46624 was originally fitted to big woolwich "Aber".



Almost all the GU Nationals started in the 46xxx series (a few were 45xxx), so no idea where 71147 came from.

That's yes I guessed the first one must have been gu as Fulbourn was only a few builds away,


71147 is where my camshafts came from there not a part number there def an engine number as the cam lobes are stamped aswell but the both have as Lloyd stamp too so could be mod or sea engine parts.


46624 I can't remember off top of head which parts were from this engine I have a feeling it was one of the cylinder heads and pos flywheel (I know this has a stamp on it) but will check when finished stripping parts down as I'm stripping down and replacing with new parts as I go so I don't get too many seals and bearings mixed up.


Thanks for info
