72 LT1 engine vacuum lines
Does someone have a picture of the engine without the air filter on for the 72 LT1's. I have been looking everywhere for a pic on the web and mostly all have the air filters on or the engine has been modified. I am looking for the routing and placements of the vacuum lines for the carb, intake,smog etc not wiper or lights. All the books I have including the AIM and GM books don't show it complete. Hopefully someone has a LT and took a pic of their engine without the chrome covering everything.

Dr Rebuild has best products and good engine hose diagrams for your LT-1 but, sometimes you get major attitude when you ordering parts from them (although I can see why the bad attitiude when he took the time/$$$ to make quality stuff and most people can't tell the difference between his stuff and the other junk being marketed.) Here is a link to their catalog: http://www.docrebuild.com/dr-r-web/SPARK2.pdf

M. F. Dobbins. Pricey, but worth the cost. Lots of underhood photos of original cars, including the LT-1s. Photos are black and white, but will probably help with what you're after.

Thanks Mike, I am going to search down the book you mentioned. I talked to Dr. Rebuild and they have all you need for the headlights and wiper door but no one seems to have the engine vacuum itself. Everything is on my car except the TCS. So now I have to figure out where everything went with the vacuum set up. I am still trying to figure out the black wire coming off the trans TCS switch to where it goes. I have the boot and about 2 feet of black wire coming off it but can't see anywhere in any books of where it connects into.
