How agressive are a 252 cams in the 7m? Can you use the stock valve train or do you need to upgrade the buckets,lashcaps, and springs? Im curious cuz i found a good deal on some cams and might be considering it just for a lil extra pep to the motor. Thanks for any help. =J=

I had a thread titled "7M cams" a few months ago but can't find it now, so I can't give 100% accurate information, or even a link.

The general consensus said that cams didn't affect engine power much at all. It will make the engine slightly more efficient at the same boost level, but it won't blow your socks off. One guy said (IIRC) he saw about 20whp gain from cams... but the car made close to 500whp to begin with. I'd say 20hp on top of 500 isn't impressive.
