push rod length help

I was told for both big block and small block "LA" to look for a straight line through the rocker adjusting nut/pushrod at half lift! But don't take my word for it:)

That's totally different than the way you worded it earlier and might account for the comments. Earlier you said the pushrod would be straight in line with the lifter at 55%. Here's a direct quote from your first post.
The pushrod should be in a straight line with the lifter at that point in travel
Now you say the pushrod should be straight in line with the rocker arm adjuster screw at 55% lift. That last statement I agree with. (well I thought it was supposed to be at 50% lift but that's close anyway, lol)

I think this clarifies things if I'm not mistaken. Funny how one accidentally mis-spoken word can change a whole statement. Feel free to correct me if I'm wrong.
