It is my experience and understanding from others that 95% of the time nothing is required to run a stock tach dash with an HEI. I ran one in my 71 blazer with no issues and it seemed to read accurately, and many other members have stock tachs with HEI and have been running them without issue for years.

some have said the rpm's were way off and they had to install a signal filter in line with the hei lead? The thing I like to note is factory tachs were never extremely accurate in the first place and 40 years doesn't make them any more accurate I have a three speed on the floor in this truck and would like to have a general idea of rpm's other than just what I hear the engine telling me

In regards to the aftermarket tachs...I have to admit that is a mystery to me. I have tachs from three different manufacturers and they look like the same back stamping, face, printed circuit board inside the tach, and as far as I can tell they are identical. However, some vendors advertise that you CAN NOT use one of their aftermarket tachs with HEI or it voids the warranty... and a few members have had aftermarket tachs literally go up in smoke.... That being said, some manufacturers have no such disclaimer and I also know of several people running aftermarket tachs including one who has a complete reproduction gauge cluster setup and has been running it with HEI for over 5 years and 50K miles with no issues....
To further cloud the mystery some vendors sell different wiring harnesses for points or HEI....but upon inspection there are no filters or in-line fuses or anything that would change their performance...their appearance was just slightly different. SO......short story made long.....I have no clue as to why some aftermarket tachs work with HEI and some don't.

My educated guess is that there is something else going on in the electrical system of some who have issues with the aftermarket tachs (ground issue or signal issue from the HEI) OR....there are faulty tachs produced by the manufacturer (who hasn't had to return 2-3 new parts because of them being faulty right out of the box until they find one that lasts?)

The one thing I like to do is to run a separate ground from the back of the tach to a good ground either on the dash or firewall. I know the factory didn't do this....but it's not going to hurt anything and is an extra safeguard to me....just make sure to leave a lot of extra wire to make it easier when removing the cluster.

Hope that helps although there are no firm answers...

Re: Rebuild on a shoestring.....continued

Got my new floor mat in from lolife99 today. It will stay boxed up for a bit till I'm ready...then I'll roll it out in the sun before I install it in the truck...but no need to take it out now as I'm cutting out floor pans rust

Also went through more parts tonight and set aside some stainless screws for the interior, a set of misc screws and lock nuts I will need, some bulbs, defrost hoses, some spray paint I will be using, and some of the tach/vac parts.

I also polished the horn button for the steering wheel and it's shiny

Put together a bunch of parts I'll be listing on the board and some I'll list on ebay (because people seem to pay a ridiculous amount for these parts on there )

Also found a forgotten treasure I recenltly had purchased a nice black dash pad off the board so I have that to replace the mostly non-existent factory one....

Thanks

I would be in over my head but Gene of Gene's body shop is REALLY helping me out. He's going to give me a crash course in welding too which is awesome!!!

I got my cab sold so other than doors, fenders, and small parts my 72 super project is gone....which is good because I have room now in the garage...and more cash for this build

I still have a LOOOOONG way to go to be as organized as I like....I really just need space and shelving...right now too much is boxed up. It's divided by type of part...but still means I have to look through the box to find what I need and invariably it's on the bottom of the box and I make a mess out of everything trying to get to it...

Amen Brother!!!

I have this huge shop and cant find anything. I need shelving and some kind of storage where the overspray doesn't get all over everything. I Still cant believe what a mess the bodywork and paint jobs cause. I need to gut my shop and start over completely.

I know what you mean about the overspray!!! The cool thing is this time I'm working at the actual body shop...

Just got back from there tonight. Glenn (body guy) got the rocker finished (made a custom piece for the front and welded it in). I got the four cab mounts trimmed and ready for him to weld in. And we made a patch for the driver's floor pan and got that welded in. I got my first experience welding tonight......and I need A LOT of practice It wasn't too bad but I had a hard time seeing even w/ a nice auto dimming helmet...and ended up going off line a couple times and blowing through the metal around it....but in the end I got it done and other than looking like a bunch of buggers it is in....

Gene went behind me and cleaned up the welds...so it's nice and solid now...

pics to follow in a bit....

VA72C10,
When I first started welding I found the same thing with how my welds looked except I thought they looked more like Chicken Crap!!!LOL The trick is to take some metal and just practice till you get it. The problem is with 40 some odd year old metal your dealing with rust and inpurities and its way harder to weld on that. My Son Ian is a really good welder (Which Works out good for Me) and he makes welding look easy. Problem is he tends to do most of the welding so I dont practice near as much as I should. We are getting ready to weld the floor pan complete from the fire wall to the trunk on my 67 GTO Convertible and that has both of us a little nervous just from the size of the sheet metal we are welding in. Glad to hear your not having to mess up your shop with the bodywork, I forsee a two day deep cleaning for my shop in the near future before I start putting my current project together. Im really enjoying watching your build and look forward to some more pictures.

Re: Rebuild on a shoestring.....continued

I found out when I was almost done that I was holding the tip too far away...my fear was ruining his welder so I wasn't getting enough heat. Plus, I wasn't holding down the trigger long enough for fear of burning holes through the old metal. The only time I burned through was when I got off track and welded on un-sanded rusty metal. I just had an issue seeing anything when I was welding....

Re: Rebuild on a shoestring.....continued

So....I needed to make a patch panel. Gene laid it out for me and we finally found a way to use my tri-plus inner door patch....(it's the only tri-plus panel I've ever used that didn't fit--it was WAAAY off )



So...I get it cut out.


As I'm grinding my hand feels warm as the sparks hit the inside curve of the patch.....
I look down and ooops....
melted my mechanix gloves



At least I was wearing the gloves so I saved the inside of my fingers.....although I also burned my forearms....looked like tiny dots all over my arm and itched like crazy last night but feels fine today.

Re: Rebuild on a shoestring.....continued

Here you can see Glenn welding over my welds to make sure the patch is good....it'll be okay once it's ground down...

You can also see the custom patch he made from a non-tri plus rocker (the one we tried and ended up going with the partial tri-plus piece because it fit so bad...) Even on this small patch he had to pie cut it and tac, hammer and tac, hammer and tac...to get it in place. Will take the door off to weld the front edge and grind it down.


And here's the patch in...again...he had to weld over my poor welds....

Re: Rebuild on a shoestring.....continued

I'm going to wire wheel the floor plan to take off the surface rust/scale...the rest of both floor plans are really solid actually other than the same area but smaller on the driver's side. Have a couple more small patches to make to get this all sealed up. Then I'll grind down, apply seam sealer, and then paint the floor with some rust converter then undercoating. After that, the black floor mat will go down...

Re: Rebuild on a shoestring.....continued

Good to see ya givin welding a crack! One thing I learnt in trade school was when your welder is set right it should sound like tearing fabric and I always try to set the welder up on a piece of metal as thick as the job your welding. Do a few runs and fine tune it. Not trying to be a smart a$$! Just tryin to help. Keep at it mate. Practice makes perfect! Cheers

Any/all advice appreciated. Like I said...my biggest issue (besides inexperience ) was not being able to see what I was doing...couldn't see how far the tip was from the metal and even where the gap was to weld...
...before I try again I'm definitely going to practice on some clean scrap sheetmetal...to get the speed down and distance and try to adjust the welding helmet so I can see

Any advice on that? (adjusting the welding helmet) it's electronic

One thing that really helps me is a 3x magnifying lens that I put in the welding helmet. It really makes a difference in your ability to see what is going on.

Try making the helmet filter lens one shade lower so what you see is not so dark. If you go to light it will hurt your eyes so don't go way down. Just go one shade at a time lower until you can see properly.

Re: Rebuild on a shoestring.....continued

Oh yea, I also added a dark rag to the back of the helmet that covers the back of your head. It blocks out much of the light coming in from behind you or overhead so the contrast between your eyes and the welding area is higher.

It really helps in a well lighted shop or outside.

Good idea on the rag, and I will play with the settings the next time I weld. I think my main problem other than not being able to see what I'm doing as soon as I drop down the helmet is that I don't want to damage the tip of Glenn's welder so I am keeping it too far away and the gas isn't working for me at that point.

Headed over in a little bit to pick up the truck so I can have it in my garage to work on it. Will get a lot of items done before bringing it back to his shop for final welding needs and then paint!!!

Re: Rebuild on a shoestring.....continued

I have only used a cheap auto helmet once, I normally use an ol' flip down one. But as far as I remember I think no 8 shaded was for mig. I'd just start at the darkest setting and arc it on scrap metal adjusting the shade down till you can see. Hope it helps. Cheers

Re: Rebuild on a shoestring.....continued

On the welding sometimes ive found that if you have good light that is directed right at the place your welding and placed so its not faced towards the helmet it really helps you see better. Now the real advice I have for you is to find a magnifying lense and tape it to the inside of your helmet, thats how Im able to see the welding surface better. Now 20 years ago I probably wouldn't have needed the Magnifying lense.

Are you going to fix the kick Panel and the seam above where you welded in the patch panel on the floor? Ive found that the seam running across the floor is prone for rust so probably to be safe look for pin holes and weld them shut then grind that seam and put POR 15 on them to keep them from rusting in the future. These are things Ive found in my builds so Im just suggesting that they may be problem areas in the future so you might want to take care of them while you have it apart. This is a great build.
