Thank you guys for the nice comments

Since I shortly will remove my transmission and give it away for repair, I am currently thinking what to do with my engine meanwhile. Once the transmission is out, I plan to take out the engine too so I can access it from all sides.

The engine is running fine, so no major problems. It's leaking oil on many places, and also needs a new painting, since the preowner sprayed it red Other than that I am not sure about how good the compression is:

I measured around 110 psi at cranking speed on all eight cylinders (warm engine, throttle fully open). I have the 287 engine with 2 barrel Carter carburetor, but I'm not sure if I have the version with 7,4:1 or 8:1 compression ratio.

The shop manual says it should be 135-145 psi compression, but I think this is the value for a new engine (?). So is this a good compression, or not...?


The absolute minimum I want to do is:
- clean it
- replace all gaskets (maybe including cylinder head gaskets)
- paint the engine in the original color


What would be recommended to do too, once the engine is out? Are there any weaknesses this engine has, I should take care about?

What I am thinking about doing optional, but I have no idea if really neccessary:
- replace the timing chain
- Regrind the valves (would improve compression)
- Resurfacing the cylinder heads
- cylinder honing
- new piston rings (would improve compression)
- check all bearing clearances

I checked Kanter Auto, they have almost all engine parts for rebuild. Also Cars LLC has the right gasket set: https://www.ebay.de/itm/174122853138
Ames has the most parts too. Any other classic part suppliers that can be recommended?
