Got the tach working. I have a pertronix 3 and was worried about connecting the tach lead to the neg on the coil. I had incorrect info that the tach could be damaged by the multi spark feature.
But that is not true and in my cars case I didn’t need to add a resistor that is sometimes required for correct function of the tach.

Now I get too see how long the Pertronix functions before I get stranded like so many other have.

I installed a Pertronix 3 on my 70 El Camino. No problems for the three years before I sold the car. I had an old SW tach (1965) with sending unit that worked just fine with the P3. (Tach is going back into my 68)

Progress, hope to start assembly Monday.
Then turn car around and start on driver side.
This tread has at least gotten me off my butt.

Test fit lower control arm, took a little massaging to get back in with new bushings as expected. Had to spend the majority of the day in the yard spring cleaning, mainly those 80 trillion Sweet Gum monkey ball thingies- nastiest trees on the planet!

You'll have the satisfaction of having done it yourself...and saved a ton of money.

I took advantage of the dry weather and ran some errands in the T/A, then took the '68 down to open shop night at my son's school. I was hoping to do some more tinkering on the brakes but all the bays were full. It was fun seeing the shop kids drool over it and shout "noooo waaaay!" when my son got in to drive it home. He definitely got some cool points.

Forgot the pic...rolled over 19,000 miles in the Comp T/A while I was out today. It came to me with 16,700 in 2022 so I'm not exactly racking up the miles, but it's getting driven regularly. It apparently had a mere 500 miles put on in it in the 10 years prior to my ownership.

Since the tape player is fixed I rocked a little STP Purple while motoring around.

full tank of gas what is stopping you...lol

I could swap a HEI module faster than points on the side of the road. But, that's me. Maybe if your a points master it's the opposite.

Also, whenever anyone complains about HEI it usually seems to be Pertronix. I have a DUI and i've searched around and haven't really found many, if any, problems.

In my old speed shop install - sales days almost every pertronix failed early on.
We were the east coast jobber for speed equipment including circle track stuff.
Auto Finishers Speed and Custom.
We stopped selling them and always sold MSD, magnetic trigger.
DUI are solid as well magnetic triggers,Pertronix are hall effect.
But cross country you still can't beat points and a carb.

Just did a quick look and it seems like Pertronix sells both big and small cap distributors that can be either Hall or magnetic. Not sure why they have both. I haven't found anything on the Pertronix website yet that talks about it. On the Summit site they tell you if it's Hall vs magnetic, Pertronix doesn't even mention it is the specs on their site at all. The DUIs all seem to be magnetic. Original GM HEI were also magnetic, correct?

[KS circutguy]

yep
Also the Mallory units were always failing,
they were Hall Effect as well.

Picked up the motor for my Firebird from the machine shop. Pretty stoked about it. Lots of pieces of the puzzle are coming together on the bird.

I am going to put an exhaust system on my 81 TA today. The car is almost ready for a test cruise!

Who did you have do the machine work?

[VCho455]

Somers Automotive Machine. We've used Archie almost exclusively for over 20 years for machine work. (Did my OHC 6) We have him do the machine work and we assemble them ourselves. Once he's done with the heads we'll have the short block ready and then we'll have it dynoed at his shop.

He's a bit grumpy but the work is always on time and done right. He has a lot of regular customers who race for points so sometimes it may take a bit longer but he lets you know up front how long to expect.

Yep,I've used Archie for 30 years and turned many on to him for machine work.
