Ok thanks. I just got off the phone with the Accel tech department and found out a few things. The GM HEI Module (Accel 35361 and 35367) have NO RPM limit. The only difference is that the performance version (35367) that states a higher RPM range is due to the increased dwell. So a longer duration dwell is the only difference bewtween the two other than about $40.00 more. They stated that a Accel (8140) super stock coil is ok to use but recomemd a (8145C) coil since it is meant for point'less aplications and will deliver a higher and more accurate spark at RPM. It does get hotter and they do recomend mounting it verticaly since it is oil filled and with better air flow for a longer life. Both coils are about the same price $30.00 bucks or so? Note they DO NOT recomend a ballast in the coil/module/pick up loop.

What exact Chrysler module are you refering to? Is it the same 4 pin HEI that is used on GM's? If not do you have a part number or a year/make for it? Thanks.

My interest in the 12-80 mod was the fact that it has a timming curve suited to carb's or so I have heard. That and I live in Sacramento and we have one of the largest selections of dismantlers in the west. So I figured that if I could find one (12-80) cheap I could at least trouble shoot it by process of elimination. I like the idea of going solid state and the GM HEI rout vs points since I want to have a good daily driver and the HEI mod is easy to find at any parts store if I get stuck. If the HEI set up works well with the vacuum advance then I will just buy a new one and keep the used one for a spare but at least I will know it works. I am in the process of rebuilding the hydraulics since they turned to mud over the years and then I will go through the dist. Anyone have a good way of removing Black Widow's, webs and egg sacks from a car they dont seem to come off with a hose : )

The standard 4-6-8 cyl. 4 pin mod. Accel part number 35361 sells for $49.99 and the new high RPM mod. part number 35367 sells for $89.99 at the local Kragens. Anyone know what 74-95 GM car/trucks had the 4 pin mod's in them? I will look at the junk yard for one to see if that is the problem but dont know what car/truck to look for. Also anyone have a lead on how to test the 4 pin mod with a Multi Meter to make sure they are good? Thanks again.

Just got done looking at the GM HEI conversion and it looks good. I noticed one person used a Accel brand one and since I have a Accel super stock coil I think I will look for one. Anyone have a part number for the GM/Accel part or just any GM HEI 4 pin mod. ? Also I read somewhere that the onlder 240z Tach's may not work with the HEI mod? Maybe that was for the ZX altenator swap I was also looking into? Bah! too much good info on here I get it all confused : ) Any links to a site/write up that has clear wiring instructions? And thanks for the info/help.

I was hoping someone might know what year/car the Dist. and Spark box came from that way I can find some test info. I think the Dist. came from a early 280z (75-78?). The spark box I have no clue on and seems everyone one else is using the E12-80 as pictured below. I will search for the GM HEI set up on this site. The Black and white wire that goes to the Tach. was conected to the coil but I will check to see if it is conected to the Tach. I noticed that the Ignition key lock and the door switch's are also in line with the Tach/Coil loop. Any chance that a bad ground with one of those may be problem? The guy I bought the car from does not speak english very well and I dont speak Asian? So all I was able to make out from him was that it only stoped when he crossed the terminals and that his brother/freind installed the Dist/Box set up? I will head to the junk yard and try to find a E12-80 box since that is the cheapest.

Hello I picked up a 9/70 Z and the previous owner said he put the battery terminals on wrong and fried something? The starter works and that fusible link is fine, I have lights gauges etc. but no spark. It has a magnetic pick up dist. with the numbers D6F4-03 7303 22100 N4301 marked on the side. It has vacuum advance and the wrong timing plate/base? The spark box is mounted on the firewall with HITACHI E12-12A marked on it. It has an 8140 Accel 12v Super stock coil. The previous owner said his brother put it on so I assume it's installed wrong or don’t work? Here are some pic's of them maybe someone can identify them and suggest the correct installation or some test procedures.

We should burn all the lawyers and polititions at the stake! I live in California and they have yet to pry my guns from my cold dead hands and they will have to do the same with my new Z.

Oh and thanks for the welcome : )

Here is the spark box.

The starter works but no spark at the plug. It has a magnetic pick up dist. with the numbers D6F4-03 7303 22100 N4301 marked on the side. It has vaccum advance and the wrong timing plate/base? The spark box is mounted on the firewall with HITACHI E12-12A marked on it. It has a 8140 Accel 12v Super stock coil. The pevious owner said his brother put it on so I assume it's installed wrong or dont work? Here are some pic's of them maybe someone can identify them and sugjest the correct instalation or some test procedure.

Hello I just purchased a 9/70 HLS30-10031 white 240z last weekend. She has a very thick stack of records from 1970-2003 with only 3 owners not including me. She has her origional white paint with no body damage other than door dings. NO RUST through spots and only minor surface rust where the paint has worn away. With only 130k with a numbers matching motor she will be a great resto/driver prodject. I had to tow her home due to the previous owner connecting a battery backwards. I get no spark but I am trying to figure out the electronic ignition and dist. set up now.
