Just inherited a 66 Crown Conversion
Posted by: David V ()
Date: May 12, 2022 07:49PM

Hello- I just inherited a 1966 Corsa with a Crown Conversion, it has been sitting in my in-laws garage for the past 46 years untouched. Unfortunately, my father in-law passed away with all the knowledge of what was wrong with the car. The general consensus from family members is that it was parked due to rear end issues. The transmission and rear end are out of the car. I am in Monmouth, OR and am looking for a fellow Corvair owner with a Crown setup to glean information and possibly a mechanic. Any help/advice is appreciated.

Welcome to CCF. Among suggestions look at V8registy.com

This is watercooled Corvairs around the country. There are V8 owners in Oregon and Washington state. They can help with mechanical as well as possible history knowledge of your car. Also there are local clubs around you to join plus CORSA. www.corvair.org

Good luck with you car.

best wishes, Steve

You are in luck!
The Crown Kit uses the Corvair Transaxle, so any Corvair Mechanic can work on it, you have a HIGHLY qualified Corvair Transaxle Rebuilder right in your neck of the woods.

Thank you for your replies, I have luckily already talked to Rex and plan to have him look over the transaxle and hopefully will rebuild if necessary. Does anyone have experience with a SBC Corvair and longevity of the transaxle. I don’t want to have to worry about it failing over and over. Most stories with this car involved drag racing, so obviously that caused the continued failures with the transaxle. Thanks again for any advice and information.

David - The enemy of the Corvair transaxle is torque. The Crown conversion with the possible exception of the shifting system, is a good technical solution - In the last 50 years, though, engine technology has created displacement and torque solutions that have passed the Corvair capacity. Using the converted Saginaw transaxle (the 66-69 Corvair model), you can make the car live on the street with maybe 350 lbs feet of torque. To do that, you "can" do some things, but you "must" do some other things. If the front of the trans is carefully rebuilt to the non-Corvair input shaft, as scrupulously aligned during installation, it will probably be okay. The list of mods to the differential is where the time and money must be spent. Drag-racing may overwhelm the diff, no matter what you do. Beefing up the diff, with a 4-spider conversion and external stiffening, essentially match- drilling a steel plate on top of the diff. For good advice, I recommend talking with Mike Levine in the V8Corvair and Corvair Racers Facebook pages. He has made that diff live in a tough environment. If you PM me, I will give you his email address.

WELCOME!!! Please keep us in the loop on your progress.

As long as you never ever dump the clutch you'll be okay.

I did everything that could be done to a differential.

On my Crown car in the nineties and didn't break it.

There are a few stronger alternative upgrades.

Lots of C5 differential ways to go out there.

Plus Porsche 930, G50, or Turbo 4 speed.

But that requires some fabrication skills.

Using your current Corvair shifter shaft four speed with C5 can also be done.

You could think about going to the Corsa National Convention to get ideas.

There will be plenty of V8 cars there with a planned V8 Registry meeting.

Plus there are a couple excellent well attended PNW events every year.

My point is look at everything out there before you spend $$ money.

Thank you for your responses, the project is overwhelming, but motivated to get it back in the road. If any of you are within a couple hours of Salem, OR with a Crown conversion, I would like to meet up and take a look and make sure I have everything I need to put it all back together. Thank you.

I would dig looking at your car but I am in Central California.

For inspiration this is my Vairy V8 Crown car autocross ready.

David V I just took a quick pass through the registry and counted 10 V8 members in Oregon plus a number in Washington state. You need to find them, they will not find you. That is why I suggested yesterday you look at the V8registry pages and join the group so you can get help.

I will also agree with those who ay gentle on the clutch. The father/son Harlan Clburn /sr and Jr who autoxed their Vrown V8 with 383ci stroker with a B&M supercharger had very few gearbo troubles because Harlan Jr waited until the clutch was out before gassing the car. They took several FTD (Yenko Award) at national conventions as well as qualifying for the SCCA runoffs for many years.

Little update, got the motor out, that was fun getting it out the passenger door with limited space in the garage. I attached a couple pictures for fun. The first is us trying to wrangle the motor, we were able to get a cherry picker through passenger door and got it out. The second picture is of the car in the garage after we cleaned it up. The last picture is how it sat for the last 46 years. I will try and post photos separately.

Well David there are no pics but I have to say I hope you removed the door before pulling the engine.

Congratulations to you for digging into the car. Looking forward to some pics
