Looks like lots of room for performance mods! 

"Compared to the Carcano engine, the V9 uses polidyne cam profiles (in the ‘60s they were not there yet) featuring moderate lift—for easier maintenance and longer valve train life—and almost zero overlap."

Looks like they took the aero head and utilized the modern practice of minimizing the surface of the combustion chamber. 

Also, the passages on the spark plug side look to be interconnected.

I just wish they could have squeezed a bit more HP out of it.

I'm scratching my head over the driveshaft.   I could be wrong, but it looks to me like they added another U-joint so that the drive shaft could run constantly crooked, and they made the drive shaft crooked in order to provide room for an over-sized rear tire.

they make it sound like the aero heads were based on a v700 head casting... pix above deny that

yes... no diff than any spine frame or cali 1400, and it does away with the carrier bearing.

It is a Hemi?  I need to go check the mail.

Damn.  I wish we had a Houston dealer. 

Sounds like the V9 is a major upgrade to the small block.

  Yes a low valve angle hemi head....And it looks very much like a early  Harley EVO head.... Most 2 valve designs, including the Dodge hemi. now have moved away from the shallow hemi and have oval or figure 8 shaped combustion chambers for a faster fuel burn with high compression and low octane fuels..
   In the late 1950's the US car makers flirted with Herron heads...The Ford "Mel" engine used in Lincolns and the immortal Chevy 409 (348) had Herron heads.  They were attractive because of good mid range torque....
