Info on Revmaster cranks 78mm in 2165cc combo, anyone?

Guys,

I'm currently looking at a 2165cc motor, that hosts a forged Revmaster 78mm crank.

Does anyone have any info, specs, "trivia" on Revmaster cranks.

I haven't found much on the internet, apart from that Revmaster used to be old school and good quality back in the day. Today they seem to be into aviation and big bore engines.

In some threads found searching, revmaster gets coupled with Bugpack... wich makes me wonder a bit...

I've asked the seller for some more details notebene, but I tought I'd ask those in-the-know

94x78, FK89, dual Dell'orto 45s, street eliminator heads ported by reputable guy, 44/38 vents, 1" 5/8s exhaust, 1:4 rockers

Any comments appreciated! As well on Revmaster or the combo as such.

Rgds,
