The test and tune continues.
I dropped in the 10.5 power valve, adjusted the timing. Better again, almost civilized. Civilized but deafening inside

Seriously you need ear plugs to drive this thing.
Next on the agenda, is the failing power steering pump. Bearings are going, so it's making hideous noises, and the pulley is sliding in and out at least 1/2"
I have the air fuel gauge now, just have to make a revised console panel, to hold it, then hook it up.
Existing gauge layout;
The start button is going to be axed.
I'm thinking switches at the bottom (across) and the four gauges side by side in a quad layout at the top 2/3 of the panel.
Next I worked on installing the new emblems.
Some fitting work, but that's done.
Now I have to decide on orientation.
To the side (side facing)
or to the front.
The problem with the side, is that the emblems are a little hard to see, with the shock towers canted towards the inside. It might encourage people to lean in over the car a little too far?
