According to Extremepsi.com, Kelford has made a typo on their 280/272 cams for Evos, and they are actually 280/276s, according to them they "never offered 280/272s but it was actually a typo on their behalf"......

Anybody know anything about this? I don't get how a product could be released with the main specs being wrong, not only online, but I've seen pics of the sheet that comes in the Kelford box plainly stating Kelford Intake 280degrees and Kelford Exhaust 272 degrees.

About to purchase my Kelford set, and now re-confused as to what to get.

 

Kelford, the people who design AND grind the cams, aren't going to screw up the duration specs.

 

kelford had a set of 280/272's for the 9. They recently changed their numbering system, as well as their lineup. They no longer offer 280/272's, and that setup has now been replaced with 280/276's.

A buddy of mine has the 280/272s, and I am running the 280/276's. Both have different specs and completely different part #'s

 

How do the 280/276's go compaired to the 272/272's?

The reason I say this, is im running the 272's on a 20G at the moment, but Im about to rebuild the motor to 2.3L, fully build the head and run a trust T67 turbo.. Is there any benifit of running the 280/276's?

Or will the 272's do a better job?
