looks like it runs with an exposed belt, but perhaps has covers like their larger engines below. It'll need lots of space in the engine bay.

I'd off like to seen them chain driven instead off what looks like a Lego set up

That would add huge expense and complication to seal up the entire front of the engine.

Belts work although the pulleys do look a little small and wrap could be better

I'd like to know what the bang for buck would be
Or could you get more hp with somthing like the Lexus v8

It looks really good but I can't see it taking off. Surely there are simpler and more cost effective ways to making power. A turbo springs to mind.

Probably very small, as there's no doubt they'll be bloody expensive.

But it is still good to see some innovation with the old engine.

Arao Engineering used to advertise 4v heads for SBC, LT1 and LSx engines. They cost a fortune, didn't flow much better than well specified 2v heads and the company ran into difficulties...allegedly.

If you want a proven multivalve chevy engine, get an LT-5 or a Northstar. Lotus developed the LT-5 and some of the engineering carried over into the Northstar. There are over 6,000 LT-5 units out there, so any problems would have been ironed out. True, aftermarket parts aren't that plentiful and the engines are 25-years old now (God I feel ancient). Eaton 122 superchargers for the Northstar units are in plentiful supply at £600 including the chargecooler.
