/// Changing the cam will not "add power". A cam will exchange power from one end of the rpm range to another. Only increasing the amount of fuel in the chamber (turbo or super charger) or increasing the size of the chamber will increase horsepower. A great deal of money is spent on fine tuning the engine and this is good. Some small gain can be attributed to "super blueprinting". Not much, though, is ever gained given the weight of the Volvo versus the horsepower of the b20. There are other sites and I have read that there are differences in the blocks, some being heavier and thus more comfortable to bore out.

Go to the links section of the board. Try the Yahoo clubs 1800 list. Even in this list the racing, when discussed, is geared to skill at high speed not muscle 0 to 60 power.
