    He says that he has an HEI distributor.

    The Holley Street Avenger uses vacuum secondaries which can be adjusted using their secondary spring kit. Let us know how it works out.

    Your car sounds good otherwise. You are not running a big engine so the mechanical fuel pump should be ok. I know the Edelbrock tuning guide well. I tried a variety of jet and metering rod combinations without any improvement. Another problem I had with every Edelbrock carb was stalling under hard braking or cornering. It is a float thing. I finally concluded that I could use the Edelbrock carb as boat anchor and replaced it with Holley Street Avenger five years ago. Did one dyno run and haven't had any issues since. Please post how you resolve this.

    What have you checked so far? Check the basics: fuel pressure, float settings, jets, metering rods, advance etc. If the problem exists after diagnosing the usual things consider: I had a similar problem using Edelbrock 650 cfm carbs on two SBC 350 240Z projects. After wasting a lot of time and money "tuning" the Edelbrock carbs, I switched to Holley Street Avenger carbs and the engines no longer boged plus the off-idle throttle response was excellent. The difference between Edelbrock and Holley was night and day. Out of the box the only thing I did with the Holley was to use stiffer springs to delay the onset of the secondaries.

    That master cylinder is a "fast fill" or "step bore" master cylinder designed to work with "low drag" brake calipers. Fast fill calipers have a seal that withdraws the piston further back in the caliper bore so the pads do not ride on the rotor hence they are "low drag". That bulge on the side of the master cylinder contains valving to work with the step bore piston which provides an extra volume of fluid at the beginning of the stroke to make the low drag caliper piston move out of its resting position to push the pads into contact with the rotor. After the initial push of fluid, the master cylinder works like any other master cylinder. If you have a car that doesn't have "low drag" calipers and you install a fast fill master cylinder you would experience a higher, but stiffer, pedal. However, if you have installed disk brakes and a larger master cylinder and still have a long pedal this might be a solution to reduce pedal travel. I haven't seen anyone try this.

    You will need to consult the factory service manual (FSM). Look in the downloads forum for Xenon where you can find a pdf of your specific FSM.

    So is your car a Honda, 240Z, 280Z. 280ZX, 300Zx or should we guess????

    All of that JB weld will have to be wire brushed off and you will have remove the barb on the end of the tube. The use of the compression fitting requires that the tube be smooth, clean, free of burrs and bends etc. or it will not slip over the tube - very close fit. I used some fine emery cloth to prepare the tubing for the compression fitting. Since the the tube requires re-brazing, just pull the tank and have a -6 AN bung installed and braze the original tube closed. Clean up the tank and install a new sending unit while the tank is out. Or do as RB26power suggested. Recommend that you search more gas tank issues in HybridZ before doing anything.

    Look at a schematic, other circuits run through the headlight switch as well. Note from the schematic that the headlight switch also switches on other circuits such as the tail lights, dash lights, running lights, parking lights etc. The contacts for those circuits can be dirty or distorted such that no contact is made. Those contacts can be repaired. Over the years I learned that whenever the lights mentioned in this thread were out I found the headlight switch to be bad. So I keep a set of working turn signal and headlight switches around to use when diagnosing light problems. It takes but a few minutes to swap in a known working headlight switch. If it works you are done. If it doesn't work then you have just eliminated a variable in diagnosing the light problem and can move on to the next step. Or you can use a schematic and volt meter to check each contact on the switch.

    Check the headlight switch. Fast check is to replace the switch with one you know works. Or you can learn to check the switch wire by wire with a meter.

    Some good info at Zcar.com: http://www.zcar.com/forum/10-70-83-tech-discussion-forum/122943-78-280z-heater-valve-photo.html Lost of threads about the 280Z heater at Zcar.com.

    After reading your other posts, and your replies to attempts to help you, I have come to the conclusion that you are playing games.

    How can anyone help you when you don't know the names of the components you are testing or proper testing procedures? By reading the FSM you will have the correct terminology to more clearly explain your problem which is more likely to elicit helpful responses. You will also become a better mechanic. The FSM may even have the exact solution to your problem!

    Just install an Earls 5/16" to -6 AN compression fitting on the original outlet tube. This fitting allows interfacing a -6 AN line with tubing. I used these to go from the tank to the fuel pump, from the fuel pump to the original hard line going to the engine bay and from the hard line near the inner fender to a -6 AN line to the carb. http://pitstopusa.com/b-4636-133905-earls-performance-products.html

    What about the gap between the hood and the cowl? Will the gap still be there?

    Some Eibach problems came up from other Z sites when I Google "eibach 6305.001"

    Your car is a 240Z or 260Z? I recalled seeing a post on classiczcars.com Hope this helps: http://www.classiczcars.com/topic/38373-240z-eibach-springs-in-260z/

    From your original post: The 4 piston caliper: The Toyota 4 wheel drive pickup trucks from about 79-85 will bolt directly onto the Z strut and will work just fine with the stock non vented rotor. This upgrade will require the minor step of trimming the backing plate to make room for the new larger caliper. It is also recommended that the larger 79-81 280ZX master cylinder be used, since the 4 piston calipers displace quite a bit more fluid. Although the master cylinder isn't absolutely necessary, the pedal throw is a bit long without it. Fits most 14" rims.

    Why do you need a 15/16 MBC? If you have stock brakes the 15/16 MBC will increase the brake pedal force required to stop the car. That is, your car will not stop well. Recommend that you research the 15/16 MBC swap and the brake line issue before doing anything. There has been a lot written about this subject in the brake section.

    Suggestions: If doing a V8 swap buy the JTR book and read it at least 5 times. Buy a FSM and Haynes repair manuals for your specific car. Download electrical schematics for your car. PDFs are easier to read than those found in books. Buy the book How to Restore Your Dasun Z Car by Wick Humble. It will save you hours of searching. Focus on searching Hybridz for at least 40 hours as 99% of your questions have already been addressed. Make a detailed plan with parts list including cost. Start bookmarking Z car parts suppliers - there are many! Remember these are 40 year old cars and will need restoration to be safe and drivable. Join Classic Z Cars website and search there as well. Become well informed about modifications before asking questions. People will be more inclined to answer informed questions as apposed to the I am too lazy to read/study questions. Have some money. I stopped counting after $12k. Read all of the new member FAQs. Read, study, plan, execute the plan.
