My 71 had 175/70 14". The speedo was very accurate with that tire size. It was 2 years old and had Bridgestone tires on it when I bought it. I think they were the original tires.

You bring up an interesting point. The finish will change the appearance of the color. I wonder if the original blue paint was satin or matte finish. That could explain the difficulty matching the color. I don't remember a gloss finish on my original Zs' engine, but it was 2 years old when I got it.

I had a 71 Datsun PU with a rough distributor cam that used to scrub material off of the cam follower on the points set that narrowed the gap. Worse yet, it was a dual point dist. I was adjusting points about every 3 months. I dab of grease on the cam may help if it is dry.

Interesting. When I bought my first Z in 1973 (a used 71), it came with a crunchy trans. No bearing noise, just crunchy shifts. Drove it about a year before tearing it down to replace the synchros and bearings. When I got it apart everything was pristine.??? Synchros looked new. Having new parts on hand (OEM) I reassembled the trans. using the new parts. Problem solved. I have never known what was wrong with the original synchros. Now I suspect it could have been a change of gear oil (different brand?) that cured the crunchy shifts. I drove the car another 20 years and never had synchro problems again. I did refresh the trans, years later for bearings. I'm curious, was there a great difference in gear oil back then? I likely used Kendall gear oil as the replacement.

I believe they fall into the "Coat of Arms" category. Middle ages till now, they are still in use.

Great advice from the members. Personally, I would try to buy the car at a reduced price. One has to assume the engine is toast & won't turn over or is making a horrible noise. If it truly is a COMPLETE CAR & IN GOOD SHAPE, the engine wouldn't be a deal breaker for me. In fact, it might be a deal maker. There are plenty of good used engines still avail.

Virtual exhaust notes! Good Grief. So next I can upgrade my audio in my 4 cyl. daily driver to sound like a big block V8. Or maybe a 12 cyl. Ferrari, Yeah that's it. Oh yeah and some big a$$ speakers so everyone around me can hear it too. Good Grief.

Concerning the hot start issue. Has anyone tried spraying the injectors, lines, etc. with something cold such as pressurized propane or CO2(better option) to condense the fuel? In theory it seems as if this would be a good way to get going without the wait.

Fuel tank, lines & filters!!!

"He and I have discussed mechanized ways to vibrate the pot but haven't implemented anything yet." Suggestions anyone?

Good job. It's always a great feeling when one figures "it" out. "The thrill of victory".

Dennis, I remember being buffeted around sideways on I-5 but nothing that pushed me more than 2-3 ft. Wind socks on the freeway? That must be a tough stretch of road. I haven't seen the weather improving the last few years so the socks are probably in use or blown away. Cliff, Yes they do lift at high speed. In the past instead of replacing the arms, I squeezed the clip (hog ring) that anchors the bottom of the spring. I have also seen small wind deflectors(think venetian blind) that mount on the blades.

Normal oil level, both carbs. Do the pistons drop at the same rate? If not try swapping either the pistons or the chambers & try again. If you need to really get into the details of matching the carbs,(no they aren't identical) get the ZTherapy DVD "Just SUs". Best money you can spend this side of a Uni-syn.

At WOT under a load, when it craps out, pull the choke a bit (richen the mixture) & see if it improves. If it does, you have enough of fuel in the bowls. If it doesn't, I would say it is fuel starvation. This is assuming the float level (critical) is correct.

I can confirm the 120+. Bone stock, early 71 Z on the PIR track. Speedo read 124mph. Probably off by a little but the speedo was accurate at 60mph. At that speed it felt like air resistance was the limiting factor, not the engine. I also remember how the front would try to lift if you were driving into the wind. No air dam or spoiler on the car. Lots of fun until it lifted going into a high speed corner. The fun turned into an agricultural racing "Big Moment". In retrospect that made it even more fun.

"I recommend drinking the stuff" I found it interesting that the symptoms of ingesting too much zinc are identical to those of fume fever. If you've ever burned or welded anything covered in zinc (galvanized) without adequate ventilation, it doesn't take long for the symptoms to appear.

I'll bet they submerge it in alcohol to induce the amnesia. Works on humans too.

I would guess, he's about to get very busy. I can hear the wheels turning in the Captains' head or is it from the collective minds from the readers anywhere remotely near PA.

I agree with John. A good frame shop can assess the damage & determine if it's worth repairing. Years ago I loaned my Z to a good friend who promptly ran it head first into a curb when he didn't make a corner. The entire nose of the car was drooping a couple of inches & the insurance totaled it. Fortunately, a fellow sports car buff ran a body shop here in Portland & he repaired it. I drove the car another 15 years with no problems. Thanks Ted. Should you decide to repair it, will you have to fix your marriage too?

That's an excellent question. Unfortunately, I don't recall the documentary covering that aspect. They did show a car body panel that had substantial damage, repair itself in a sub zero temperature. I wonder if you dropped the temp. too far, you wouldn't end up with a flat sided flat topped vehicle resembling the Cube.

Soo glad I was wrong. Good job finding it. I likely would have started tearing things apart only to confirm nothing was wrong & have to keep searching.

I watched a documentary about these new alloys. Many different options are being investigated. Some will recover with heat or cold. I can imagine body shops having a drive-in freezer to straighten sheet metal or park your damaged ride until winter. Self healing crumple zones. I doubt we'll see this in cars anytime soon. Maybe NASCAR could lead the way. It would make interesting pit stops.

I soo hope I'm wrong but this sounds like an internal engine problem to me. Flywheels & starters tend to make more of a scraping sound which may or may not be intermittent. I wouldn't crank it with the starter until I pulled the valve cover & visually check out the valve train. Can't see anything wrong? Put a long plastic soda straw into each plug hole & carefully rotate the engine to TDC #1 cyl. compression stroke & check the cam timing. Watch the valves & straws while turning the engine & you may see the reason for the resistance.

If you can give a detailed description of what you don't like about your ride & what you did like about the other, I think the members can give you a lot of ideas that can improve your ride & everyone has an opinion or experience they want to share. There are many combinations of springs, shocks & sway bars & they are bolt-in.

First things first. I need to patch the battery size hole in the f. well before the b. tray goes in anyway. The damage is quite easy to imagine. Picture a hole below the battery that is about battery size & extends to about three inches from the frame rail. I can repair or replace the decrepit remains of the tray itself.
