Motorsports Auto Sales or MSA has the best selection of headers and exhaust to the rear in my opinion. I have their 6to1 ceramic coated header and 2.5" premium exhaust on both my Zs and couldn't be happier. Anything '77 and above will be diamond shaped exhaust ports. The ceramic headers really bring the under hood temp down compared to the stock cast iron manifold. My 280 needed a 20" resonator for a bad drone sound on the interstate, about 70mph. Cost me $20 at my local muffler shop I believe. That's cut into and welded on too. The 2.4 240 didn't have that annoying sound though.

My guy put the same size seats which happened to be readily available. I had to lap them in myself and that's no nig deal plus actually what you want to do to get a good seal. Talk to your machinest. Make sure he's 50 or 60 at least and knows the L head. My guy has forgotten he claims but did a great job. Said he'd done 100s back in the day. You should also consider the spray bar on the older heads. I run a newer turbo oil pump on mine and it floods the valve train. That's what you want too. Does your e31 cam have holes in the lobe? It shouldn't but could've been upgraded to an oiler cam. Those e31 need to be researched as best as you can. They are old and many mods have been done since '70. Good luck with it, they're scarce as hens teeth kinda of a holy grail for our Zs.

I sure wish there was! I read for hours before I figured mine out but it was worth it. Maybe the block off plate and gasket? But there's a lot more to it than that if you do the hole $^!# and kaboodle.

My e31 had steel seats installed and my guy said they were common size, the Chrysler Hemi uses the same size. Mallory is the brand. It's not expensive to do so I would say do it while you're at that stage.

I'm in the "if they want..." group. Repo guys can get anyting. So with their knowledge and equipment anybodies stuff is steal-able. To add, my car lives in a garage and is never left alone at car shows, isn't parked as a normal car. My Camry is my DD. The only thing more important is my dog.

Yeah, look at our millitary, they'll take anybody over 18 and pass a physical. I do beleive in the 10% theory but the other 90% seems to set us up for failure.

Headers and an N42 intake off a '75 or '76. Pre EGR.

I agree with you on the free money for the young folks but I've had about 25% taken out of my pay for over 30 years. I pay for public education but haven't any kids. My next door neighbors home school their kids and get some kind of tax refund. I do not get that refund money even though I have no kids. Life sucks then we die they say. Bring it on!

I just caught that. Thanks!

The grinder and their number should be on the front of the cam where the chain sprocket is.

Just posted mine in another thread, good timing!

My Schneider. 460 lift which is considered a "stage 3" on MSA's website has the same cold adjustment numbers as factory specs, intake .008 and exhaust. 010.

Okay I'm a pervert, I'll admit that but I apologize for going to the dark side after reading the above. Would someone please agree with me? Steve is my hero and I don't wish to upset him.

Boy oh boy! That's NSFW (almost). I must congratulate you on walking the wire, tip toeing around there. Excellent job Steve!

That's absolutely true. My fuel rail is cool to the touch. I consider it an open system. I used a '78 fpr with one in and one out. It constantly flows fuel.

Here's what I did for about $50. The end of the job...

You're asking us with all that experience? We need you!

I'll add don't overthink or get intimidated, just get a good plan after researching the previous posts. It's really easy. I did my 1st one by myself after reading this book. It's the Z Bible if you ask me. https://www.amazon.com/Rebuild-Nissan-Datsun-Engine-Publisher/dp/B004X9A0OA

Set some time aside and read. It's been gone over many times and you will learn the tricks/shortcuts. Very easy with the right preparations. https://www.google.com/search?q=280z+engine+removal+classiczcars.com+&client=ms-android-americamovil-us-revc&source=android-home&source=hp&ei=WpdPYdLgGsKygge18KiwCQ&oq=280z+engine+removal+classiczcars.com+&gs_lcp=ChFtb2JpbGUtZ3dzLXdpei1ocBADMgUIIRCgATIFCCEQoAEyBQghEKsCMgUIIRCrAjIFCCEQqwI6AggpOgUIKRCgAToECCkQRzoFCCkQgAQ6BwgpEAoQoAE6BggpEBYQHjoECCkQCjoNCCkQxwEQrwEQDRCTAjoOCAAQ6gIQjwEQjAMQ5QI6BQgAEIAEOgsILhCABBCxAxCDAToICC4QgAQQsQM6DgguEIAEELEDEMcBENEDOgsILhCxAxDHARCjAjoLCAAQgAQQsQMQgwE6CAgAEIAEELEDOgsILhCABBCxAxCTAjoLCC4QgAQQxwEQrwE6BQgAELEDOggIABCxAxCDAToICAAQgAQQyQM6BQgAEJIDOgQIABANOgcIABDJAxANOgYIABAWEB46CAghEBYQHRAeOgUIABCGA1CULljI3AFg0OcBaAJwAHgAgAHFAYgBwx2SAQQwLjI2mAEAoAEBsAEe&sclient=mobile-gws-wiz-hp

Yes, pretty much narrows it down to the rear carburetor. I'm not sure if the SUs have an idle circuit but that's what it sounds like.

A quick google, I was looking for Tabco but they don't have anything. Good luck! https://www.google.com/search?q=datsun+280z+lower+radiator+support&client=ms-android-americamovil-us-revc&ei=OYZPYc-qGt2awbkPxYWoqAY&oq=datsun+280z+lower+rad&gs_lcp=ChNtb2JpbGUtZ3dzLXdpei1zZXJwEAEYATIFCCEQoAEyBQghEKABMgUIIRCgATIICCEQFhAdEB4yCAghEBYQHRAeOgQIABBHOgYIABAHEB46BQgAEM0COgQIABANOggIABANEAUQHjoFCAAQgAQ6BggAEAUQHjoICAAQBxAFEB46BAgeEAo6BwghEAoQoAE6BQghEKsCOgYIABAWEB5QlxRYu-YBYPj3AWgBcAF4AIAB0wGIAaEokgEGMi4zNi4xmAEAoAEByAEIwAEB&sclient=mobile-gws-wiz-serp

Those dopes that have TV shows for living in Alaska need a little covid. That's what I consider ironic. They go off grid and then have a production crew around all the time.

I've used futofab for parts simply because of the shipping prices. I live closer to the East coast so he saves me a good bit. But he has been very helpful as far as a gentleman that owns a business. I give him 5 stars! Would buy from him again.

There's 3 kinds of jobs in my experience. 1. Wash your after the restroom. 2. Wash your hands before the restroom. 3. Wash before AND after. I've always washed mine beforehand. That's because I hated school and wound up working in the service businesses. I'm a hands on type guy that gets a good feeling helping those that can't help themselves. The pay sucks but money has never been a priority in my life. My parents always gave me a good life and i loved them for that. I'm so thankful for you guys positive comments on my ife decision to go to less stress/less money. I do not care about money. I want to sleep good.
