Lol grabbing a set of cams from a wrecked volvo 850 will take you about 15-30 minutes TOPS,
1. Remove all securing bolts, you may have to use something to pry it up, or give it a whack on the side
2. Cut the timing belt
3. Remove cams
4. Enjoy in time and 30$ well spent
It is CONFIRMED on the butt dyno to give you slight increases in power
Not to mention the profiles of the cams are more agressive so it makes sense there would be power gains :)
