford engine ideas into one really nice design. that should be one great engine.
I really wish it was a bit larger displacement but it looks like a well thought thru design.
they designed a stiff aluminum block with 6 bolt cross bolted main caps and a much more rigid lower end to support the crank, and notice the 4 head bolts per cylinder like some fords, this makes routing the ports far easier plus the more efficient port entrance and exit designs, and all ports are nearly identical

OLDER LS design on the RIGHT, NEWER GEN V on the LEFT

interesting engine. wondering why they still use pushrod.. why not overhead cam?

I wonder why they don,t space out the bore center lines to 4.5-5" bore centers , or build it in some modular configuration to allow for larger displacements,and very easy manufacture of a larger engine, like a 12 or 16 cylinder variant, it sure seems like that with a good team of engineers they could produce a basic family of engines that provided a v4-v8- v12 in modular sections with mostly interchangeable components , other than the block and crank

Interesting, so you are saying use the V4 heads on both the V8 and V12 configurations???

How would you cool a V12, seems there would be some problem with using the same setup
as the V8. The delta temperature from front to back would be to high. You would need a
way for the water to exit the back six cylinders and be cooled separately from the front
six cylinders. Maybe even do something by cooling the 6 cylinders on one side separately
from the other side??? Certainly presents some interesting problems.

Someday I would like to build another TBucket and do it somewhat different by using a
V12 engine, extended body and obviously I would have to have a longer frame.
