Canted 393, I just done my heater core about a month ago and I truly think it's easiest to do it with the dash pad and the entire lower dash out of the car. Mine is a non A/C car and it's not too bad with everything out of the way. I have no clue if it's worse on an A/C car.

Be very careful with the clips on the heater box. Don't pry them off. They snap off a certain way. Go watch Don Rush's video on it. He shows a ton of great tips.

Thanks for the input, I have watched it and that's why I decided to make it a winter project along with the motor and trans rebuild.

Those 2 hoses I thought disappeared behind that little box actually go into the box...
Is that your little box? Did you remove it?

You might try just trimming some off of the end of the vac hose ~ past the leaky section, and reconnecting it.

I simply disconnected and plugged off all the vacuum hoses for now. Still working on getting it to run better. It was running decent before I put on the new brake booster and master cylinder but now it's running rough as can be today. So I've plugged off every vacuum line but the brake booster and I'll work on timing and tuning the carb today and then back track into hooking the vacuum back up to the other stuff one at a time.
