More work on 1965 110hp Corvair engine

engine

DETAIL:

I've bought almost all I need for the conversion.  I still need to get a crank, cam, prop hub and distributor.  I bought most of my stuff from Larry's Custom Corvair.  He has a nice set of reworked and precision balanced rods for $145.  Also got a set of TRW forged pistons from Larry's as well for $229. 

I've been doing a lot of cleanup on the engine. A friend of my dad's has a blasting cabinet.  glass blasted the cylinder exteriors, cast exhaust manifolds, and cylinder baffles.  We used AD-6B Walnut shell media for the aluminum parts.  Everything got blasted. The engine is looking like new!

I took an idea from Pat Panzera and milled off the stock intake flange.  It sure makes the intake manifolds clean and professional looking.  I have to build a jig to squarely hold the head and provide a flat surface for the router base to ride along. I made the jig to last.  I figured as time goes on I'll end up building another engine or two and would also be willing to do the mill work for any other Corvair builders. Contact me if you'd like me to mill your heads. Soon I'll have a 90 degree aluminum pipe welded into place.  This method shaves some weight and reduces the overall height dimension of the engine.

Also, I've taken the extra effort to grind and polish the intakes like Pat has done.  It's a lot of work to get the looking good but the results are well worth it!  I want my engine to look show quality.  I plan on entering my ship in experimental fly-ins  and want to be able to show off every part.  My engine will be polished and color coordinated to the plane.  Several key elements will have blue and black paint.

Cutting off the stock intake flange



 First pass on the intake.  Each pass removes about .05"


After 2 passes

 

The router in action.  A carbide bit cuts through aluminum like butter!


This head is completely milled.  Perfectly flat and ready for the intake tube to be welded.

The messy aftermath. A bunch of aluminum chips
