A. That's a very difficult one to answer simply. It will depend on a multitude of factors. In a standard engine, with no modifications at all, the best have got to be the 105 standard cams as fitted to the AlfaSud Green Cloverleaf. They work well, and if you do make some minor mods they will work well with these too.
If you are talking about aftermarket cams, like Piper, Kent Holbay etc, then things are definitely more complicated. The thing you will have to decide is what you want the engine to do. If you want to race on a circuit, then use race cams. If you are going to use the car on normal roads, and you know that you will encounter traffic on regular occasions, then do not use anything hotter than a fast road cam. In between those two points you have to consider a few factors. Fitting road/rally spec or rally spec cams is a waste of time anyway if you are not going to increase the compression ratio and rolling road tune the carburettors to suit, because it will be a dog to drive. Even if you are going to re-tune the carbs and up the ratio, bear in mind that it will be more difficult to drive at low RPM and in traffic. I personally wouldn't fit road/rally cams unless I was going to do sprint events or such other competition things. Cost is another issue, as fitting cams will involve a lot of money for a relatively small gain, and the gains are smaller if you don't do the compression hike and tuning. Your money may be better spent on a bigger engine, or a head 'porting' job which will also partially freshen up the engine.
Whatever, remember that a bigger engine will make a wild cam less wild, and that an injected car is a little more tolerant than carburettors of hot cams.
