I have a P79 head for sale. What condition is your N42 in? Maybe we can work out a deal. Shoot me an email to discuss further.

Ok, those splines are a challenge to count and I swear I counted 29 of them...I even counted a second time. Does that make any sense?

Ok, so now I'm honestly feeling like a complete idiot...I can not seem to determine if it's a 4 or 5 speed, I'm only able to confirm 4 shift positions which I know is wrong since a 4 speed would still have 5 positions with reverse! Below are the pix, hope they help.

How do I tell if it's a 4 or 5 speed all by myself? Just kidding, I can get that far of course...it's determining which of the various flavors it is after that point. I'll put a stick in it and run it through the gears to see if it's a 4 or 5 speed. I should have done this before posting, my bad. While out doing that I'll shoot a pic or two of it also. I would never! Oh, and thanx for the help.....Shirlye.

# of splines, perfect! Thank you John, that's exactly the kind of information I needed. I may have to shoot a pic when I dig out the rear suspension section (it's all assembled still) to help identify it better.

Is there a way to visually tell if the rear suspention parts and stub axles are from a 240Z or 280Z or 280ZX and from an R180 or R200? I have some rear suspension parts that I'm needing to identify.

Yes, I was there Tuesday for the car show...here's a link to the pix I took: http://www.pape.ws/gallery/v/Our_Life_Together/Our+Hobbies/Allan_s+Hobbies/240Z+Car/2009+ZCON+-+San+Antonio/

If you want a stock Z oil pan I have one for sale, please shoot me an email if you are interested.

Really? I can't believe there's been no replies to this...

Are you talking about the part that is under the cowl cover? I've got one of those for sale, check out my website for pix and price www.TexasZ.net and shoot me an email if you are interested in it.

Ok, I've searched and found some good yet slightly confusing information about identifying your transmission. On the one hand ZHome seems to indicate that I have the B type 4speed as shown here: http://www2.zhome.com:81/ZCMnL/tech/69-83TrannyShifterDrawing.jpg Then on the other hand this page seems to indicate that it could be either the B type 4speed or wide ratio 5speed: http://www.gracieland.org/cars/techtalk/gearing2.html Is there a better, more definitive way to determine which transmission you have since these two sources which are both referenced several times on this site seem to be inconsistent?

Perfect, thank you!! That's what I thought, just wanted to confirm.

Ok, I know it's on this site somewhere and I've been searching for about 20 minutes and still can not find it! Using the numbers stamped on the ring gear how do you calculate the ratio? Do you just divide the two numbers such as: 39-10 = 3.9 37-11 = 3.36

Thank you for the info, it will help! Yes, the 3.9 R180 is quite rare and it took a while of searching to locate mine. As it turns out it was pulled from the truck when it was only a couple years old because it was totalled and had sat on the shelf in the junk yard ever since. Got a screamin' deal on it too because the guy at the yard didn't think anyone would ever buy it! I had done tons of research a few years back on diffs and tranny ratios and settled on this combination. That's not to say I may not want to change it. As for the seals and bearings, the shops I contacted (even some that are very acquanted with Z cars) none would touch it. Locally all roads dead ended except for the dealership. The other shops didn't want to take it apart and attempt putting it back together again due to the aformentioned tollerances. *shrug*

Jon, There's a 5-speed in the car now though I don't know which one. I have a '77 5-speed and an R180 with 3.9 gears to install. The tranny has already been gone through...I just can't find anyone willing to touch the diff and replace the bearings and seals due to the extrememly tight tollarances Datsun/Nissan has on it...the only place I found was the dealership and we all know how their prices are. This is another story though. I'm going to use triple Mikuni 44s on the engine (already got them from Wolf Creek a while back).

Thank you for the added input Mike. Jon, no I didn't drive it...the head is off the car and is what I'm looking at buying. So I've never driven nor even heard a car run with this head/cam. The seller just said "that is was peaky and made most power above 4000 rpm. When the power came on, it really pulled. It idled rough, like a cammed V8. " Now if this is true I'm not sure that's a good fit, making most of the power above 4k seems pretty high to me. ARGH!

Jon, I've done a bit more research and calling on this and agree it does appear to be the Stage IV Schneider cam from MSA (I can't remember if the seller said it's an Isky or Schneider). Anyhow, I just called MSA and the guy said that he'd really recommend the Stage II instead citing that the Stage IV power band is 3500-7000. This seems pretty darn high to me! Sounds like no power off the line unless you are rev'd up over 3500RPM and then you're likely spinning the tires instead of putting it to the ground. Any experience/input on this? Car use will be to autox, maybe road race (a buddy has been enjoying a track he recently found more than autox so I may give that a shot), and some street use (not a daily driver).

Will the classicz group have their own corner to hang out in? It would be cool if that could happen...

Jon, thank you for the info...that helps a lot!! This is exactly the kind of info I was after. Now if I apply that info to a stroker bottom end you'd be in good shape it seems since with this cam you are giving up some torque it's no big deal because the stroker has so torque already.

Cool video, wish I could download it.

Just curious if anyone on here is planning on going to ZCON in San Antonio at the end of September? http://www.zcon09.com/

That fits...they reminded me a lot of the Enki 82 style. I remember in the late '80s I wanted a set of Enki 82 for my Accord I had. Thank you Arne for confirming my suspisions about these wheels.

Medium sized cam being good for top end or low end power? I really don't know much about cams if you can't already tell that.

I have a set of wheels with R.E.I. cast in the back so I went searching the web and turned up nothing. Can anyone help identify these wheels?

There's a guy locally selling a ported & polished N42 head with these cam specs: 495 lift with 290 duration I think it was 107 lobe seperation. Only pulled about 9 or 10 inches of vac. at 1000 rpm. Pulled like a bitch in heat after 3000 or so rpm. That head made 191HP to the wheels on a stock bore flat top bottom end with a header and standalone efi. What does this mean in laymans terms?
