    Just bought a 521

    Man, air hammers are awesome. I bought a special 8mm tool for it, heated up the head a little bit, and had all the old guides out in 10 minutes.
  2. Hmmm, now I gotta take a look at the one that I got with my short block. I wanted to lighten it a little bit, but it may already be the lighter one.
  3. You sure the flywheel is heavier? The 200 and 225 was only the clutch diameter, but the OD of the flywheel is the same.

    1971 Datsun 521

    Yes, custom. They said prior to Covid, turn around time was 2 weeks or less.

    Tell you what, covid has been disrupting the supply of nearly everything. I wouldn’t be surprised if there was a shortage of spark plugs or some other BS. I went to get a piece of tempered glass ordered yesterday, and they told me it was going to take 6 weeks!

    Well, it’s going on this L20b, so I guess it makes sense. Not sure what year it’s from.

    Just bought a 521

    Sadly, no. It’s a “NISSAN OHC” cover.

    Just won a NOS valve cover on eBay for $25!

    I did the initial setup of this class A amplifier in the engineering lab at work.

    I think you’ll be fine running projected in a stock engine, and the resistors don’t make that much difference, so if BPR6ES is all you can get, just use them.

    Yes, but one who believes in practicality and data-backed science. I won’t go spend a $1000 on some oxygen free copper cables with magic boxes in the middle of them. There’s a lot of snake oil in the industry, and unfortunately, a lot of people buy into it.

    My 1971 521

    I just filled my new pump with oil, but I didn't take the rest of the engine apart. If I were you, I would fill it, and then prime with with the above method. If you end up modifying one of the drives, just keep it in your "Datsun tools" bag. We all have one.

    Not if they're facing different directions. Think about it: the driver's side door speaker is firing into your leg and bouncing off the wall on the other side of the cab. Your head is completely out of the zone that the mid-woofer is projecting to. Not to mention...this is a 521, not a bus. Then again, I don't know much about audio.
