This is some shots of the Orenda duster.

The Orenda engine started life 25 years ago as a turbo big block Chevy.
Almost everything was changed except the V8 concept and the bore spacing.
Orenda claims as much as 600 HP for this engine although
I notice the HP claims are slipping downwards lately :-)

Note the lower intake for the large area relatively
thin rad mounted horizontally under the engine. Air comes
in below the rad and flow up through it and out louvers
on the side of the cowls.

I had a long talk with the engineer that designed this installation
at SnF who happened to be in the Engineer booth. We were in basic 
agreement about a lot of things.

This is more or less how I am going to do it on the Cruiser
except with side cowl flaps instead of the louvers.
