[VintageLambo] Engine manual, Camshaft timing

Hello: I recently finished reviewing the engine rebuild manual on the 400 GT site and was extremely impressed with it. Jack, this is excellent work. Congratulations and Thank You! Laust, your work on the Espada is equally impressive. It takes courage to do the changes that you effected. You mention that you have advanced each cam by 6 degrees (approx. 4 vernier holes). I am thinking of trying out the same on my Espada and I just want to verify that you are referring to 6 camshaft degrees and not crankshaft degrees. If this is the case, then am I correct in assuming that the intake now opens at 44 degrees BTC as opposed to the factory setting of 32 degrees, the exhaust closes at 20 degrees ATC as opposed to 32 degrees and the resultant valve overlap remains the same? Also, are you using 32/76, 64/32 as your starting point for the 6 degree change? Jack, on page 61 of the engine rebuild manual I notice that the valve depression for #6 intake is greater for the Espada and Jarama engines as opposed to the 400 GT by 0.90mm. However, the settings for #4 exhaust, #8 exhaust and even #9 intake are exactly the same. Why Lamborghini recommends a different setting on only one camshaft is peplexing. Any suggestions? Thanks.
