Charger
When the idler pulley bracket finally showed up from BDS, we took the supercharger to Mark Kinser in Iowa to have everything freshened up on it. The Weiand snout had to be re-machined to accept the idler bracket so we had him do that too.
I polished the runners and combustion cambers on the Edelbrock heads. The camera we used to take the pictures didn't work very well, but this is a before picture of one of the combustion cambers.
And this is a picture of it afterwards.
The head ports were a very close match with our intake and headers. It didn't take much grinding to make a perfect match. I was surprised though how rough the port passages were. It took several hours to make them smooth. I remember hearing years ago that guys would smooth the ports until they could pull nylon stockings through them without snagging. If that's a good test, ours would pass now.
The 400 block had very little cylinder wear. I deburred the oil galley and started smoothing all of the inside surfaces of the block. I don't know if this would count as stress relieving it or not.
Eventually all of those layers of paint that we had experimented with were going to have to come back off. Decided to try dressing up the outside of the block as well. Any rough castings were removed.
When we're done, the machine shop should be pretty happy. They'll have very little garbage to cook off when they hot tank.
These aluminum shocks from QA1 are supposed to be the ultimate in adjustability for standard mount replacements. They're dual adjustable. The bottom of each has 2 knobs. One to control the valving of compression. - And the other to control the valving of extension. I hope they work because they were close to $250 a pop/$1000 a set.
