This is due to the construction of the gauge: It is a balance between the voltage of the battery and the resistance of the temp sender. I would suspect the temp reading here. check temp sender and gauge!

I tried an electric fan also. It makes less noise as the original fan on the waterpump. But, the engine did overheat and I needed to go back to the original mechanical set-up. What also could be the case is that the temp sender in your fresh new block is not according to Avanti spec. I did put an resistor in series with the temp sender to get correct readings. You can also try to put the old sender in your new 350. So, this did not work although I put a lot of effort in it:

But, if you live in a relative cool climate, normally, even with alcohol in the fuel, you should not get boiling gas in the carburator. My Avanti did have a sporty cam and ran a bit hot. I did fit a thick gasket between intake and carburator, that solved the boiling. Also, check the timing. If off (to late if I remember well), the engine runs hotter then intended.

Well, I have aicon and this cooling kit on my '69 Avanti too.

A project indeed...

It has nothing to do with airconditioning but all with cooling of the autotrans. The hoses on my '69 Avanti II were gone too. Here's a pic, one hose is visible.

If the hoses are reversed, the power would go in the opposite way, right? Getting the hoses right is mind blowing. My system next to the car:

Good write-up, i'm considering doing the air by myself. This will help a lot!

Oh, year, right, did not find that before: https://www.parts123.com/parts123/dyndetail.pta?catalog=0001003a&uKeY=AADCL I'll give them a call as I have so called "saddle leather".

Hi Guy, You did a nice job with vinyl! Will you redo the seat too or have them done? I'm looking for one that can do my seats. But in Europe, this is impossible. So, now I'm trying to find an American that can make the covers that I can mount myself. I have the small, thin front seats like the early Avanti's have.

I think it is used to fix the padding above the side windows and the roll bar in the middle of the car. The suggestions above do not match with my findings in my '69 Avanti II

Thanks, did not have this. Now I do, who knows, might be handy in the future.

I did post the same question as you did without response. I live in europe so shipment is even more terrible. That's why I made one myself. Not many will see the difference. With a template (the old bezel) and some nice material, it's an easy job.

I've made one myself from an old aluminium suitcase:
