Feel another longstroke project coming on!
Have enough bits left over to build complete spare engine, less rods
Have come across a pair stamped 67-220 claiming to be long stoke rods
Parts list & in my running '49 engine are 67-228's
Very early '47 engines used 67-219 which I assume to be the one piece rods
so sequentially at least they are in the right kind of ball park.
Big & small end diameters seem right having offered up gudgeon pins & crank less shells, not sure about length.

Cannot find any reference for 67-220's on internet, Bacon books etc., any ideas?

Hi Rusty, these rods were on flea-bay recently and didnt sell, might be worth e-mailing him and seeing if they are still available.

Thanks Brian

I actually have the rods & will find out sooner or later if they fit.
Was just curious as to part no. as cannot find anywhere.
I have a '49 BSA parts catalogue, was wondering if it appeared in earlier editions,
 or anywhere else for that matter.

Rusty,
           I have 7 long stroke rods in the shed and all of them have 67-220 cast in.
One set belongs to a 1950 S.T. and another set came out of a YA7 engine.
Trev.

Thanks for that Trev, very reassuring.
