Track Pic Of Blown Plug- Rather Unique
This is a picture taken by track photographer at HRP last Sunday night when I blew the rear freeze plug. It was sent to me by the Rumble Bee owner I was racing at the time it blew. Look very close under the truck. You can see the freeze plug just off the ground and water spewing out. Would have been a beautiful picture except for that.

I finally gave in and loaded Smarty SW 4, TST 3/0, EZ 2 and ran 13.0s @ 103, but I needed to get home and gave up for the night.

Well I have seen a few posts of the same freeze plug coming out. Most were with performance mods. I assume the higher fueling rpms created enough pressure from the water pump to blow it out.

yeh the combination of the headgasket leaking slightly from increased cylinder pressures combined with the speed of the water pump cirulating water pressurizes the system enough till "POP".

Fuels hard and shifts in the 3300+ range to 3rd and OD I think, still trying to watch about 3 guages, tach, speedo, TST Remote, hold the TC lockup button down, keep it straight and answer the cell phone at the same time .
I keep saying well this run I am just going to take it easy and watch this gauge and nothing else. Then I get to the lights and the street racer in me takes over and I am not thinking about anything but best R/T and beat whatever is next to me to the lights.

That makes sense... how much cylinder pressure do you reckon is getting through the HG into the water jacket?

I think some of it may be that plug being so close to the back of #6 cylinder and the block expands a little due to the heat from that cylinder. In addition, the lip on the plug is very narrown not a lot of surface to grip. Thank goodness fro JB weld.
