I call it backset because that's what they were called in a post I found in here from back in 2012 when someone found them. And I plan on double checking the length when I receive them.Backset? You mean the offest trunnions ? Pushrod length on the SS vs the aluminum is slightly different.
I have 1.8 0.090 offset BBC on my Pontiac- and to get a decent pattern the pushrod ios way shorter than my nirmakl Pontiac rockers. Mocking up the aluminum the same length did not have the same pattern.
