Operation Torquey-Pig

At the valve. Rarely do you use the cam lobe dimension.
I agree, but when we are talking about different lifters exposing oil bands and such, it is the direct lift at the the lobe causing it. That is how I think about it to take rocker ratios out of the equation. I'm probably weird that way. Thanks.

I asked because I'm trying to decide whether to pursue a magnum or roller LA block for a build instead of standard LA. If the stock lifter gear could support the cam I plan to run, that saves a pretty penny to put elsewhere in the build. Sounds like it might not be a bad idea just from the taller lifter bore, though I haven't seen a dimension applied to that. Like most things I'm pretty sure I'm overthinking it, but I gotta keep the brain busy.
