John Kruckeberg > Is there someone that is doing the machineing to the corvair heads to allow two plugs?
That can be done, but nobody bothers. Spark plugs almost never fail (although they have been known to blow out of the hole), and even if it does, it's just an annoyance when you have five more cylinders left. Steve Makish flew home on five cylinders in his KR and almost didn't notice! Try that with a VW. What most people run is a dual point distributor with the two sets of points separated, and two separate coils joined by an MSD coil switcher. I have what I call "the almost totally redundant fuel and ignition system", and it hasn't failed me yet. There are some details at http://home.hiwaay.net/~langford/electrical/ . I think most VW guys wish they had a Corvair, because it doesn't weigh that much more, but has a lot more power than a VW. The KR is hard to beat from a modification standpoint, and is almost certainly the cheapest way to go so fast. More biased opinions are at http://home.hiwaay.net/~langford/kopinion.html ...
