Re: Deluxe heater

I'd think that someone may have changed that core to an aftermarket one that was actually but possibly unintentionally made to handle the higher pressure. Or it had been re-cored at a radiator shop at one time.

The cost for one that will handle the pressure is the same as the cost for one that handles a 4 lb cap now.

I've got a few of those heaters around but don't know if any of them can be made show worthy presentable.

77 C 30 dualie, 454, 4 speed with a 10 foot flatbed and hoist. It does the heavy work and hauls the projects around.
