Just thought I'd up date on our camshaft development.. I have been running 3 different spec cams, so far it is looking like they are stable enough to market. A few will require a spring change over the stock, and one ( maybe 2, design under way yet..) will work great on the OEM spring. I have had a few issues with my test mule..( my 06) had to change out the front bushings, and then my timing chain tensioner failed.. any ways, should be able to get a few dyno'd in a few weeks. and post some numbers.. My associat and I are trying to push the envelope on spec. and by-god, they perform flawlessly. 11.1 mm lift numbers on some.. 280-290+* duration!! More as I get it.. Thumper
