is there a way to junk yard find a ignition system?


I have a slant six set up. would the "ecu" work for my v8?


and I have the coil of the v8 and the dizzy.


I read somewhere all the dizzy are the same.




can I use the slant six dizzy?


im going to try.

Mr.4spd

I'm doubtful about the distributor, but I believe the ecu will work. Make sure to update us after you try.

Coil with ballast resistor yes (should be electronic coil for electronic controller).

ECU yes.

Distributor yes with a six cylinder reluctor conversion (very reasonable cost).

6cyl & v8 dist are NOT interchangeable, everything else would work !!

a minor history note: in the 50s most of the Chrysler dist was duel point. with an 8 lobe dist cam. the points over lap making the dwell angle go from 27 to 42. getting more current saturation in the coil. many people had trouble setting them right. i found a trick to set them with OUT a machine right on 42 degrees.

Mr.4spd

I've gone electronic, but I'm very curious what you came up with Moe.

Coronet 500

Geez, sorry about the distributor. I was thinking of the electronic conversion kit only.

well what i can up with is centered around perfect alinement of the flats on the points. if they dont set PERFICTLY flat or this will not work. now the books say to NOT bend the movable arm. i found if you dont bend the rubbing block but only bend from the rubbing block out you will be ok. and you hold the dist by the shaft tang in a vice. block open one pair of points with card board. take a feeler gauge and cut it to be a little wider than the point flat and 3/8 to 1/2 long. use a .015" feeler. clamp the feeler in the point to be adjusted. so it is high enough to fall straight down. here is the trick. the lobe has 1-2 spots that are the highest. slowly rotate the body, with no side force, when the 2 highest spots are the only spots the feeler falls that one is set,. on all / most of the duel chrysler if you dont get 42 degrees dead on you did something wrong. then go to the other point. and to fine tune it play around with how fast you rotate the housing. and SMALL amounts of side force. i know thats long. but i could do it from dist in block to dist back in block in 15 min. NO dist machine needed. course i dont have time to go int a Carter AFB.

Also mid / late 70's they had the lean burn system. That you do not want !

I have no Idea what this is...

so my current air fuel set up is edelbrock 1407 + edelbrock 2176 bought from craigslist for awesome price. anyway what kind of dizzy can I get? I don't have much money left after I bought these guys. i cant afford a whole electronic set up. so im just trying to get it running. im not sure what kind of dizzy I have its just the stock van dizzy doesn't have any vacuum just wires sticking out.. Im setting up a engine teardown clean room tonight. if I get to the dizzy ill post something tomorrow.


the motor is from a 89 dodge b-250 van.








thank you for everyones reply.

Ok, I think I've got it now. You have a 1989 V8 you would like to use parts from a 6cyl electronic ignition.

What you should have is a 5.2L V8 that may have a roller cam and should have closed chamber swirl port #302 casting heads.

It sounds like it has the new for '88 Throttle Body Fuel Injection operated by the Single Module Engine Controller, SMEC.

The distributor will have no mechanical advance inside as the timing was controlled by the SMEC. You will need this with the carb set up you are going with.

You will need to find another carb engine distributor with mechanical advance.

The engine you have is one of the more desirable ones as it may have spider bosses for roller cam and drilled oil passages for LA heads. The #302 heads are a good head.

Have a look at the block casting behind the starter and it should tell what size it is for sure.

OK i guess tiger has NEVER seen / heard of ignition points. i feel sorry for young guys.

RacerHog

Moe... He said 1989.
Not 1939....

moe7404

I did say "a minor history note:" i guess these young guys dont care about history. i feel sorry for them. if you dont know where you came from how do you know where you are going? do you even know who Kettering is?

tigerspittingfire

yes... im young compared to the cars. im 27 haha green horn I know I know.
Ive been messing with coil over plugs with stand alone computers.


a lot of money.


I did it all with computers. im sure I can learn to do it manually haha if I learn correctly

moe7404

"coil over plugs" 20 years ago i predicted we would be using them. if in next 5 years we see them on Top Fuel cars i will NOT be surprised. when i was learning cars a 4 bbl carb was high tech. but even learning computers you are still doing what i did. you are experiment to see what works and what doesnt. and learning is what its all about my grandfather had 6 diff patents. and when my mom says i am just like grandpa smith i take it as a complement. KEEP EXPERIMENTING!!!!!

Mr.4spd

Jeez, Moe, how'd you come up with this? Pretty ingenious. I'm guessing you were a young man with little coin and in need of a distributor job? You started messing with it and beat the system? I love stuff like this.

moe7404

if necessity is the mother of invention surely laziness is the father.

Frank Zappa was a great man Moe......
