The major remaining issue with the high compression engine swap is the battery charging circuit. I've tried 3 different alternators so far, and all produce no output. The testing procedures in the Bentley manual lead to all 3 alternators being bad... but I just have a hard time believing that. What I need to do is take the alternators to an Autozone (free alternator testing!) so that I can be 100% certain. The wiring is so darn simple with these things, that I'm basically stumped.

On a more positive note, the motor runs great with the Techtonics 268 camshaft and the ignition timing close to correct. Some of you may be wondering why I chose the TT 268 over the 270. The 270 has better idle characteristics (close to stock, actually) and fantastic power gains. The 268 does have a little more lift, but I chose it mostly for it's large valve overlap period. It is also ground with an offset to favor top-end power. The larger valve overlap should really favor high compression applications like mine. Had I kept the factory compression ratio, then I would have chosen the 270.
