ive had several cams in my evo and the bigger the duration mixed with *for us dual cam folk* how advanced or retarded the cams are in relation to eachother and the oem 0 degree mark on the cam gear is what makes us sound like a coughing old man!
when i popped in my hks 272 degree duration with 10.8mm lift on intake and exhaust cams set at 0 degree's on the cam gears the car sound stock as hell. then i played with the variable valve timing on the ecu and advanced it a few degrees and now my car sounds like a mean camed domestic....only with half a motor lol
