hood tach placement?

hood tach placement? - 08/08/10 02:02 AM

Just picked up a 67 hood tach. It has the template for cutting and drilling but no real placemant for on the hood. Anyone know the exact location for the tach or is it just whatever looks good?

Whatever looks good sounds interesting... maybe right in the middle of the hood, that way the passenger can see it also grin

I think Vikki has a template on her site showing dimensions off the corner of the hood. I used one but I think it was for a 68 and realized before I started cutting too much. Used a hole saw to get the hump that sticks down centered in the traingual spot under the hood. Then needed to square out one end of the hole with a tin snips. Make sure to use a sharp new hole saw.

I was thinking of mounting it on the passenger side so the passenger knows when to close there eyes and start praying.....

Oh got to see some badazz pontiacs tear up the track today in norwalk. Not very many first gen. firebirds there. But amazingly there was 2 trans am coupes and 1 vert. 2 of them were for sale

This is where my 67 was put on my 400 hood.

There IS a good template that has been shown on many threads of this nature...just do a search!

The tach you purchased should have come with a template, as they all do as far as I know...

Re: hood tach placement? - 08/08/10 11:36 PM

I think Joe he said he got a template for the drilling layout but not the placement of the template on the hood....strange...

Re: hood tach placement? - 08/08/10 11:37 PM

It does have the template but as to the exact location on the hood, the instruction are vague. I want it just right. I can get it relatively close to where it should be but would like it exact.

Hey Gus, is your hood factory with the tach? Got all your measurements. Tried to go to vicki's website waited about 10 minutes for it to download template. My dial-up sucks long story. I finally gave up due to Aadd syndrome.

Thx david, now the fun part.... CUTTING. I'm thinking of using my concrete saw? You know keep the holes from getting all burred up. Was going to us the hedge trimmers but don't think they are sharp enough... crazy

Re: hood tach placement? - 08/09/10 02:43 PM

I used a 3" metal hole saw. 3" was more than enough even though the pattern shows 3.75".

Re: hood tach placement? - 08/11/10 12:28 AM

I used a 4" metal hole saw for mine (after-market tach on a '69). Worked just fine. Just make sure it is sharp, a dull one will heat up the hood without cutting into it. This can cause the paint to blister. Good luck!

Re: hood tach placement? - 08/11/10 11:41 PM

Well it's on the car... Man is the 67 tach a tall tach!!! Not sure about it. Figured for the purists I'd gotten harassed about the wrong tach if I went with the 68 tach. I think it will grow on me. My mother loves it per her words "paint it red with black vinyl top I'll be happy". She had a 68 bird with hood tach.

I have the 67 Tach on my 68. I like it better than the 68. I'm keeping it unless the car wakes up one day numbers matching!

Re: hood tach placement? - 08/12/10 02:53 AM

I like my '67 tach better than the '68 style too.

Re: hood tach placement? - 08/12/10 06:32 AM

Funny this would be mentioned about the 67-68 tachs. My 68 Bird had an original 68 short style tach. Then when I bought the one to put on the LeMans, I ordered the correct 67 tall style. At first, I could NOT get used to it at all. I almost ordered a 68 style. However, after a few months have past, I have completely reversed myself and now I like the 67 taller tach much better!

There you go bringing your personal problems into the conversation. Now stop doing that!!

Re: hood tach placement? - 08/13/10 09:23 PM

Well here it is... I measured 2-3 times and debated on putting it on. Hard to go chopping into a nice hood.

Re: hood tach placement? - 08/13/10 10:45 PM

A true Pontiac signature. I can't imagine owning a Pontiac without the infamous hood tach. That's why I just had to put one of the 67 LeMans, I clarified that it was an available option before cutting into a flawless hood!

Re: hood tach placement? - 08/14/10 01:01 AM

Drove the car today since putting the tach out there and have to say it looks mean out there. It seems to be fairly accurate too. Can't wait to see it glowing at night cruising the cool autumn air. Now I need to find me a ram air pan and open those scoops up.. No lowe's or homedepot air duct system... But true ram air power!!!

Re: hood tach placement? - 08/14/10 05:53 AM

RamAir pans from Warpath are all you need!

Re: hood tach placement? - 08/18/10 10:21 PM

What is the going price for a complete ramair pan? Couldn't find it on the warpath website.

Re: hood tach placement? - 08/18/10 11:06 PM

I know one thing, they are much cheaper now that when I bought mine. I was among the early buyers who helped pay for tooling. LOL Now you guys reap the benefits of waiting...

Before I start cutting, is this correct? I'm getting ready to cut into a really nice original 400 hood.

Thanks!

Re: hood tach placement? - 12/02/18 06:43 PM

That is for a 67/68 Tall type tach. Which tach do you have?
Posted By: Bob S.

Re: hood tach placement? - 12/02/18 07:32 PM

I assume it's the tall tack. My bird is a 67 and has the original tack on the original 326 hood.

Re: hood tach placement? - 12/02/18 07:37 PM

Here it is. I assume it's original but you never know. (Sorry for the upside down pic).

Re: hood tach placement? - 12/03/18 11:43 PM

It went amazingly well. Bought a fresh 3 5/8" hole saw from Lowes and cleanly went through the hood and understructure.

Nice job, do you want to sell your hole saw? Can you take a pic of the other side?
Posted By: Bob S.

Re: hood tach placement? - 12/07/18 02:37 AM

Not sure I could sell you the hole saw and ship it to the great white north for less than what you could buy one there. If you lived near by you could borrow it. It was $20 and I already had an arbor.

Re: hood tach placement? - 12/07/18 03:11 AM

Are you sure you used a 3 5/8" hole saw? Does the tach fit? The diagram shows a 3.75" hole.
Posted By: 68tpls400

Re: hood tach placement? - 12/07/18 01:24 PM

I belive even a 3" hole works. The stock opening is way bigger than needed. I used a 3" saw that I already had.
Posted By: Bob S.

Re: hood tach placement? - 12/07/18 02:23 PM

I saw you posted above that a 3” saw would work so I figured 3 5/8 would be fine. They didn’t have 3 3/4. Didn’t try to install the tach yet. Need to take it off my other hood.

Re: hood tach placement? - 12/07/18 10:02 PM

I am going to dig out my old gasket to see how big the hole is. Can you get a gasket for the hood tachs still?

Some outfits repop them, but they are nowhere near original. I put a light bead of clear silicone around the bottom of my tachs, then let it dry. Then later, set it on the hood and tighten it down. That is a better seal than the hokey repops.

Here is a 67 gasket from AMES

"Part#
FD355
Description 67 HOOD TACH GASKET (RE)
Net Comments THIS GASKET WILL NOT FIT THE REPRODUCTION TACH WITHOUT ELONGATING THE STUD HOLES. THIS GASKET IS USED BETWEEN THE HOOD TACH AND HOOD. THESE WERE ORIGINALLY USED BY GM IN 1967, BUT OFTEN LOST BY RESTORERS AND BODY SHOPS WHEN RE-PAINTING THE HOOD. QUALITY IS EXCELLENT."

Hi All!
Getting ready to cut a hole myself... '68, with 68 short tach. Saw youtube (Scared Shiftless) install, but they went through at a point on the hood that centered within the hood's triangular under framing. That puts the hole in a little bit diff place than the template Bob has I think... any thoughts or comments ? I, as we all, have only one shot at this....yikes!
I'm going to take Bob's template and test the spot to see how diff.... will let you know~
Posted By: 68tpls400

Re: hood tach placement? - 01/11/19 03:58 PM

The hole goes through part of the underside framing. So if you say where it missed the framing, it would be in the wrong place.
The template on fgf is within an 1/8" of original.

Get Type ll - short type template

Don't use YouTube SS location.

Re: hood tach placement? - 01/26/19 04:40 PM

I finally moved my tack to the 400 hood. I had to enlarge the mount holes a little. 3/16 holes have no margin for error whatsoever. Apparently I didn't locate the holes perfectly. Also, with the 3 5/8 hole, it might be tricky to replace the light bulb. So a 3 3/4 hole might be optimal or add a little extra to clear the socket.

Does the new tach fog up?
