Fw: <VV> Corvair Industrial Engines

[chevrobilia at juno.com]

Thanks. Sounds like Brent's specimen might have been a leftover Canadair
engine, because the last and largest batch of Dynatracs were built in
Calgary by Flextrac-Nodwell. Canadair purchased FN purposely to go into
volume Dynatrac production which almost happened.

But all Dynatrac engines were two-carb low compression setups, not 140s.
The top shroud was modified (extended sideways) for the larger oil cooler
but the cooler still didn't extend past the head. 

The engines that Chevy built for Calgary Dynatrac production would indeed
have had the cast aluminum pan like we have in the CPF Museum. The bell
housing, though, was stock Corvair.

I have records of all the "End Product" Corvair engines that Chevy
produced. Engines sold for use by boat builders, Cord, Canadair etc. were
handled by the End Products Dept. of Chevy Engineering. They didn't sell
that many Corvair engines in that way, and none had anywhere near the
engineering time put into them that the Dynatrac engine did!

Now let's find a buyer for the Dynatrac in San Diego!!!
