Funny enough this whole engine was build around those crower rods. They are leftover rods that someone had custom made/paid for two sets 12+ years ago and never picked them up. Since the last block had a slight crack in two bores which would allow superheated steam on two rods which destroyed them i needed a set of rods. C-C 6.136, 927 pin, designed for a 2" crank journal, they are B5 style rods good to 1,500+ hp so complete over kill but once again it is what I had.
