I came up with a possibly stupid Corvair related project idea
Posted by: cepak ()
Date: October 11, 2017 07:25AM

A friend of mine is moving and has offered to give me his '64 Chevy SWB stepside
pickup for free (with clean title). He is moving and he can't take it with him. The body is in good shape,
it does need paint but no real cancer issues. The engine doesn't run, but you
can't complain when the pickup is free. It has a later model 305ci V8 with
a 3 speed automatic with overdrive in it.

A Corvair buddy of mine has a spare 140hp Corvair engine that he said I could have
for $200.

Now for the stupid part. I'm thinking of putting the 140hp Corvair engine in the
'64 Chevy pickup. I think it would really blow peoples minds if I showed up with
this combo at a car show.

I know I'll need a reverse rotation cam, but in your opinion, what else would I
need to adapt this engine to the pickup's automatic transmission/torque converter/starter/etc?

Right now this is just a hypothetical since I haven't taken possession of the pickup.

Where are you considering putting the Vair engine? Under the hood or in the bed?

Putting the engine under the hood and remove the radiator.

but it would be so crazy it would be COOL !

I would love to see this adaptation. People would not what to think about the strange noise coming from a very nice looking stock Chevy truck. I think your top speed may be about 55 with the extra weight being pushed.

Are you sure only 55 mph? I'm looking at the original 6 cylinder engine specs,
and I could be wrong, but it may do a bit more.

Tom I think your worst obstacle is lack of room between the frame rails for the width of the Corvair engine. NOTE: I sais 'think' because I have never measured the width in a Chevy truck. Good luck with thinking out of the box!!

EDIT to add that a 4speed trans would give you more advantage of moving the truck. I would guess the automatic trans has more drag.

I didn't think about the width. I'll have to go measure.

Could you use a Corvair PG in this application or is the rotation wrong? You would want to fab a new engine cover so it looks low and sleek. Build it for show and it will attract a LOT of attention, That poor 140 will be pressed to haul the truck but all you need to do is get it to and from a show!

Remember that some fully loaded Ultra Vans tip the swcale at 3800-4000lbs and maybe more. Have to see if either Owen or Danny is reading this thread.

I'm thinking a 350 might be an easier swap...grinning smiley

Having said that, there was a 30's street rod for sale last year, I think it was a Ford Sedan, and that one was a show car. Trunk open, hood open, no engine visible! It was rear-drive Corvair powered. It was so well priced, I thought about buying it and stuffing an LS into it. I could have nearly doubled my money.

Have you measured to see if the Corvair power pack fits in the stock orientation.

With the transmission ending up where the radiator was...like a Cord 8/10 was built.

There was a late 80's Chevrolet S10 with a tilt bed at the Knoxville convention in 2015 with a Corvair power train in the back. I do not have pictures but I am sure someone else does.

I saw it, didn't talk to him but someone told me he's had it that way for years.

Back in 1976, at the Central Coast Corsa Mini Convention... 2 guys showd up with Model A's with Corvair engines up front. I don't recall if they were front wheel drive like the Cord 8/10 or if they where rear wheel drive.
Regardless they were extremely cool. Wish I knew what happened to them!

I say go for it!

Just looking around and found base weight of 3800 lbs. You subtract some for the lighter Vair engine. Gear ratio for that model is 4.10. I still think it would get to 55 but not much more unless rear gear is brought to 3.55 or so. I remember my dad's 1962 c10 Stepside as being a dog with the 292-6 & 3 spd. Always loud rear gear or transmission gear noise in cab.

Subtract the weight of the following items that would be deleted and replaced:
Engine
Transmission
Conventional rear axle
Drive shaft
Rear leaf springs
Radiator and fan
Heater core and box
Any power steering items (unless they were to be incorporated.

Whoa! Whoa! Whoa!
I thought that the original idea here was to just replace the engine.
Now we are making him replace the entire rear suspension?

My idea is just to replace the engine. I'll have to measure to see if the
width of a Corvair engine will fit between the frame rails.
