sorry 'bout the above rod width lecture, I mis-read panics's entry (it now does seem right). The wider rod "overhang" would act as a "hood" to prevent too much oil sling to the cyl walls.
How strong would the Jag rods be? Some of the smaller mowog motors (MG,Austin-H,etc) have a weird 45 degree cap placement. Jags are a long stroke motor but not with very large bores (thus maybe not seeing as much piston loading as American iron).
I would have to guess the 292 rods may not be the answer for a shorter compression height. Which is desired -why?- to lesson the rocking of the piston?, or to raise the ring set further up for better sealing?
