Corvair Case sale, 36 available, $100 each.


Below is a picture of 36 Corvair Cases I pulled out of my hangar over the weekend.  I gathered these is the last three years without even trying, just picking them up by running an occasional ad on the Jacksonville Florida Craigslist. I have moved these to the Shop of Dan and Rachel Weseman, where they will be available for sale to supply our builders with an option for getting in the game or making progress on their project.



Above, thirty-six 1964-69 Corvair Cases pictured on the patio between our hangar and house. They have since been moved to the SPA/Panther factory.


Here is the idea: The cases sitting in my hangar don’t support my mission of getting people building Corvair engines. They only do this when they are part of a builders active project. Since Dan and Rachel already process 8409 cranks and offer Billet cranks, and also supply the finest remanufactured Corvair flight heads, having the cases at their shop allows them to coordinate a number of different build options, and integrate these cases into their plans.


Let’s look at a few build scenarios these cases might serve:

Picture a guy who wants to build a 3,000 cc Corvair (3,000 cc engines and parts going out the door.), but has not yet found a core; He could start with one of these cases, have the Wesemans prep the case and bore it, he can pay the core fee on a 8409 crank ( The Wesemans have a number of these on hand) and get things in the works so he can assemble his case at home or at a College.

Picture a builder who wants to get started on a 3.3 liter stroked Corvair (3.3 Liter Corvair, a Smooth Power House): he needs a case, but because all 3.3 engine have a new billet crank, he doesn’t need a crank nor does he have a core fee. Just having a case available gets him started with a 3.3 liter crank order and a group 1300/1400 piston-rod-cylinder kit.

Picture a builder who wants one of the Wesemans new “Engine in a box” Kits, (  these cores can support those engine kits.

Picture a builder who sends his case to the Wesemans for modification to a 3,000 0r 3.3 liter, (  but it is found to have an issue that is uneconomical to repair. Such a builder can simply get one of these cases from the Weseman’s rather than go back out and look for another core.


Keep in mind that for $100, the cases are not “mint”, they are serviceable. Most of them need at least some studs replaced. Good news is that the Weseman’s are experts at this. They can prep any of these cases to make sure it is ready to be the foundation of your Corvair Flight engine.


There are many ways these cases can serve a wide variety of builders plans and needs. If you have questions about how one may serve your building needs, please contact the Wesemans :





Just in case the guy at your airport who has an opionion on everything but obviously knows nothing, has a comment about Corvair cases, let me share a little factual data: Both Continentals and Rotaxes are good engines that work, but they have astronomical prices on parts by comparison. Neither of them have a spotless record on case issues, and when they have one, it can cost an astronomical amount of money to solve. For example, ten years ago, Rotax 912’s an engine that is relentlessly fictionally  portrayed as always going 3,000 hours between overhauls, has a serious case issue, where a great number of them fretted the case to needing a replacement in less than 1,000 hours. The case on these engines is more than $5000. Read the thread below to understand that it was an issue that could be caused by issues as slight as excessive prop pitch or even unsynchronized Bing carbs. It was not usually covered by warranty. Rotaxes are fine engines, but they are not for people on a budget:


Lest any expert claim that Continentals are “inexpensive” Look at the two adds below, the used case on barnstormers is $1200, the one on Ebay is $2,000. These are not rip off prices, they just represent market values for a high demand, limited supply item:

The next time anyone wants to tell you about magic engines that have no issues or how inexpensive other engines are, please understand they are just speaking of unicorns: Unicorns vs Ponies.







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 and in more than 50 magazine articles.

    You are so right William! I am helping a friend get his old Breezy ready for flight after many years in storage. He has replaced his Rotax 912 with Corvair because he likes my Corvair powered Piet. The Rotax was was just to expensive to rehab. Thank you again, and as always you “know”.
