HKS 264 specs

[DSMcamaro]

I bought a set of used HKS 264's and am looking for all the exact specs on these cams. I search and came up with nothing. I also check HKS's website with no luck. Any info would be greatly appreciated.

Thanks! So is the intake Valve Centerline is suppose to be 103 or 105? I'm assuming 103.

I have an actual HKS cam card and these are its specs. These were bought new 2007.. Why is the centerline different than the above post?


264 Intake
Max Valve Lift - 10.3mm

Valve Centerline 105 deg

264 Exhaust
Max Valve Lift - 9.8mm
Valve opens at 42 deg BBDC
Valve closes at -12 deg ATDC
Valve Centerline 121

I know these cams aren't the newest mod around, but can anyone clear this up ?
