That's the part number and casting date for the intake. If I'm reading that correctly the intake is from a 66-69 273 engine. The casting number for the engine block will be on the driver's side, below the exhaust manifold.

Basically no-one bothers to work on 904s anymore because the 727 is so ubiquitous, but if you're not going for big horsepower a stock 904 will work just as fine, if not better thanks to be lighter and having less internal resistance.

MrOnBicycle posted:Found a bit of an "oof" when pulling off the exhaust manifold: Welding cast iron is a bitch. To do it correctly you need to pre-heat the whole manifold since cast iron isn't very ductile, it cracks easily due to thermal stresses when rapidly heated or cooled. If you do it incorrectly the carbon (cast iron has a high carbon content) might also migrate into the weld and cause it to become very brittle and crack. Cheap headers can be had for under 3000 kr, otherwise I'd try finding a professional to weld that. Which will probably be more than 3tkr.
