318 with 675/318 or 974/360 heads Cam Recommendations

Well, I had to satisfy MY curiousity, and so I called UEM about the .060" oversize KB399's.... weight increases from the standard bore weight by 21 grams, to 573 grams nominal. Not as much as I hoped.

Now comparing to the stock weights, AND using the stock pins rather than the KB pins, I am coming up with numbers that are around 20 grams lighter than nominal stock bobweight: 2150 grams versus 2172 grams.. Since reported weights from the factory varied that much or a bit more, it seems OK for a basic hot rod engine.
