New guy here. I recently installed a Holley Sniper units on my mid engine V8 Corvair. It was a complete kit with great instructions. It fired first try and has really added a huge amount of torque in the low end. I'm using a TH425 transaxle from a 73 el Dorado with a 3000 stall convertor. I have a couple of hundred miles on it and It was well worth the price

Welcome to the site.
I gotta say that's the first time I have ever heard of that conversion. Very impressive indeed. I bet it goes like a bat out of hell too!

Thanks Steve

We took out a bunch of weight but added frame connectors….haven’t weighed it yet …figuring around 3,000 lbs.

Still a lot of fun

TOP PHOTO
The Corvair was a running / driving car when the beer hit. Things changed a lot.

MIDDLE PICTURE
While the front motor mount is visible, you can also see the pumpkin ( rear end attached to the transmission ) along side the engine. The piece of metal above the carb is the track to hold the back window in place

BOTTOM PICTURE
The exhaust system. Everything is mounted solid.

We had to make a tunnel in the oil pan for the right side axle and flange

Nice job on the conversion. I have a Holley Sniper unit on the crate 350 in my 1930 DeSoto. It does increase low end torque as you stated and start up is immediate.

I love the V8 conversion Corvairs. Kudos to you. That car must be so much fun.

Please describe your trans set-up.

425 Transaxle...BOP adapter?

Then did you use the Eldo's suspensiion, brakes and etc. Or, did you graft it in to the Corvair? If so, how?

BOP adaptor was to attach the SBC to the TH425 belhousing.

The Caddy drive line ended at the flanges on the pumpkin and the ride side axle flange.

We used the Corvair Trailing arm but no other Corvair pieces. The axles are 10 5/16 inches long with the bolt on Caddy flange on one end and a Corvair U joint on the other.

THe toe in / toe out control arm bolts to the main cross member. A control arm bracket controls the camber in and out. QA 1 coil springs with 450 lb springs complete the suspension. The coil overs bolt through the plated frame rails.

We used an old Corvette drag racing trick where the trailing arms bolt to the body. We machined aluminum bushings so the suspension only goes up and down......no twist


The bottom suspension photo shows the toe control arm. There is a second bar that did not work as we thought it would so it was removed and a traditional style control arm bracket was fabricated. You can see most of the susopensin in that photo

I built a Toronado Corvair in the 90's using the 455 Olds engine and a 67 TH 425 trans which had a switch pitch torque converter. Unfortunately just a few months after I finished it, the car was involved in a chain accident and was eventually totaled. Your car looks great and I wish you many miles of enjoyment.

Very impressive conversion! Nice job explaining what you've done too.

Just a guess but are you running an extra quart or 2 of oil to compensate for the amount that is constantly trapped in the front of the engine (due to that pan modification)?
