Yea, there's that one and a 222/224? high lift also, but not the 216/220 for some reason? Seems like a cam that would respond well to more lift.

This explains why the base circle is smaller.Ls6 cam having bigger lobes are a givin.

With that cam you can use new Ls6 spring for $70,no need for the other ****.You might as well go for the free HP and go with 550-570 lift range even if your duration is in the 205-222 range,even then I would use those springs. 114LC is about the best all around.Do you feel the need to spin it past 6200?

Thats true but the gen1 small blocks are even more interchangable. The head flow doesn't compare though.

If it came out of a regular C5, then it is a LS1, not a LS6. And if it’s a LS1 then I wouldn’t run that much lift with stock springs. I’m not sure if you are considering LS6 spring swap as no headwork or not, but you need a better spring then the stock LS1 springs…
