Hi, I don't have an engine but do have a pair (matching numbers) of 1954 VH crankcases

I have some inlet and exhaust valve blanks, so if you still need a valve and are in a position to do some machining on a centre lathe I may be able to help. The stem would need parting off, collet section reduced in diameter (if that's how valve/spring are retained on a Black Ariel) and the valve ...

2 sets Hartley valve springs purchased many years ago to fit a post-war 350cc iron-headed Ariel. £25/set inc UK postage
1 set of very old stock Terrys VS469 valve springs £25 inc UK postage.

Are you still looking for a good straight 350 con rod for the spare engine you were building?
