Here's a good read on what you're doing. You might read something helpful.

Is that Rick Springfield's brother?

Look between 1st and 2nd spark plugs to see what head you have. Should be an E88 or N42, maybe N47? That will tell us what exhaust port shape you have and whether or not you have the injector notches. If it's an E88 you can use the 240 gasket. Fel-Pro has a universal diamond shape exhaust manifold gasket but it has the injector notches too. From what I remember it will work with carbs but I've never used one so maybe someone can tell us? If it's the OE E88 I would use the right gasket with round intake holes and square exhaust ports. I bought mine through Nissan dealership but zcardepot.com has them too.

Well done! Congratulations from another OO.🎉

Hi: We are working on a family '74 260Z project, and finally about to pull the L28 engine with the cracked block out of the car and replace it with another L28. The donor engine had fuel injection, but we are going to replace it with the dual-SU carb setup from the old engine. Someone told me a while back to use a specific set of manifold gaskets in this swap, and I feel like they said it was from an earlier engine, but I have now lost that piece of advice and just wanting to hear from some of you folks who know better than me before I order anything. Check this short video? Thanks in advance! Michael Project Z ICT

Congrats and keep going! All the best to you and your "Z"

Put on your party hats and toot your horns. Join me in celebrating the 54th Anniversary of the day I bought my 1971 240Z. Today, it sits in my driveway proudly showing its age. Unfortunately, I'm also showing my age and have a little more trouble getting in and out of it and working the pedals than I did in 1971. Great car, great fun, 54 years of great road adventures!

Thanks Captain! This is more the info I was looking for. I guess I will be able to verify once my assortment of plugs arrive from Mcmaster.

👍

KYB is pretty specific about using no oil, but many people (including me) defy that recommendation and use some anyway. Since you aren't using the oil primarily for lubrication, but instead, more for rust prevention, I would recommend an R&O oil. That means "Rust and Oxidation". R&O oils have additives intended to minimize R&O. Here's a couple links for info: https://www.valvolineglobal.com/en/r-and-o-oils/ https://www.phillips66lubricants.com/product/multipurpose-r-o-oil-mining/

Do you have any more info for this? Where did you see it?

I believe that all the tapered fittings are BPT. Probably dictated by world manufacturing climate at the time. Some of the BPT and their respective NPT counterparts are different enough to easily tell the difference, and some of them are really similar. For example, with some thread sealant, it usually seals if you stuff a 1/8 NPT plug into a hole threaded for 1/8 BPT. But, I think the BPT is correct. There also does exist some locations where a straight thread was used (temp gauge sender unit for example), but I've found them to be straight up metric thread, not BSPP.

I offer two different versions of my conversion bell housings to do the reverse tilt. One for the CD009 and one for the TL70. Most of the people that buy my head end up tilting them so I offer the bell housings to assist in that.

I'm also planning on removing the water tubes that run through the intake manifold. Are these BSPT as well? I'll find out soon enough, I suppose.

Did you read my post?

You will be quite supposed on how easily the bspt plugs thread in. You will know right away.

Sean will want to talk to you personally wanting to know what you are working with before he ships you one of his headers.

Now THAT is the info. I was looking for! THANK-YOU!

Ok, I got the race-sport header and can confirm that it will not clear the oil pan with the heatshield. I of course learned this after the engine was in the car and was not about to remove it so I rolled up under the car with a Dremel and cutting wheel to cut the heatshield off. Once that was done the header fit just fine. Hope this helps keep you from being covered in sparks cutting the heat shield off after installation like I was. :)

You can get them for a 4-wheeler at your local motorcycle shop. They have those metal bands that work great instead of the e-bay ones that send you zip-ties.

I could have waited, much longer!

It will be interesting to see how the BaT S30.world/Garage 44 auction goes when it is (eventually) listed. Im guessing the 240-Z has been shipped to the USA to sell rather than be passed in.

Sounds good! Make a plan and stick to it.
