Engine Cores and Parts at SPA



Every airshow has builders who ask about the availability of core engines and rebuildable parts to work with. Below are two pictures I took in the storage building at the SPA/Panther factory.  The images should demonstrate the availability of Corvair core engines, and also point out that we have complete core engines available for builders working with SPA and ourselves.



Above, one of two pallets of GM 8409 forged cranks to be fully reworked and matched to Gen II 5th bearings. These cranks are destined for base level builds. about 50% of 3.0L Corvairs and 100% of 3.3L Corvairs use SPA’s brand new made in the USA Billet cranks. Read more here: SPA Billet Corvair Cranks. For a look at the three crank options, look at this story: Update notes to 2014 manual, 1000 – Crankshaft group.



Above, piles of heads, cases, and the end of a row of core motors.  SPA keeps a very large collection of head cores to support their high end Corvair flight head program. They have now made more sets of Corvair Flight heads than any other company, ever. From the start, Dan’s goal was to have them available on the shelf which they now are. In years previous, our former supplier Falcon got to the point of being a year behind. This had not been an issue in the years since Dan started offering heads.


The cases pictured are mostly from my collection, featured in this story: Corvair Case sale, 36 available, $100 each.. The picture illustrates the availability of parts, and our willingness to invest in them to support builders in a timely fashion.




Above, a pickup load of complete Core engines I brought to SPA in January. These and others are available for sale now. If you are a builder yet to find a core, but planning on attending the open house next month, it would be a good idea to contact SPA in the next few days to purchase one of the cores we have on hand. All progress on planes starts with the decision that you will take action when opportunity appears.




The Next Event on the Schedule:

FlyCorvair/SPA – Joint Workshop/Open house, May 18,19,20

Read the link now and make a plan today.




About William Wynne
I have been continuously building, testing and flying Corvair engines since 1989. Information, parts and components that we developed and tested are now flying on several hundred Corvair powered aircraft. I earned a Bachelor of Science in Professional Aeronautics and an A&P license from Embry-Riddle Aeronautical University, and have a proven 20 year track record of effectively teaching homebuilders how to create and fly their own Corvair powered planes. Much of this is chronicled at www.FlyCorvair.com and in more than 50 magazine articles.

    The Corvair Movement has greatly benefited from FlyCorvair and SPA coordinating efforts and maximizing each other’s strengths. We would not be where we are today without it. But am I really to understand that getting to state-of-the-art cylinder head production could only be done with violence?
    “In years previous, our former supplier Falcon got to the point of being a year behind. This had not been an issue in the years since Dan started offing heads.”
    Just kidding, I know the back story for your writing style, and only poke fun because I know you can take it. Carry on. 🙂
