Great thread, are you going to pull the heads?

Interesting to see how the Pontiac V8 developed. The 62 I rebuilt still had that 4 bolt water pump and that crazy cork front seal but the timing cover was aluminum not cast iron and no reverse flow heads of course. Also had the hinged oil pump pick up. There was a dished piston version available that would allow for a regular gas 389. Mine was the venerable 4bbl 10.25:1 303hp version, great production engine.

BR's,

Mark

It's looking like I will be yanking the heads pretty soon. Cleaning the carbon off the pistons and just generally cleaning up the heads needs to be done. I also have a better set of valve springs that I took off of some '64 GTO heads that I want to use.

Do this in case you ever mount a belt-driven accessory (A/C compressor in my case) outboard of the passenger's side valve cover. If you don't cut the tab off the V belt going from the crank pulley to the A/C compressor will hit the tab.

Thanks for the tip Bill.

You might be able to contact an industrial bearing company for a modern timing cover seal, just need measurements...

I have a few new timing cover seals here already, I'll ask a friend who has a Bridgeport mill handy to help out with boring out the front cover to accept a seal.
