RAVE says that the 190 cam provides different valve timing. That’s not the same as increased lift. There is no mention of lift. What you’ve seen in tuning circles Mat appears to be uninformed gossip.

Well Crispin, don’t you think these “apparently knowledgeable sources” should declare from where they got their information? If it’s true, then why isn’t it in the comprehensive press release which you’ve quoted?
Mat; if you have both camshafts in stock could you measure it for us please?

A check of the Rimmers catalogue shows that the part number for both inlet and exhaust cams is different for the ZT 190/180 engines to the ones on all other KV6's.

No-one can conclude that the 190 camshaft has increased lift simply because it has a different part number.
