And how do they actually compare to std cams?? Offering a power band from 1800-6800rpm...sounds like less than a std subaru?
What duration/lift does a std subaru have. Also an important question is are these re-grinds, or new blanks, and what is the quality of the grind? Are verniers required to time the cams in after fitting, due to poor re-grinds, as buying 4 verniers wont be cheap.
