  1. Victor Reinz is now repackaging Felpro gaskets. Just a heads up. I know a lot of companies have similar business practices, but this one was a bit disappointing.

    Yeah, either way works. I don't have a modified spindle, so I use the spark plug method. Removing the plugs prevents compression/suction so the engine spins over faster and gets the oil going. Just preference.

    Make sure it's primed. Pull the spark plugs and use the starter to spin the engine until you get oil everywhere. Keep it up off of idle for a while so that it can maintain a decent oil pressure. Technically that's more important to protect a new cam/rockers, but you'll want to make sure your new main and rod bearings are getting plenty of oil. Fill it up for the first time with conventional oil. Better for ring break-in, plus you'll be changing it fairly soon after break-in anyway.
  4. Pretty sure most Datsun steering hubs are the same. My ‘68 roadster hub fits my ‘71 hub no problem.

    Sure have. I watched all the vids of the twin turbo boat that Mike Finnegan recently built.

    I think you should humor us and run a giant flex pipe all the way to the back. Get some of that expanding metal dryer hose.
  7. DP I improved it. See above. No more glare on the windshield at night.
  8. Head is done. Went with .150’s on the exhaust and .180’s on the intake. Wipe pattern is right in the center. I don’t feel so bad about those 180’s now, since a lot more of them sits in the retainers.
  9. @banzai510(hainz)Lash pads showed up. They’re pretty nice. Metric sizes, but close enough. Come in .25mm (0.010”) increments like usual. Pocket on the bottom is exactly 2.0mm deep. I don’t know what the alloy is, but I can tell that they’re hardened and I’ll put one on the harness tester at work. Top is precision ground to the correct thickness and I measured a max variation of .01mm, which is less than my verniers can read anyway. Thicknesses are laser marked on the OD for quick reference.

    Firing order is always the same counterclockwise 1-3-4-2 and you’ll have to remove the spark plug wires and re-plug them because it’ll turn the cap.

    Sorry, I was wrong. Mine is how you originally said. I did have to widen the slots in the plate to allow for a little more adjustment. I basically rigged mine together to get the matchbox away from the exhaust a little bit, and still have the timing line up.

    Are you running a matchbox dizzy? Use the mount on the far right, but the bolt hole faces the radiator, so flip it 180 degrees. If I remember right, I had to flip the thin plate over as well.

    The post on the starter. The battery also has a big red wire that goes to the same post.

    His is a later one, you can tell by the case.
