[VintageLambo] Miura Power Specs

I was looking at a road test of the Miura in C&D, and they quoted a high output (430 bhp instead of 350) which is par for the course with American mags converting DIN power ratings. They also said that the cam timing was 308 deg. intake and 284 exhaust. Now this didn"t strike me as correct - I looked at my Islero stuff and it cites 288 intake and 276 exhaust. Now those figures could be wrong and apply to the earlier Islero with lower compression engine, rather than the S engine, which I understood to be identical output to the first Miuras, or OTOH, the figures in C&D could be "exaggerated" for the magazine, or a special pre-production spec or something. Anyone know for sure? One thing that makes me wonder about the specs I have, dated November 1969, is that they say my car should have DCOE 20-21 carbs, and as we discussed previously, it has DCOE 22-23. Whenever you look at anything from the factory on the S, you have to wonder if they just ran the non-S stuff through the photocopier - heck, they didn"t even bother changing the redline on the tachometer (maybe they"d ordered a couple of hundred instruments or something). Can anyone confirm that the 350 bhp engine came with one or the other of those cam specs (ie, which one)? Bill
