It's been a couple weeks since an update. Things have been going on in the background getting the intake system lined out. A couple hours yesterday and another today went into operations with the die-grinder, hand water-sanding, and polishing on the intake manifold. Not what you'd expect from a top-shelf restoration house, It'll suit the little Sport Truk just fine.
This is the manifold with all casting flash blended, surfaces buzzed down, and sanded with 220 grit paper:
Next step was water sanding with 320 then 400 then 600 papers, polishing with cotton wheel and buffing compound, and hand polishing in places the wheel wouldn't reach:
Care was taken to preserve the little Hitachi logo cast into the front intake runner just forward of the carb mount. This photo shows the stack-up of carb, manifold, gaskets, adapter, and phenolic insulator:
Here's photo of the manifolds with carb adapter fitted up to engine with gaskets:
More to come on the final bolt-up and PCV system.
