What is the stock ride height of a 240Z? My Z is 27" at the front wheel well fender lip and 26" at the back (measured through the center line of the wheel). I am not sure if this is due to spring sag in the back or the pressure of the new Tokico gas struts in the front. At any rate, I have totally redone the suspension sans springs. I have also just mounted 16x7 Panasports with Kuhmo 205/55/16's and in that 26" back wheel well they are perfect so I only want to lower the front 1" not the back. Any thoughts?

I have a '72 240 in close to perfect condition. It has 69,000 miles and I have redone the entire suspension (bearings, 4 piston calipers, new wheel cylinders, poly bushings, tokico shocks etc. etc.) So now that I have a decent suspension and braking system, I am interested to know what can reasonably be done with an L24. I am considering conversion to HEI electronic ignition (have the parts), a header and 2-1/2 inch exhaust and maybe a cam. But, again -- what can I reasonably do to this car? By reasonably I mean without sacrificing drivablity. What kind of power can I get from an L24 and what is the best way to go about getting it. The car is a toy and not used as a daily driver -- however, it is driven on the street. Any suggestions would be very much appreciated. P.S. I have considered a V8 conversion but do not have the heart -- don't need the tickets either.

I am getting the parts together to do the GM HEI electronic ignition conversion to my '72 240. I bought a '75 280Z distributor but turns out it was from an automatic and has two reluctor pickups. Apparently the second pickup is to retard the timing on if a temperature switch (on the 280Z) is closed. I disassembled this thing, cleaned and lubricated it and put it back together with only one pickup. I hooked it to an oscilloscope and the signal appears the same as before dissassembly. Any reason why I just can't remove this extra pickup? Also, there is a part called out as a "contactor" that I put back in but am unsure of how to set the gap. The contactor seems to come into contact with the shaft under the reluctor -- am unsure of it's function since it is electrically isolated from the rest of the circuitry - unless it is to ground the shaft during spark discharge. Anyone know anything about how to set the contactor gap? Finally, with respect to the GM HEI module. I read that it is reliable and that it is prone to overheating. Does anyone have any experience with this and or another ignition module that they have had success with? Any help would be greatly appreciated.

I have a '72 and I have rebuilt the entire suspension -- new poly bushings, shocks, bearings, wheel cylinders, Toyota 4 piston calipers etc. and I still have noise from the rear end. It is similar to yours -- it is a zzzzzzzzz (mid to high pitched) that increases with speed but stops when I let go of the accelerator pedal. I also still get a little klunk even though my differential, tranny and motor mounts are new. The gears in the differential did not "look" worn but I did not investigate further. I too may be going to an R200/280ZX 5-speed setup. Not much help but misery loves company.
