If I remember correctly your car doesn't over heat, it reads too high. So stop fixating on that gauge!! Hotter spark is going to make it idle and run better

About time they moved that cut off date!There can't be enough vehicles of that vintage on the roads to make a difference

If it were me I would resort to ether like ZedHead. If it fires off you know you only need fuel

Looks a lot like the dark grey they used on porsche 944's

That's a decent plan but I suspect there is some significant rust at the front of the frame rails where it meets the radiator support...

Progress is good!!

I think if you can get the metal fairly clean and treat the rust, this would buy you some time until you're ready to tackle it

@LeonV that is a nice clean fuel rail setup!

I do too. Although they can be difficult to get fully plated, because the shadowed parts of the hinge won't plate. So some adjustment or barrel plating can help

That's a good looking red Z

I doubt it would build vacuum with just one 1/4" tear

None of those temps look bad

Bear in mind, the seals for the early master cylinders can be difficult to source

What is the total timing advance at 2500-3000 rpm?

Beautiful as always...
