Pistons

[Whitephrog]

On the top of the pistons in the new Whitephrog is the following:

14289
+.030"
ID2
Made in England

Any idea what brand these might be?

In the total seal ring catalog they list a Hepolite 14289 piston on page 46 Here. It must be a typo but it says 848cc.

And they didn't use a destroked 948 in the Mini and call it an 850?????

Both the 848 and the 948 had a bore of 62.9mm according to Wikipedia here

The bores are the same, but the compression heights are different between the two. The 850 is 1.498" vs the 948 at 1.342".
