CAM Questions

My 327 SBC was built with the following cam: ES1095M


Here is the description:
62-69 Stage 2 high performance. Use hydraulic flat followers. .050" Duration-224/224; Cam Lift-.300/.307; Lobe Center-114/114. Use high performance spring kit p/n VSA3 or ERV943 springs. 1.700" installed height. Coil bind at 1.160".

When I use this cam in combination with 1.5 ratio rockers, I get a maximum lift valve of 450/461..


When suppliers advertise the lift of a cam, are they using 1.5 x the actual lobe lift? or the lift of the actual lobe?


I am intending to use this same cam with a set of 1.6 ratio rocker which will give me a lift of 480/491. The springs I will be using allow a maximum lift of .550. Am I getting too close to the max or is this considered well within a safe range?

Thanks,

Vic
