273, could it be a commando and CAM question?

Be sure to get it on camera, I'd be really interested to see! Nice to see another Swede here at the forum also! I was joking around with friends that I must be the only one in Sweden with this much in to the drive line and such small engine :)

Trapster, lowest octane we have is 95, but I think we use a different scale or reading.

I thought I was the only crazy guy in Sweden who is sticking to a 273 and pays to trim it. But I do not want a 318, it is too common. Would love to put in a 340, but they are unavailable in Sweden. 360 is a truck engine. So therefore I have chosen to invest in my 273 from 65, I decided to 100% when I got hold of a D4B intake.
I think you and I are unique in Sweden.
I’ll post some pics.
The motor pic is from last winter, the headers are in place now.
As you can see in pic #3, the engine compartment has been painted this winter aswell.
