Sounds like the car is pigeon toed so that going forward tends to push the tires inward where going backwards tends to pull them apart.

I guess there were a couple of install options that different dealers used for installing A/C. My series I car had the dealer York compressor installed on the same side as Tom's. I removed the York and installed a Sanden down where the air pump used to be (haven't completed putting it back together yet though). When I did the 3 row radiator with electric fans it wouldn't fit with the York so I had to remove it and go with the low Sanden mount. Old compressor New Compressor

If straight lining works and you can't rely on correcting the oil pressure / AFM switching you could just go with an inertia switch in your new straight line circuit to cut power in the event of an accident.

You could always make your own like AK260

Found the Float Sync's here; http://www.2040-parts.com/datsun-240z-su-carburetor-float-sync-tool-i1994669/

I thought all the 240's stock antenna's had the pointy tip. At least both my 73 and early 71 (build date 12/70) had the pointy tip. My 71 now has an after-market replacement that I got from MSA back in 1991, but I don't think it's available anymore.

And what happened to the Chevelle? Was it a stick? Also a very sweet ride!

I also did the new seat foam and I'm about 5'9". I too noticed that I was higher in the seat by maybe 1 to 1.5 inches. Definitely noticeable, but I kinda like being a little higher. ?

Is it the fuel gauge sender? Once upon a time I had my tank out to clean, paint and seal. When I put the tank back in I buried the sender unit wires between the tank and the car. Had to lower the tank to pull the wires for the sender out.

Yes, the round tops have a heat shield between the exhaust manifold and the carbs. You can see the heat shield in this shot

I'm guessing that with too much advance on the spark you get the firing happen during the compression stroke which pushes the piston in the opposite direction of travel which may damage pistons, rings or other bottom end components

I'm thinking of all new suspension rubber, strut bearings and the Koni's with stock springs. Found the OEM insulators for the $64.21 on Amazon with free shipping which makes the price difference from after market only about $40! https://www.amazon.com/1970-1978-Nissan-Front-Insulator-54320-E4100/dp/B00TNL7LTK

This part # does not show up on https://parts.nissanusa.com/ Where were you looking?

So nobody has an opinion or knows anything about the $48.00 strut mount insulators?

I thought the taller ones were a 280Z thing. https://zcardepot.com/products/upper-strut-mount-spacer-240z-260z-280z?variant=19280977494129 The rear spacers for a 240Z are only $11.00 for the pair https://www.thezstore.com/page/TZS/PROD/classic20h06/23-4166 so they will match the the size of the upper front bearings https://www.thezstore.com/page/TZS/PROD/classic20h06/23-4376

I'm getting ready to go through the suspension on my 71 240Z. I find that OEM strut mount insulators are ~$80.00 https://zcardepot.com/products/strut-mount-upper-insulator-front-rear-oem-240z-260z-280z and after market @ ZCarDepot are $48.00. https://zcardepot.com/products/strut-mount-upper-insulator-front-rear-oem-240z-260z-280z-1 Anybody have experience with the after market ones. The saving on all 4 is like $120.00 for the aftermarket.

Glad the kids are okay! The car doesn't look beyond repair.

Why not just use an inertia switch to cut power to the pump in a crash. https://www.amazon.com/Ford-5L2Z-9341-Genuine-5L2z9341a-Inertia/dp/B000NTI03C/ref=sr_1_2?keywords=ford+inertia+switch&qid=1558051529&s=automotive&sr=1-2

Thanks to both for the replies re: high altitude!

I wonder how much effect altitude has on all this? Those of us in the Rocky Mountain region of the USA are typically at 4,400 elevation or higher.

On my 240Z I had interference with the thermostat housing too. I ground a little off the thermostat housing flange.

I had only heard of torque steer on front wheel drive cars. Did they do a full alignment after all the suspension work?

Thanks, if you remember or find your receipt, please let me know! Thanks.

@jalexquijano Is the air filter box shown in the 1st post in this thread on your 240z? If so, where did you find it? Thanks, Wilkes

Finally found the thread! The picture is in a post by @siteunseen found here Hopefully he knows where that air filter box came from. I like it. Wilkes
