electronic ignition or point. I have something perfect for that a mech prestoligt with a petronix in it. Think it is from a 273 but has one heck of a curve in it. Did a bit of majic to it since it was no longer stock.
Some people think that dogs can't think and reason, she was one that definitely could...
Electronic...
I am sure I have some 340 ones on the shelf need to know point or elect upgraded
Send him this this is what is done all to stock specs except the petronix one.

We put the MP electronic ignition in it with one of the trailbeast distributors with the curve limiting plate...
But if you have something that will work, I trust your expertise and will let him know... Hopefully he hasn't ordered another one yet and he can get one from you...
What was the curve limited to mech do you remember the number on the slot?
What would you recommend for his combo???
69 340 (not sure of the compression, but I think around 9), with LD340, Holley list 80457 600 vacuum secondary with lighter spring in the secondaries, Doug's headers, 727 trans, and 3.55 sure grip 8 3/4 axle... Here are the actual cam specs from when we degreed it:
Lift @ valve: .391"/.386"
Dur @ .050: 213.5/211
Lobe Centerline: 112/108
Lobe Separation: 110°
Prob that 72 340 would be a good canidate or that 360 with the curve in it can look at the specs again. Running a mild cam?

Oh I believe they can for sure. They can also tell time! Especially when it is time to eat lol.
We didn't look at what slot was installed when we took it apart....
We put it back together with 14° slot, and the light spring and I installed one of the MP light springs on the other side.... But then it didn't have any curve on the car when idling at 1000 - i'm not sure if we were idling high enough to use the curve by 1000... That's why I was thinking we needed a distributor machine to see where it was at....

I just found his actual compression is 8.11 from one of my notes from the build...
Just saw the specs let me look at that 360 one in the shop in a bit can let that go cheap did it for a guy and no pay, if not the 72 340 will work great.
Two light springs whacks the advance all the way in right away. around 1500 rpm or so depending on the spring tension. Great for a drag car not a cruiser.We didn't look at what slot was installed when we took it apart....

D_mn Karl.Had a hell of a day yesterday...
Eddie came over with the Dart and we had to redo a few things that the trans guy had done.... This trans guy (John Cope) is supposed to be good, but we found some issues with his work... The intake that he took off when he changed the lifters was not torqued to spec, the throttle cable bracket was bent waaay out of square, the stud on the carb for the accelerator cable was LOOSE, kick down was not adjusted, the header collectors leaked and we had to put new gaskets on them...
Needless to say, we will not be using him any more.....
There's supposed to be a different guy who is said to be a 727 trans specialist in northwest IN that we are going to try for our next trans jobs to see how he does....
Then when we looked at the distributor, one of the wires was only hanging on by a few strands, so we tried to take one from another distributor that I had.... That turned into a fiasco....
After changing the reluctor plate with one from my new distributor, we also changed one of the springs to a lighter one for a better curve, then we installed it and went to tune it, and there was no curve.... Just a straight timing from 1000 to 2500 RPM.... So we took it apart again to fix that, and when we were putting it back together it would spin free by hand, then get a hang up when we were trying to put the reluctor back on.... It started getting dark, so we abandoned that and installed another distributor that I had an Accel....
When we installed the Accel straight out of the box, we could not get it timed right... When we had it at 20° initial and 36 total, it would back fire... We backed it off to 15° initial and it still backfired.... I ran a sweep to get it to max vacuum at idle and it was at 34° initial.... We set it back to 20° initial and hooked up the vacuum advance, and it was way over 45° total advance and back fired even worse....
So we set it back to 17° initial with no vacuum advance with 34° initial and took it for a test drive and it was terrible... Very sluggish and the exhaust is now very loud - we think we blew out one of the mufflers with all the back firing while trying to tune it....
We didn't feel comfortable with how it ran, and it was dark then, so Eddie got a ride home and left the Dart here......
All this headache over an almost broken wire...
Cope - I know his rep for parts and rebuilding transmissions has been good. Didn't know his place did installs. Obviously I'd not use him for that again. Hey my friend handed back my wagon with stuff like that. Bracket on the kickdown missing - hung up the shifts first drive out, later found manifold and engine mount bolts 2-3 threads out, broke the charcoal canister's fuel tank vent connection - didn't tell me - 'fixed' it with brake line. Truth is my friend had little to do with it - his guy did the work, but that doesn't change anything. Still friendly but...they'll never work on any of my stuff again.
All my Barracuda's 727 rebuilding stuff came from A&A. Cope has a few things Rick doesn't, but I was working with Rick so that's the way I went. Don't know if they work on vehicles.
Backfire in the exhaust ought to be late timing and excess or unburned fuel.
but with 15 -20 * BTDC ???? That aint right. Spark wires crossed? - you know that bit me a couple weeks ago...
Try 10* - 20* initial with ported vac. depending on cam.
34* at idle is way too much. With an automatic, the max vac method is OK, but with the trans in Drive. With a manual, got to just go with the recommendation and play with it so works nice.
So around 28 mech and say 18 or so vac that is adjustable. Let me go look.
That's what worked well with my 68 Barracuda... the stock MP electronic light spring with one of the MP light advance springs...
But his engine may not like that as my cam was a larger.... But I thought that would be a good starting point...
Eddie suggested that we may have crossed one of the wires, but it didn't miss at idle, so I didn't think that we did... However it is possible, because he has some looms to organize them and it was difficult to trace some of them... It may be worth tracing them more carefully for sure...
Thanks for the advice, we need all the suggestions that we can get right now....
What's his car got for ECU? Is it hooked up to a Chrsyler box or a HEI - that's one of the things TB does or offers with.
make sure none of the wires are parallel for any distance.
Matt what are you thinking for mech/vac? Before I go look at the sheets on them. Hopefully I will get office installed at Mitch's this week by his renter.
We had a dog run,280 foot cable with a pulley and a 20 foot leash.
Doghouse was about in the middle. One day i look out and she is standing on her doghouse, on her hind legs trying to disconnect leash from the pulley.
I was suprised she could figure that out.
