@turboslag Yeah, for most production engines it would be too expensive, but I don't think it would be for cars like Ferrari. My dad used to build Offys for Drake in the late 1960's or early 1970's. I think the Novi might be a combined block and heads too since it was also designed by Leo Goossen. I've only seen the top of a Novi in person, so I am not 100% sure. I hadn't heard of the Hart 415T before. My dad said they blew the intake off Bobby Unser's Offy running something like 90 psi of boost.
Combined head and block is too expensive for production engines, too costly to make as it's tricky to cut and grind valve seats and too expensive to service to the owner for the same reason.
There was a turbo era F1 engine that was also combined head and block, the Hart 415T. Good idea with the boost they ran then, upto 5 bar !!
That is true, but EB always denied it !! Thing is though, Miller got his idea's from a Grand Prix Peugeot engine from about 1910 !! Plagiarism rules in the auto industry !
wow really how much of this engine is original? it is a very nice i love straight 8's and have always wanted to hear a DOHC one, and now I have! thanks for the video.
I always thought it was cool that the Millers and later Offys didn't have a head. I was always surprised more engine manufacturers didn't go that route, especially for racing engines.

On a dyno, huh? And the horsepower is...? And the torque is...?

It is a live work of art
Imagine if those guys had todays tech back then to build these engines.

Sounds so smooth, great engine. Didn't Miller design special valves for his engines? Water-cooled exhaust manifolds?
