Re: wierd cooling system problem noise ?
That engine is a 1965 model 327 (or 283?), using a bypass? Old style heads? Hello?

Re: wierd cooling system problem noise ?
That factory bypass was used on mostly medium duty trucks back in the day but some light duty trucks came with them also.

Re: wierd cooling system problem noise ?
Good info. That's something I never realized, so it's not new for small blocks. Interesting.
I looked at 5 different 60's small block cast steel intakes on eBay they all have the bypass nipple attached. I never noticed that before.

Re: wierd cooling system problem noise ?
The factory small block thermostat bypass you posted a pic of, actually uses a piece that installs under the thermostat housing which the bypass hoses attaches to, What you were seeing on those 5 cast iron intakes is likely the heater hose nipple.

Re: wierd cooling system problem noise ?
I am losing my MIND trying to read and learn all of this. So far Google has me deep down a rabbit hole haha. So, I think I can run a regular reverse flow long pump (Like from a TPI 3rd Gen camaro) and just run a nipple in the top of the water pump to the 3/8 NPT water bypass in the front of the Edelbrock Vortec intake that I have?
