The 62/63 con rod casting # is C2OE-A; the beam of this con rod
visually narrows from the crank end to the piston end.
The 63, 289 con rod casting # is C3AE-D; this con rod was used on the 64,
260/ 289 and from 65 to 68, 289.
The beam of this con rod is straight and measures .68".
The beam is looking line of sight straight across the 2 connecting bolts not
looking at the crank or piston pin openings. The con rod casting # is near
the crank end between the 2 ribs.
The majority of Tiger 260 engines do not have these con rods possibly all of
them but I don't know that for sure.
Non of the B948 series Tigers would have the C2OE con rod

Subject: [Tigers] Con rods
I bought a Tiger with a 260 motor. It could have been raced, and I am told
the con rods on the 260 are weak and I should change to 289 con rods. This
may have happened already. Can anybody tell me how I can distinguish
between the 260 con rod numbers as opposed to the 289 con rods?
Thanks
