Percent of lost lift due to 58 degree lifter angle?

Yes, that’s good to know. Thanks. By the way, the Harland Sharp tech said they make their 1.6 closer to 1.7 to account for that.

That’s at best a fib. All rocker arms flex. If you build the rocker to whatever the nominal ratio it will be less when loaded.

So they do build their rockers with a higher than nominal ratio but not to account for pushrod angles.

How do I know that as a fact? Because every HS rocker I’ve checked has been a higher than nominal ratio. That includes GM rockers.

And every Jesel and T&D rocker is the same.

Like I said, that’s a fun at best.
