I am also developing a new horizontal cooling fan built on the 1960 fan planform but made from carbon fiber. The assembly fixture is complete and the molds are being made. I still need to test a prototype first. I'll post pictures and more info soon.
Engine Build Consultation
For those of you that are going to build your own engine I am now providing build consultation. For $25.00 I'll input your engine data in my software program, run the numbers, send you a printout and give my recommendations on any corrections. The software output is to be used as a guideline only; not gospel. I am using this data along with my flow bench data to dial in my cylinder head mods and help match a cam profile to the heads and vehicle use. And the data also has exhaust specs so you can make the headers that will work best on your engine. Send me an email and I'll let you know what engine specs I need. tknoblauch at satx dot rr dot com
Differential Rebuilding and Mods
I can rebuild your differential to original specs or update it with a 4 spider unit, posi, etc.
Here are a couple of pics from a recent update. I added the 4 spider unit, checked and machined the yoke nuts to provide .002" end play. This keeps the rear wheel camber more stable on a late model Corvair. Labor for the yoke nut set-up on a 4 spider unit is $100.00. To rebuild a diff w/ new bearings and the 4 spider upgrade is $200.00 labor. Parts extra.
To drill and tap for the 3/4 pipe plug drain including the plug w/ magnet during the rebuild is $25.00.
As always, if you have any questions just call me.
Taping the new drain hole on the '65 4 speed
Since my '65 trans and diff do not have drain plugs I decided to add these. On the trans I went to the boss on the opposite end of the shift shaft. I moved the hole over a bit to center up on the cast boss. Drilled and taped for the 3/4 pipe plug. The plugs I bought have a magnet on them so any arrant iron or steel particles floating around in the gear lube will be picked up and held until I drain and renew the grease.
I also added a bronze bushing to the opposite end of this trans to tighten up the shift shaft. I felt it had too much play and with this would cause the seal to leak prematurely. Now its nice and snug. And smooth.
On the diff I just drilled and taped the boss on the bottom where Chevy had originally fit the drain. Same 3/4 pipe plug as the trans.
Bronze bushing fit to '65 4 speed shift shaft bore.

Custom High Volume Aluminum Cooling Fan
My Custom aluminum cooling fan for the Clark Vertical fan assembly. My fan replaces the simple yellow plastic Austin Healey fan originally supplied with the Clark kit. Designed after both the Porsche 911 and 935 fans, this fan incorporates 9 wider, more aggressive blades with the center hub built to fit the late model Corvair fan bearing. In order for my fan to work with the greatest efficiency, I also modify the fan housing by adding stator blades to the housing and modifying the original 3 supporting spokes. The original spokes greatly restrict and disrupt air flow into the fan shroud. The new stator blades allow the air to move freely off the fan blades and help straighten the air flow into the shroud.
Soon to follow will be a new aluminum drive pulley with all the same dimensions as the original Corvair smog pulley but with a larger outside diameter. This is needed to drive the fan at a more optimum speed for proper cooling.
The next fan series will be a carbon fiber unit w/ aluminum center section. I am working on the molds now.
A new custom carbon fiber shroud is also available.
Pricing for the replacement aluminum fan with stator mods on your housing is $950.00 plus shipping/handling. If interested, please contact me for more info.

Above are 2 pictures of Dan Gianotti's engine in his GT-3 race car. He is running the vertical fan with my upgrade aluminum fan. I powder coated both the fan and housing gray.

Custom manifold to adapt a 2bbl Weber onto a 140 head. Carb is actually a 38 DCNL; decided not to use this carb.
Custom vertical cooling fan in aluminum. This is my prototype fan on my 1985 built 140.
