It's exactly what it looks like. I'm trying to come up with more on it myself.
I swear that OHC SBC looks really homemade. If so, someone put a LOT of time into it. The timing chain idlers and stuff look like they were robbed from a 6 banger Jaguar. Found a couple more pics of it: The oil feed lines are very homemade looking, I mean copper tubing? It's an old block, what with the rear oil fill tube and all. Then there's the spliced together valve cover.
Notice the welded on cam journals. I'm wondering if it's not an old experimental setup, the word is Chevy worked on the idea for a while.

That is cool. I wonder if they would have done it to the old Buick aluminum V8 they sold to rover if the outcome would have come out different.
I will one up your SBC with a BBF with gear drive
The Chevy impresses me because someone seems to have built it in his garage.
Repco based their V8 off of the BOP aluminum block.
Cam gear drive and oval pistons
HA!!
I work for a gear maker, these pictures make me happy.
Plus I love the sound
And there's what those oval pistons resided in:
Honda could never lick the blowby problem. But the fact that it ran at all and was very competitive (this particular bike qualified 2nd in its class at the 1987 LeMans race) speaks volumes for their engineering. HA!
Now THAT looks like a machinist's nightmare. Wonder what the advantage was supposed to be?
Obligatory hotlink:
In reply to Curmudgeon:
Cylinder wall thickness, overall length and deck height appear to be the same. The one on the left is a 2.3 whereas the one on the right is a 1.6. I would assume that was the point. The machinists I know from my time as an engineering student probably wouldn't be surprised if I brought them something stupid like that.

The rules at the time restricted bike to 4 cyl. Honda wanted to run a 8 cyl. They basically made a 4 cyl. out of a 8 cyl. by taking the middle out of each pair of cylinders.
It never did well.
