Slant 6 Turbo 68Dart Project

I blocked the passage by loading it up with JB. I found it by blowing on the base of the carb till I saw which hole bled to the power valve cavity. I filled it from both sides so it should be closed off pretty good.

I was thinking that the cavity was already boost referenced before since that hole led to the intake basically after the throttle plates so it should see pressure, but this will keep vacuum out of it all-together I think.

One thing I've been getting into recently is reading the vacuum/boost gauge and people have been posting lately a lot of information on what the numbers could mean. Mine reads 10 inches under idle no matter how i seem to adjust it and this seems to be synonymous to chain slop or valve timing off. I looked up a new timing set and Oreillys' has one from Cloys I believe for $25 for the two gears and chain, or a "performance" one made by CompCams for $50.

Anyone done this in the car? I'd assume just removing the radiator and fan it could be done easily enough. Maybe the radiator doesn't even need to come out, and at less than $100 I think there's no reason not to replace it even if it isn't messed up. The engine has 100,700 miles on it. I'm thinking this could be the reason I seem to be having these timing issues, and why it seems it's not making as much power as its supposed to .

Also how do i go about the removal/reinstallation process for the 3 parts? Where and what am I trying to line up because I'm assuming whatever needs to be alligned, is not if the chain is slacked a bit.
