4.3L V6 to modernize the Corvair.
Posted by: anthonyforensics ()
Date: January 19, 2010 05:46PM

I am posting this as a continuation of the post [corvaircenter.com] titled "List of v8's... which would go best with a Corvair.." The idea of a 4.3L V6 seems very realistic so I am looking for more information. So far we have had some GREAT posts on this topic. I would love to get a lot more pages. I also would like to know what motor mounts would work best.

See Tom Z's thread on the mid 4.3 build. I have an Astro with a 4.3. Really great motor. I can see why someone would want one in a 'vair. I've been tempted to keep the motor when the Van dies, to stick in a Vair, but it's the post '92 with the counter balance shaft.

The best 4.3 would be to use the older tbi hydraulic roller cammed 4.3 shortblock
(these were also used in the GMC Typhoon/Syclone) with the newer Vortec heads.
There are a lot more performance parts available for the older tbi engines as they shared more parts with the typical 350 V8 than do the newer Vortec 4300 engines.

The Marine 4.3 I listed from ebay is unbeatable!

$1301 buy

$199 core

$175 shipping
--------

$1,675.00 longblock delivered.. reverse rotation!

They most likely come with a pan, and most likely have the correct RR distributor.

And intake manifolds are a dime a dozen!


In 2--1 my son bought a running '88 4.3 for $150

Threw rings and bearing, etc .at it..

Custom cam / intake / carb / distributor from ebay...

Had $900 in it when done..

I used early 70's style V8 motor mounts on a Transdapt crossmember with "L" shaped plates hanging from the side rails.

This is awesome. I am definitely going to start this project. I just bought a house and drained a lot of my bank account, but should have the extra funds in a few weeks. Keep the information rolling. Matt, thanks for posting the ebay link. I went to the manufacturers website and found they have them ready to ship anytime I want to order. I hope to order in Feb. Thanks everyone for the information. Ed do you have your car running? Did you use a VW transmission? Tomorrow I am going to print a copy of this post and the v8 post so I have this all documented.

"Ed do you have your car running? Did you use a VW transmission?"

No. My cars and tools are spread over two counties so I haven't had a chance to fininsh it.
The trans is a '66 3sp and the diff is the '66 3.55:1 from my old V8 car. It has a 4 spider conversion.

Matt, the engine that you posted states "Standard rotation"... does this mean that I would have to reverse the rotation?

Does anyone know if there is an Aluminum block version? I want to say I remember reading about a NASCAR Busch Series motor that used an Aluminum 4.3 block, but that's been a few year back, so I may be wrong.

Yes, there's a GM Performance Products (GMPP) aluminum version. My machinist has one and we're talking about him storing some of my money while I store his aluminum 4.3... I hear new ones are pretty pricey.

Thanks Craig. If you get any idea on price - please let us know, just as a base line. I have a buddy that works for a company building boats, and he says he can get any Rev-Rot I would want. While I haven't challenged him yet - this thread is making me think about it a little more.

Here is the response I got from the company on the E-bay ad when I asked about reverse rotation.

"We looked into this before. We coudn't find anybody in the industry that made the reverse rotation timing gears. We have done a reverse in a later Vortec roller cam marine engine but that engine wouldn't bolt right in your application.


- hiperformer"

Might be good to check and see if the Vortec they refer to is a 4.3 V-6 also. By not bolt in, do you think they mean the bellhousing or other factors . . . I guess I could ask.

Wow you actually got a response from a company! At least they did that for you. Ive been emailing Kennedy and Clarks for a week now and they wont respond. When I called Kennedy they were very unhelpful. Its as if these guys dont want my money. They say were in a recession but I wonder how much of it was caused out of laziness and not willing to go the extra mile. Sorry prolly not the place for this rant.

I wonder what they meant that it wont bolt right up? I wonder if they knew there would be a small block chevy adaptor involved?

Mike

If you dont mind ask your buddy if there is a reverse rotation Chevy Ecotec motor available? Ive never heard of one but I think that would also be a suitable and economical conversion for the COrvair that could bring it well into the future.

Thank you
Damian
