crane shaft mount rockers
all in a nicely packed box
one cylinder set up
rocker has a polymatrix bearing. no needle bearings means less friction loss.
Rocker stud towers had to be cut down .170" to fit the shaft mount. the holes had to be drilled and tapped to 3/8-16 thread pitch.
You can see where the valve cover wall had to be notched as well to clear the rocker. Also, on the right, you can see where the bolt boss had to be machined down.
stands on head
rockers installed
some close ups of the rockers. will need the 3/4" spacers to raise the valve covers enough to clear.

vinci already has some test results from the C6 R&D car. over the 1.8 quick lift rockers, the 1.7 shaft mounts made 17 rwhp more.
i won't have any before/after results, as these are going on a 408 i'm building
