Corvair Forum

Veeery interesting. Well this needs some investigation. Having not been to many states west of the Misssissippi, I only noticed lower pump octane in the high elevations of certain western states, like Colorado's 85 pump octane. Everywhere else I saw 92/93. Now I need to see why "they" did...

Well, I was able to get the filter off with some creative use of an adjustable wrench and a belt-style oil filter wrench. Obviously there is no way I have torqued the new filter to spec, but it seems close enough for government work. Will certainly look into converting it to a more useful and frien...

As someone had predicted, the problem with my '65 140 engine was a too-small main jet in one of the primary carburetors. The fellow that rebuilt my engine didn't match the primaries (one was 1965 vintage, the other just older), and the carb rebuilder installed a drilled 0.046" jet in the old c...

Stock location for ignition coil on AC Corvairs is horizontal on the rear body panel, just like Gasman has his mounted. Same with '56 Buicks. They work a long time, like almost forever. Just saying, it works, don't trust stuff you hear on the internet! OMG, the coil will fail if mounted anyway but ...

Since today's 91octane R+M/2 equals the old 96 octane RON that worked in the Corvair, I use it in my 140HP cars and have not had a detonation issue. Just me. [/color] What altitude are you running your Corvairs? Down here at sea level we run 93 to eliminate ping. :tu: Sea level give or take a few h...

Sometimes the hood bracket is far enough off center that it will bind on the latch frame. Have someone hold the key turned and then CAREFULL pry on the hood to see if it will open. Not saying that is your issue, but worth a try. Picture indicate a four carburetor 140HP engine. Not that common with t...

Welcome --- I have a "more door" LM that "followed me home" even though I had a convertible. It has turned out to be more fun that I thought it would. It gets more attention than the convertible. Was your V8 Vega a SBC, or did you use the aluminum Buick/Rover V8? In the late 70's...

Stock stud, but what is that nut? :dontknow: I also noticed the long stud stye nut. My initial thought was that the reminded me of the Poly Lock stye rocker nuts but all the components were not there. My next thought was that these were someone's idea of a "High Performance" part. I am NO...

Awesome! Thank you for the quick replies - it is a relief to hear that this is as expected. I have enough things to fix on this car so I was stressing that this was something major. :woo: Yes at the limits the brake drum tilts vs. the brake shoes and backing plate. Fortunately the wheels rarely dro...

Well, I was going to change the oil on my 64 Corvair and ran into a problem. The bolt which holds the oil filter in place is very clearly not in its stock configuration when referencing my manuals. The picture attached shows the issue. Turning the bolt results in the wire (or if the wire is removed...

Stock stud, but what is that nut? :dontknow: Good catch Frank. I noticed that too. Over the years I've had stock and reproduced rocker arm nuts that varied in tension during adjustment. Too tight and I put nuts in too tight box, too loose and they go in loose box and I install nut from tight box or...

Hi All, Firstly new to the Forum and thanks for having me. I'm chasing four (x4) single barrel side draft carbs in either good quality usable rebuildable condition (or as rebuilt items) for a Buick straight 8 project so they need to be matching. I believe there are two different Corvair versions (t...

I'll second using a FULL face shield (they sell simple plastic shields) when using a wire wheel. Trust me it will save you a trip to the hospital and I did have standard safety googles on. The doctor lectured me on use a full face shield. I have never liked POR 15. It is just a cover up. Fine for a ...

I found this on the Aviation Pros site: "The (MON) number is typically 8 to 10 octane numbers lower than the (RON) number. The autogas (MON) octane number is similar to the aviation rating of octane up to 100 octane, according to ASTM D 2700. When you purchase autogas, the octane rating is the...

Thanks 66vairguy.. I do have a 66 4speed with posi and a 69 4speed reg transaxle. I going to replace the 65 trans/diff with. Don't know which one yet. I do have a RB block and 140 heads as a back up build. I've had no real trouble with the YH carb and i have the hopped up hot/cold on the turbo. I m...

It would be difficult to keep a Corvair turbo engine cool on long straightaways when road racing. Cylinder head temperature just keeps going up with long periods of boost. If spending a lot of money and designing a turbo engine from scratch I would wonder about using the LM open chamber heads vs. s...
