Turbo 400 problems
I have a turbo 400 on a 69 396 block and I'm having some issues. When you drive it for the first 10-15 minutes everything works fine but, after it begins to not want to shift into third accept when there is no acceleration, coolent and vacuum are working properly, I don't really get why it occurs but I was wondering if I could have some input, please and thank you.

If it still has the original modulator I suggest replacing it based on years alone. And while you're at it replace the short hoses at the modulator and intake manifold using 1/4" fuel hose.

I have already replaced the line and I am getting a modulator tomorrow, it's been rebuilt 3 times and it's been 200 since the last rebuild. The modulator is only like 5 years old if that
