Slant 6 rocker arm metalurgy

moper said

The only change to a rocker for the ratio is the position of the pushrod end.... So on these stamped/welded steelies, you "could" simply move the threaded section, or remove it entirely and weld a new threaded section closer to the shaft centerline. With a jig, that would be easy and repeatable.

I agree with all of that; there's a straight line (geometrically speaking) from the top to the bottom of those rockers that runs vertically, between the bushing boss on one side, and the flare-out for the adjusting screw, that could probably be cut with a band saw (if the rocker were held firmly in a jig) and "massaged" so that the pushrod end of the rocker was closer to the fulcrum (shaft) by an appropriate amount. The location of that cut would afford you a straight line approximately an inch long on each side of the rocker arm, for a sufficiently strong bead of weld, I would think.

You'd just have to determine how much inward, to move the adjusting screw, and build a jig to hold the rocker and adjuster-end in alignment and in the proper position, while it was being welded.

I'm no fabricator, but that doesn't seem too difficult to me...

What do you guys with t.i.g. welding experience think?
