Only after sitting a while. It clearly is fluid and air gurgling.

And is that something to worry about? Air in the heater core. How would I remedy that? It’s a new sound...

292, 4speed, completely stock. It last for a quick second right after the engine starts. You can hear it loudly rushing forward.

After siting for a while I hear a rush of fluid (gas I am assuming) from behind me moving forward towards motor. Is this normal? It sounds to be on the pasanger side....
Thanks ahead of time guys!

This is the day I picked it up off the farm. It cleaned up well. Little bit of rust on the roof . All around good truck. It cleaned up well. It has the "wrong bed" option on it. It's growing on me

Hi guys!
Just bought me a 1963 F100 292y-block.
Trucks in great shape and is running every day.
This looked like a good resource.
Glad to be part of the conversation.
