I do believe there is at least one Inliner running tractor rods but I can't remember which ones. It's not the source, it's the specs. With the Jimmy rod journal at 2.311 offset grinding the crank with a minimum bore gets you the extra cubes and a block that can be used again. I wonder what the wall thickness is on a Jimmy 6 VS a SBC? My thought is, how far can you bore a Jimmy before it has the same cylinder wall thickness as a STOCK SBC. Just to make an apples to apples comparison. A 302 starts at a 4 inch bore.
