speedometer question

[tekslk]

When changing speedo from a 120 to 150 mph does anything other than the head need changed? This is on a 67 barracuda.

If the speedometer cable attaches the same way it will work as far as I recall.

I ordered a new 68 speedo cable push on type because my 67 had the screw on type.

From what I have read but have not personally done, you can swap that part between the two speedometer so that way you can use your original cable.

You may end up having to change the gear for the speedo in the tranny, but if it physically hooks up it should work right.
Who knows if the drive ratio is the same as our cars use (Thats why I mentioned the gear)

 

[tekslk]

What gear in tranny? The one that calibrates your mph?

I have never changed the speedo tranny gear and I don't recall the speedo being off after a swap.

Thats what I want to here, I may try the swap on the ends, I never thought of that.

That's the one.

That would be nice, and it was the only thing that I thought might be a detail to have to mess with after the swap.

Screw it.
You don't need a speedometer that bad.

My brother told me the other day that he's not going outside any more unless the degrees of temperature is at least the same number he is old.

He's 54 so he's going to spend a lot of time inside this winter. :-D

Global warming scientists are stuck in pack ice that wasnt supposed to be there! Complete BS....It was 78 here today...;-)

If the speedo was good with the 120, I think your good with the 150. All the heads should be calibrated the same. The trans/speedo gear should only be effected by a change in rear gear or tire size. At least that's my dealings with GM stuff.

Oh yea, it's in the upper twenties here in the "low country" Sc. Early next week looks to get down to the upper teen's a few days. Where's my global warming when I need it...:banghead:

Drive your car in that they run like hell in the cold weather. I had mine out christmas day at 22 and after 10 miles on a warmed up motor it felt like a 50 hp gain.
