Chis,
The best practices are incorporated into the designs of both Great Plains and
Revmaster. Lots of good info on their web sites. GP has manuals on conversion
which I bought and use.
One other expert was a man called Bob Hoover, but he has passed away. His blog
might still exist. He had some serious issues with the Aerovee VW design. I
don't believe their prop hub design is anywhere near equal to either GP or Rev.
But it is another option out there.
My engine has components on it from both Rev and GP. Rev case and crankshaft.
GP dual spark plug cylinder heads. Rev dual ignition (bendix mag). Converted to
use auto spark plugs. Revflow Carb. I feel pretty good about it's reliability.
Biggest reliability issue on Type 1 VW is probably the cylinder heads. They do
have a limited life span running our engines at high power settings. Plan to
replace them as needed. Steve Bennett at GP state this regularly.

Subject: KR> VW type 1 questions - best reliability
After reading the VW heads topic, I am wondering what the main reliability
issues and best practices are on VW currently.
Looks to me that the crankshaft should be forged, heads not cracked (are there
best source for reliable heads?), apply best cooling to heads possible. and
something about the front #4 bearing.
Not sure about anything else structural, and what is best ignition, mag or
electronic, etc.
It is a way off but wondering about this because after 55+ years I would think
that some "norms" and best practices would be out front by now to keep the VW
type 1 turning... so thought I'd ask generally and see what info/experiences
comes back for my KR Saves folder for future reference. :)
