[QUOTE=maddog]Cosworth cams may have changed recently but they were previously re-branded Kelfords. Kelford are currently US$99 and US$58 cheaper than Cosworth for cams and valve springs respectively.

that's strange...
the specs vary between kelford and cosworth, so I would say they are NOT the same. ie cosworth are not re-branded kelfords.
MANY people have made good power using cosworth cams with suitable supporting mods.
I was told by a well known local subaru/mitsubishi 'guru' workshop not to go with kelford cams because they don't seem to make the power.
