Here are dimensions that I measured from one of Ed's
old cores.
Overall
dimensions- 13.5” x 9” x 3-5/8”
Core dimensions-
10.5” x 9” x 3-5/8”
Volume
of water it will hold- 39 oz.
As you can see, the core is 3
inches narrower than the outside dimension, so if you were quoting outside
dimensions, your core would likely end up being about 437.
I don't know if the 5/8" inlet/outlet tubes
would be too restrictive to flow compared to a radiator that would be made with
1" NPT inlet/outlets?
5/8" ID (if that's what you meant) might work, but it will
be on the small side. For reference, some folks are using AN-12 hose I
believe, and that would measure pretty close to 5/8" ID. Believe it or
not, measuring the actual ID of an AN-12 hose was on my list of things to do
today. I have measurements for most other
sizes.
