Not much to say here on the final day , this is a one of a kind rarity that hits the market on few occasions, typically in a car . This motor is not only rare but increases the value in your period rod 3x if not more .
Good luck on the final day and as always reach out with any questions comments .
I’m retired so able to help with shipping, even deliver if necessary
Cheers

Heads are ardun
Do you know if these were original Ardun heads or reproductions?
Hey guys
Motor is new / fresh build ( Cotten workman ) since passed . I have his hand written build spec .
The motor was aquired and held in the Munz collection for years until Richard’s passing . I’ve since purchased his motor collection (gurneys , cammer and ardun )
I had plans for one of my model b cars but I just enjoy looking at this one .
I’m getting older so my collection is evolving .
I have a custom crate built for the motor and will have the motor in it ready for shipping
can you provide a secure crate for shipping?
it states this is a new engine , never used in racing,ect ?
or what was the motor used in previous to the build?
What is the power ? Do you have dyno results ? Has this been run/broken in ? - thank you
