Properly setup Webers will give you better performance throughout the entire powerband, better fuel economy and be just as dependable as a new Edelbrock carb. Not to mention they look SOOOO SWEET!

You will be much happier with a more stock four carb set up on the 140. The 4bbl set up eliminates carb sync but is starved for warm air. Rough running till they REALLY get warmed up.
Corvair fan belts should stay on just fine with proper belt |
Do you have the the secondary carbs with added idle circuits or the stock design. |

Corvair fan belts should stay on just fine with proper belt and tension. Corvair fan belt throwing is fault of owners over tightening the belt. I have owned both stock and hopped up SCCA vairs. I have a built 140 with a hot cam and four primary carbs that revs up to 6,000 daily. Belt stays on. Trick is adjust it loose, should be able to turn alternator pulley with one finger when cold. USE a proper belt too! Clarks Corvair parts has em. |

The Weber version might fit, I think the 4BRL setup would require some fiberglass cutouts.
Here is my Corvair powered Manx with stock carbs and low profile filters:
The stock Corvair fan belt changes direction (around the alternater and an idler pulley) to rotate the top mounted fan from the rear pulley. I think the Porsche style fan would solve the problem some Corvair engines have with fan belts not staying on their pulleys as intended. Plus it looks great!
I'll take the triple weber version please.

| That's correct, the link to the ebay auction I posted has Starr Cooke's contact details. He is the individual who has the Porsche 911 shrouds for the Corvair engine as well as a lot of other Corvair performance stuff. Again, Starr Cooke in El Cajon, California has the shrouds. Its near San Diego. |
Ahh okay thanks. I saw pistons and was like 
edit: found it. Thanks so much.

Where can you find those Porsche fan shrouds for the corvair?

When Subaru makes an air cooled boxer engine , I'll be first in line to put it in my swb Manx. |

SteveManx2, , I have the same combination of short stroke with 140 heads and altenator and Holley 4bl. Not the largest displacement Corvair, but a smooth and cooler running engine, or so I've been told.

How about take a stock 180hp, then reverse rotation, use a modern turbo with a set of Keith Black forged pistons and a set of the Chinese nikasil cylinders to keep it cool? I think that would give you 200hp+ with better reliability than the stock engine and probably not be all that much more expensive than a 150hp Type 1. |

It's a real shame either GM didn't continue development on the Corvair engine to a 3rd generation, or someone hasn't worked on tooling up their own version. An air cooled push-rod 6 is just plain cool!
Unfortunately, by the time you have one outfitted like the pic at the beginning of this post, you'll likely have as much $$$ into it as a real Porsche engine! Factor in the 94mm cylinders, full rebuild, cut heads for the Weber manifolds and revised valvetrain, the Webers or PMO's, Porsche shroud and fan/alt., roller reverse cam.... That all turns into a BiG TICKET motor, likely only pushing about 250 HP or so.. maaaaaybe 300? Then it becomes too hard to keep it cooled while making that kind of power.
A modern engineered and machined bottom end would be the real ticket, with the same modern engineering head design to go with it! Just dreaming though... only mass production would ever make such an engine even remotely affordable.

Still, I think that pushrod 6 Porsche look-alike is downright cool!

Yes, the rear hubs have been drilled....EM Corvairs had 4 on 4.5, these are now 5 on 4.5". The front VW hubs have adapters. The brakes date it to 1962-1963. The motor is a bit of a mystery...the code on the block (T0820YN) indicates 1960-1963 145cid....but it does have 1965 140 heads. The upper shroud is an EM with no provision for PCV but has been modified to fit the 140HP heads. It has a draft tube rather then PCV and yes has an alt. The flywheel, differential, and transmission are all 1962-1963. So, I'm not 100% positive what all is here  The instrument panel and gauges are from 1962-1964 Spyder. The fins on the fan are straight...does that indicate LM?
