SysAdmin & Mods- Not sure if this is a stupid question, but here goes... Do we need a new sub-forum in "Engine Components" titled 'Cooling' (or 'Cooling/Heating')? Seems like these types of questions get spread about in other, more general forums (e.g. "V8 Z Forums", "Misc Tech", and "Troubleshooting/General Engine"). Y'all may have already considered previously, but I'm just a dumb newcomer to HybridZ so I thought I'd ask the question. Thx! jhm

turbojohnny- Prelude seats work great in the S30. In fact, I think you'll find that Honda seats in general are well made, nicely designed, readily available at affordable prices, and have kind of a racey look (especially 90's era Hondas). I've got seats from a mid-90's Prelude in my '74 260 -- I paid $60 for them (including extra rails and brackets) and I love 'em. You can check out the pix in my post in the "Seat Swap" thread. The late-80's/early-90's Prelude seats look alot like Recaros, but they're hard to find in decent condition. Del Sol seats are really nice -- they look like Corbeau knock-offs, and are really narrow (a plus when installing in 260's or 280's with the catalytic converter hump in the trans tunnel). And believe it or not, but alot of Civics were equipped with comfortable and stylish seats. Good luck. HB280ZT- If you haven't already, check out tec280ZX's Celica seats in the "Seat Swap" thread. They were my second choice when putting in new seats, but couldn't find any in decent condition. They should work well with 5/6 point harness. r/jhm

JSM- You're absolutely correct. My bad...senior moment on my part. I've got a late '74 260Z, but I'm guessing that all Z's 1970-1978 may share the same (or similar) dust boot for the parking brake cable ends? I've checked all the usual suspects for parts (Z Car Source, MSA, Z Specialties, Datsun Restore, etc), and none carry said dust boots. I'll take new, used, or reman....mine have long since crumbled into dust. Thx again for catching the error in my WTB! r/John

Need the dust boots that cover the parking brake cable ends, where the cable links to the drum brakes at the rear wheels. Need two....one for each side. Thx! jhm "john.meyer12@us.army.mil"

CONGRATS on SNCOA! Make sure to take time out for the fun stuff, like weekends at P-cola.

Stony- Down at SOS, huh? Enjoy the free time and the opportunity to improve your golf handicap. Remember....it's only alot of reading if you do it! r/jhm

Soundmasterg- You may have solved your horn issue by now, but if not, you can easily bend the horn contact tab enough to provide good contact with the copper ring on the the Grant adapter hub. Use some dilithium grease (or any good lube compatible with electrical contacts) to ensure smooth movement between the two contact surfaces. Good luck and happy motoring. jhm

That's what I figured -- thx, Ryan. On a completely different subject, what kind of air dam are you using? Looks nice!

nullbound- Were those Hooker headers you were running with the Scarab setup, and if so, what model? They're obviously not standard block huggers....appear to be more of a shorty J-header. (Perhaps you did some custom fab work on a set of Hooker block huggers?) Thx for the reply! jhm

jt1- Actually, I only need to move the collector flange about a 1/2" inch inboard. I'm thinking that I should be able to do that without messing up the overall header geometry. Relocating the engine/tranny to a more rearward location is a possibility in the future, but for now I'm leaving it where it is. Thx for your reply. Again, open to suggestions on best way to tweak the header to clear the steering shaft. If anyone's had any experience tweaking ceramic-coated headers, I'd love to hear from you. jhm

Dan- Thx for your quick reply, and sorry for not providing sufficient info. The headers are generic SBC block huggers from KMJ: http://www.kmjent.com/cart/product.php?productid=563&cat=4210382&page=1 $164 (with free shipping) for ceramic-coated headers is hard to beat. I really don't think that the headers are the problem. I think my problem stems from the unconventional mounting position chosen by the previous owner that did the conversion -- the motor is actually an inch or two forward of a standard Scarab-type mount. You can see what I'm talking about from the attached pix. The pic that illustrates the clearance issue was taken from the floor looking up, from the rear looking forward. The passenger-side header fits fine. And I think the driver's-side header will also fit fine, provided I'm able to tweak it about 1/2" inboard closer to the block. Again, thx for your reply. jhm

For starters, you can check out "Creation Z" in Sterling. I've heard really good things about them from several guys. Don't know if V8 conversions are a "specialty" of theirs, but they do know Z cars inside and out. Good luck with your project!

Folks- Just bought some block huggers for my SBC 260Z, and I'm having clearance issues with the driver's side header -- there's insufficient clearance between the collector flange and the steering shaft. And yes, I've searched the forums, but could not find a discussion that answered my specific questions. It appears that I could solve my problem by making the header "hug" the block a little tighter. Does anyone have any tips or techniques for tweaking the headers inward (i.e. closer to the block)? Can I just heat 'em up and bend them inward with a big rod, or do I risk breaking the welds at the main flange? I should mention that they're ceramic-coated. I see two potential issues with this: 1) will the coating prevent me from heating them sufficiently to bend the headers tubes? 2) will I damage the ceramic coating if I slightly bend the tubes? Thx in advance for any assistance y'all can offer, and happy motoring. jhm

Even if your bumpers have been replaced, you should be able to determine which bumpers were there originally. The thin (early) bumpers had indentations in the front and rear corners to accommodate bumper mounting; the thick (late) bumpers had no such indentations.

janaka- The transition occured Aug/Sep 1974. Anything earlier is an "early" '74 and anything later is a "late" '74. I believe that the chassis number also indicates "early '74" vs "late '74". Anything up and including chassis # RLS30-060000 is an early 74; anything later is a late 74. Both pieces of information can be found on the metal body ID tag riveted to the inside of the driver's side door jamb. As rturbo pointed out, the turn signals are a dead giveaway for early vs late. The bumpers are another easily identifiable distinction. A good deal of Z-car historical and reference data can be found at the following website: http://www2.zhome.com:81/. Enjoy.... jhm

lovemstr- Happy to help. I recently did the tach mod myself, and still have some resistors leftover. PM me your mailing address and I'll send you a couple. jhm

DavyZ- Thx very much for your reply. I do not, in fact, have JTR mounts. The motor had already been installed when I bought the car -- one of the previous owners had done the conversion and it appears that he used some "el cheapo" homebuilt or other vendor's motor mounts. You are correct that they actually put the motor a couple inches further forward than the Scarab position. Not great for weight distribution, but sure makes it easy to work on the motor! Maybe someday when I'm feeling bored and masochistic, I'll relocate the motor. Thx again. jhm

Allen- If I understand your question correctly, you're asking if the right and left rear signals are wired independently.....correct? If so, yes, they are but they share a common ground wire. I can also send you the body electrical section from the service manual if you'd like -- will need your e-mail because the file's too large to post on this thread. jhm

cachanilla86- Check your PMs -- I'm going to e-mail you the "Body Electrical" chapter from a 280Z factory service manual. It's a great reference for tracking down electrical problems. Page 6 has sketches of the engine compartment relay block. Good luck and happy motoring. jhm

JDTIPPIT- I'm inclined to agree with jt1 that the high-mounts you're considering will not fit under a stock hood (but might fit under a scooped or cowl-induction hood). Have you checked Alan Grove brackets? They make a great selection of high, low, and mid-mount brackets for many applications. I'm using their low-mount alternator bracket (P.N. 206L-ALT, $65) on my Scarab-mount 1st gen SBC. It's a super clean setup that keeps the alternator down low and out of the way on the driver's side. See attached pic. WRT pulleys, I went same route as bjhines. Summit has good selection of decent aluminum pulleys at low prices. Good luck and happy motoring. jhm

hoov100- I couldn't use the Taurus fan because of interference between the fan motor assemby and the water pump pulley. I trimmed the fan's shroud as much as possible, but just couldn't get it to work with my setup. Went to the Spal fan and it fit fine. You can see from the pic that I have very little room between the radiator and the pump pulley (and that's with a short water pump). r/jhm

WTB: BRE front spoiler in decent condition, any color. Pls send pix and asking price to "john.meyer12@us.army.mil". Thx, and happy motoring. r/jhm

Gents- For what it's worth, I'd like to chime in on the new Post Count rule as well. I'll admit up front that I've only been a HybridZ member for a few months, but 40 posts does seem excessive. It's a shame that the new rules became a necessity. Obviously, I'll abide by the rules whatever they are. HybridZ is a great forum with a loyal following, and our Admins and Mods all do a great job on a seemingly impossible set of tasks. r/jhm

4A15- In case you're interested, I finally replaced my round carb-top air cleaner with a cold air system. No problems with hood clearance using the low profile air plenum. I plumbed it with 4" ducting and used a 9" cone filter mounted in front of the core support. Just another option for your consideration... JHM
