Thread: Looking for a TH350 Adapter to a Corvair Differential

  1. #1

    Looking for a TH350 Adapter to a Corvair Differential

    Hello everyone,

    I am looking for an Adapter - used in some V8 Mid-engine Kit cars from the 70's and early 80's.

    The adapter mounts a TH350 to a Corvair Differential - placing the engine right behind the driver's seat.

    Please NOTE: (I have been searching for a while and I have already tried)

    a) Clark's Corvair - they only have one for a Powrgluide

    b) KENNEDY ENGINEERED PRODUCTS

    c) Fiberfab US

    d) I've sent an email to a guy named Jeff - on his site he talks about someone haivng made one....


    Thank you, Tony

    Now that is really "old school". There is a guy in Tampa who builds this sort of thing. I see him at the cigar shop in tampa every now and then. He works for the Tampa Police Department. I will see what I can find out for you. His name is Officer Bush. No relation to GWB.

    I found something that might be of interest to you.

    http://cgi.ebay.com/ebaymotors/aw-cg...m=360080685089

    It is a 355 positraction set up for a Corvair. I asked if he had the adapter you are seeking as well.

    Regards,

    Dave

    More Information:

    I have a friend out by St. Louis that has had a Crown conversion '65 since about 1967. He had a Paxton blower on the flat 6 before that.

    Using any heavier engine to the rear of the transaxle will increase the Porshe-itis of the car. If you don't know what I mean talk to a Porsche owner; especially the older cars. The last thing you want to do in a hard corner is lift off of the gas. If you do you will instantly be pointing in the other direction. You basically have to relearn your high performance driving skills to quickly drive a heavily rear weight biased car.

    The Crown kits made the car nearly perfectly balanced and they handled like go karts. With all of the high tech heat and sound barrier products available today I would think that you could keep the interior of the car very comfortable and reasonably quiet. You should be able to make it lot quieter than the old Chevy and Ford vans of the '60s where the engine sat between the front seats and just had a fiberglass blanket under the engine cover.

    My above mentioned friend did the complete Crown conversion to his '65. His first engine was a '64 Corvette 327/365 horse. In the early '70s he bought a new over the counter '70 LT1 350/370 horse and installed it in the car. That engine is still in there. He has never broken any driveline components but you might be able to break something if you put on some sticky slicks and side stepped the clutch on a coated drag strip starting line.

    The 4 speed box was the same Saginaw box used in late '60s small block Chevelles, Camaros and Novas. It just mounted to the transaxle instead of having a tail shaft. It will take a lot but of course with enough abuse anything can fail.

    There used to be a Corvair shop in Ft. Wayne IN in the '60s and '70s. They guy's name was Snyder and he bought a lot of parts from us in the Chevy dealer where I worked in parts. He built that hot Corvair engine used in that dune buggy in the Steve Mc Queen movie. Back then he was building and shipping hot Corvair engines all over the country. It seems like he used to claim arond 300 horse carbed and 400 turboed. Sadly he passed away some time ago.

    G'day from down under, I dont know where you would find an adapter plate, but have you considered mounting a 455 cubic inch front wheel drive assembly out of an Oldsmobile Toronado into the the rear of your Corvair? I have seen a few mounted in corvairs and also in a 911 Porsche, very easy conversion and you can get these bigblock engines to really hammer!! Plus the motor only protrudes about 10 inches into the back of the Corvair rear seat section. Have a nice day, Frank down in Australia.

    Tony:

    Bush was a no go for the adapter. He used a Porsche transaxle and screpped his corvair parts. Here is another source I am following.
