Help identify piston kit
« on: February 11, 2022, 06:35:38 PM »
Picked up a batch of 750 items and tore down to fine domed pistons and it appears to have been boarded too.  Help identify the Pistons please.

 They look like my 812 kit Venolia maybe? 64mm I bet.

Or possibly MTCs. Can you get the camera of your smartphone under the pistons and take a picture.  That would give a big clue.

What bore size?

I’ve got a NOS set of high compression Venolia 836 pistons I can compare to tomorrow night(I’m away)

Just measured bore and it's at 65mm. After looking at other  piston kits I'm confident they are the MTC

Those ribs are dead giveaways, standard Alcoa forgings used by MTC.
