datsunfreak Posted June 27, 2022 Author Report Share Posted June 27, 2022 Also, of minor note, there seems to be some discrepancy on the flywheel bolts. Manual and auto bolts appear to be the same part number from Dodge, but a majority of the internet seems to think they are different. Also, the internet seems evenly divided about whether they should be reused at all. So... ARP makes some nice upgraded bolts for about the same price as OEM bolts... 2 Quote Link to comment
datzenmike Posted June 27, 2022 Report Share Posted June 27, 2022 Datsun are different too. Flex plates are thinner. Last thing you want is a too long bolt bottoming out. 1 Quote Link to comment

Yeah, we have ran into this on Datsuns before. Usually when doing a sex change on a Datsun you just throw the auto bolts in the bin. 1 Quote Link to comment

They do look a bit short, but I don't know what your old ones look like at all.. We compared them to the flywheel. They still look too short to me, but there will be 7/16" of thread engagement on a 7/16" diameter bolt. John preaches "One diameter's equivalant in thread engagement is the minimum" every time the "Hmm, that bolt/stud looks too short" issue arises. Also, this is what ARP says is the right bolt set for a Manuel transmission small block Dodge V8. So I'm not going to worry about it anymore.* Also also, we don't know how deep the holes in the crank are. This might be all the depth we have. Also also also, I do have a 12 point socket. *Which is to say, I'm totally going to worry about it until the end of time, of course. Edited June 30, 2022 by dimlight65 1 Quote Link to comment
datsunfreak Posted June 30, 2022 Author Report Share Posted June 30, 2022 New speedo came in... We took a look at fitting it in the dash, but didn't like mounting it out in front of the stock speedo because it kinda looked like butt. So I says to Tim I says, wonder how tough it is to just remove the speedo from the cluster? Got the gauge cluster out easily, removed the clear cover, and Tim set to work removing the stock speedo, which was surprisingly easy... New speedo seems to be a good depth for the cluster housing, but we need to make an intermediate piece (which you will see shortly), and possibly trim a few key spots on the back side for clearance... Should hopefully have that piece made before Saturday to reassemble it all and reinstall the cluster. 👍 1 1 Quote Link to comment

[Sorry to assume your gender but 1) I'm old and B) I'm from Texas] I think I told the story when we first got it low but, I remember the night we flipped the axle and took it off the jackstands for the first time. I eased the jack down and the rear bumper equivalent just kept going lower and lower! I just stood there and laughed. "I don't care if it is undriveable," I said to john. "We have to get the front that low!" Eventually, we did. Quote Link to comment

With the fine thread pitch, a dab of blue Loctite, and torqued to proper specs, I'd be doing 5k rpm clutch dumps and burnouts for days...😁 Edited July 1, 2022 by Duncan 1 1 Quote Link to comment

It comes with some sort of assembly lube you are supposed to use instead of loctite? I have personally never used Loctite on a flywheel, and (anecdotally) never seen one come loose. But will concede that it sounds like a good idea. Edited July 2, 2022 by datsunfreak 2 Quote Link to comment

But will concede that it sounds like a good idea. I watch a lot of Motortrend (formerly Velocity) shows, and I started noticing most of those shops were using blue loctite on the flywheel bolts. I've used the blue stuff before on other bolts, and it's not terribly difficult to remove them. The Red is another story. I had the motor out of my first yellow 1200 Coupe and did a clutch since it was there and accessible. Didn't use it on that and had no problems. I just figured why not with the wagon. Cheap insurance. I've never used any sealer or adhesive spray on a head gasket and never had any problems there, either. With or without, I'm sure it will be fine... 1 Quote Link to comment
datsunfreak Posted July 2, 2022 Author Report Share Posted July 2, 2022 I was sort of successful in debiggening the speedo hole in the cluster face, also decided some wrinkle finish black was in order... Test fit in the housing... Tim decided to get some LED lights for it in purple, so we had to dig out several of these blue bulb covers that are buried down inside the housing... We also got it up on stands, removed the driveshaft, removed the trans cooler and lines, removed the starter, removed the trans harness and kickdown cable, removed the doghouse and shifter cable, and about half the bolts holding the trans in. We had to stop there because 1) it's hot as balls, and B) we do not have the right socket for the crank pulley bolt. If you have ever removed an automatic, you know you have to be able to rotate the engine to get all the flywheel-to-torque converter bolts out. I got two out, but could not spin the engine over to get the other two out. We will also need it to be able to torque down the new flywheel. We should have that for next time, though. So as it stands, we are about 30 minutes from removing the autotragic for good... 😈 1 Quote Link to comment

dimlight65 Posted July 2, 2022 Report Share Posted July 2, 2022 (edited) I probably shouldn't post this until we have one more look at clearance issues but... There are two bolts per manifold on the zorst that are not clamping at all. The washer just spins free under the head of the bolt. So I'm thinking now is the time for: We have some header paint that we could bake on ourselves, but ~$90 for ceramic coating sounds... well, it sounds like a cheap-assed ceramic coat, now that I think about it. I don't know. We will grok the space available and come to the decision I have probably already made. Edited July 2, 2022 by dimlight65 Quote Link to comment
dimlight65 Posted July 3, 2022 Report Share Posted July 3, 2022 (edited) And screw it! These supposubly bolt right up to the stock zorst, and are half the price. I ordered a set. That's right, I said "supposubly." Edited July 3, 2022 by dimlight65 Quote Link to comment

EDM620 Posted July 3, 2022 Report Share Posted July 3, 2022 I never liked that about Mopar blocks. If you still have all the original bolts, some (all?) have a narrowed shoulder to reduce the water flow restriction. Not these ones apparently... Per MOPAR: Description: This Mopar manifold bolt (6510140AA) keeps the exhaust manifold of your vehicle in place. These exhaust manifold replacement bolts are three inches long and an inch wide, making the parts a perfect fit for your car. Your exhaust manifold is often exposed to extreme temperatures during operation. The part will expand as it quickly heats up, pressurizing the manifold bolts. The constant expansion and contraction of your manifolds can damage the bolts and fasteners over time. Quote While a loose or broken exhaust manifold bolt will not cause your antifreeze to leak into the oil, it can cause your manifold head to crack and start leaking . Change your loose manifold bolts to ensure the safety and optimal performance of your ride. Gee thanks Mopar. 1 Quote Link to comment
dimlight65 Posted July 3, 2022 Report Share Posted July 3, 2022 (edited) Well, EDM620 is not making me feel confident! But we'll move on and hope for the best until the worst occurs! Ok, I ran over to the shop to take a few pictures for y'all (It was hot as balls yesterday and we just forgot to take pix. Deal with it!) So... Van on stands Zorst removed Starter removed Trans cooler removed Doghouse w/shifter removed And driveshaft removed Then I had a look at the space between the doghouse and the zorst manifolds. The passenger side appears to be plenty spacious, but the driver's side is too tight for the Amazon headers. Therefore, I trekked over to Summit Racing and bought... Ceramic coated, block hugger headers! We're going to have to have that zorst reconfigured but, look at them! Edited July 3, 2022 by dimlight65 1 Quote Link to comment
