Dang that's cool!

There was a build thread for this motor somewhere ... on another forum I think. Anyone have the link?

Awesome job Cliff! My thoughts on the application of this engine would be in a homebuilt aircraft. Get a plane kit, build it, and have some fun with this bad boy engine  8) And you could probably fly at speeds close to 200MPH with it, and cooling would definitely not be an issue. Just a thought...

Thank you all for the nice complements and suggestions;

I build a little hot rod a few years ago.
 I built a trike last year.
I think this engine would look good in a replica Morgan three wheeler. I could have an electric fan at the back of the engine, pulling air through the cowl and exiting to the sides of the body. I have a huge oil cooler with a separate electric pump controlled by a thermostat to help cool things down if needed.

I don't see how you could put it in a morgan three wheeler without cutting the cowl back far enough to ruin the lines of it. That car was really designed for the tranverse brit/euro twins and singles so jamming a big honking v-8 in there will kill the balance of the car as well.

Instead might I suggest you do something like this:


basically a street legal indy car replica.

start with a 27 ford roadster kit body and frame. Maybe a jag rear and some double wishbone front to replace the straight axle. enjoy open wheel fun.

Impressive but... how about the cooling of the rear cylinders?
Some really nice shrouds fronted by a Magnesium Corvair Fan should do the trick. Too bad, though because it will hide the beauty of the engine.
