The user agrees to the following terms:

All information that you provide to us for your membership is correct.
You will not use your membership to spam, harrass, or exploit other members in any way.
Vulgar, Abusive, Racist and Sexist Language will not be tolerated.
Commercial-type sales postings will not be allowed.
No mass posting or flooding of the boards is allowed.

VIEWING MULTIPLE TOPICS ON SCREEN: You can choose to see more than 10 Topics at a time ... Log In and choose "Preferences" from the top bar on the Forum page. Scroll down and Change the "Default Topics Returned" parameter to 25 or 50, and save the changes. Since this setting is stored in your browser 'cookies' (if enabled), it seems to use that stored value even if you are not logged in. So, if you use a PC that you haven't logged into the forum from, the setting still seem to remain at the default.
EXTERNAL PHOTO LINKS ON FORUM: You can still use external photo links in your posts on the new forum. They follow the rules of any link in that they have to have the URL link qualified down to the full image file name (example: .jpg). The links will open in a new browser window, the same as an uploaded image attached to a post. Since an image attachment to any post does not display inline with the post, the results are the same. You can use multiple external links within a post. This link is from photos on a site from Don Clink's 'Deuce@75' albums:

Using links from photo sites such as Photobucket can help in "size" issue with uploaded attachment files. For best viewing in web browsers, photos should be around the 800x600 pixel range, and probably not more than 1024x768. Most cameras today store HUGE jpg image files, as the default settings are in the 7, 8, 10, and 12Mb image sizes. The image files that are then attached are very large, and the browser can't display the full image size without using the scroll bars. Use the re-sizing functions of your photo editing software to reduce the image to 800x600, which reduces the file sixe and the image load time in the browser. Don uses Google's free Picassa3 software, which is an excellent photo management product. All of the photo albums of the Deuce, Grand National, and Auburn that are links on the NORG site were built using Picassa's web creation functions. And it's free? (THANKS to Don Clink for the info!)

Don't forget the safety glasses. Even at 4 lbs stop leak plugs hurt when they hit your face.

"I have used a bicycle inner tube cut to size and clamped to the heater inlet and outlets. Use a hand pump to create a little pressure and check it under water. "

I like that idea!

I have used a bicycle inner tube cut to size and clamped to the heater inlet and outlets. Use a hand pump to create a little pressure and check it under water.

You should wear safety glasses when you do this. If someone has uses stop leak in the past to seal a leak, the plug will come out with more velocity than the pressure applied. I like to test them with 8-12lbs pressure, but 4 lbs is sufficient to show any leaks.

I'd like to reiterate (in part) my earlier advise... IF you go to a radiator shop, be certain they do NOT apply in excess of 4psi.

Heater cores are notorious for having leaks, even today. When antifreeze coolant is used, the smallest pinhole will leak. If you don't have a good radiator shop nearby to check it, you can hook it up to the cooling system to run it and observe for leaks. New cores for old heaters are mostly impossible to find. I'd install some Barr's Leaks, just to be sure.

Jim, your 32 is a non pressurized system, unless you added the overflow valve from Skip Haney. A radiator shop can pressure test the core for a very small fee.

Jim, hope you are kidding there. Most water systems have FAR more pressure then any radiator cap would create and would likely ruin any heater core, new or old. You need to do this in a controlled environment with a gauge and a way to regulate the pressure. (My well pump puts out 60 lbs.)

OK so since I am on a city water system where we have good water pressure I am just going to plug one end and hose clamp a water hose to the other and turn it on full Blast.

It is a stock 32 4 cylinder which does have a water pump. I don't know if that makes it a "pressurized system" or not

1932BBs advice will in fact tell you if there are leaks. And, if you are running a non pressurized system, you'll most likely be fine with that method. What it won't tell you if there are any leaks "lurking". In other words, leaks that won't show up without pressure being applied during the test.
IF you are running a pressurized system, I strongly suggest you pressurize the core to that specification.
The core must withstand the pressure you will be applying to it once installed.
Or, simply check it under water for the possible escape of trapped air, reassemble the heater, install the heater, run the vehicle, and then find the leaks that develop under pressure.

I like 1932BB's method, however, if you pressure test anything, use water to pressurize it. Never use air. This is because air will compress and if the vessel fails, it will explode possibly causing injury. Liquids, for all practical purposes, do not compress, and, if the vessel fails, there will be no explosion.
