Cam duration doesn't have a universal lift measurement location, sadly. Brand cam duration is based on "where this company measures from, and sets their own standard for all cams", so a bit of a subjective art to it. A bit weird, but true. Many companies will swear this way or that is the best way for measuring duration. I think lift is a more valuable measurement. JWT and Tomei are both top notch, you can't go wrong either way. Personally, I went with the JWT cams because I know and trust those guys and their long term experience working alongside Nissan / Nismo factory racing programs and trade secrets, especially regarding the VG / VQ platforms. I'm sure you'll have good results either way once the cam timing gets tuned in.

Nice looking white (?) Z with a big spoiler take a right turn after I passed by. Saw you too late to wave or flash, sorry. I was in a dark grey Z coming in the opposite direction.
