68 GT500 engine bay questions
« on: October 26, 2018, 08:03:48 PM »
Hey Gents!

I've finally received my engine back from being rebuilt... 14 months later. I'm sure I'll have a lot of questions moving forward, but for now just a couple...

Was there a carb spacer used?

Anyone have more information on the vacuum fitting on the front of the intake by where the coil rests? Pictures?

Same for the tree that goes in the thermohousing?

Is the pulley on the AC compressor black or silver like the case?

Thanks!

Milo

You will benefit from the info you find on http://www.thecoralsnake.com/  website  . Yes on a thin bakelite spacer on the GT500.The vacuum valve/switch on thermostat housing is a three nipple C8AE marked unit. Most Typical the pulley is zinc silver to match the donut shaped electro magnet and not painted like the compressor . Picture is of D0AE marked valve just what I had handy .Looks the same except different engineering number.

You both are absolutely right - Pete's website has been a godsend. Without it I'd have had dozens more questions. But, as a newbie (and zero disrespect - - as someone who has built a few websites in my day and knows the time and effort that goes into building content for every page) there are some areas that aren't covered. Maybe it's because some things are more obvious to a seasoned restorer. I'm happy to speak further on the UI or content gaps, if asked of course, but barring that I'll stand behind pure gratitude for his time, effort, and expertise. So, thank you Pete.

Chris and Bob - thank you, as well.

Chris, I do have a question sorta in the form of a statement - in the picture you posted of the vac tree, I noticed that the hose from WP to block is painted blue, along with the straps. I have to assume that its correct, though have never noticed it before...?

That is where something that looks totally wrong is actually correct. I try to make things look a little better than back in the day where it looks like the painters air hose burst and sprayed all the wrong engine compartment pieces. Everyone builds there ride to suit there needs but for me if purchasing a car I don't like to pay an up charge for ORIGINAL SLOPPINESS. :-\

Yes that short hose and clamps would have been very difficult to install after the water pump was installed to the motor and like small blocks was part of the engine assembly then it was painted as a unit

Some more pictures and info on the PVS

Looks like someone may have broken the top nipple off and just put a screw in the hole....
When things go bad just hit the throttle, may not solve the situation but does end the suspense.

Here is one I was getting ready to plate. Plating is over kill given they are painted with the engine.

Whoever did that damage must have had something against vacuum.
