This is just something I can't fix with the car up 18" on jackstands.
Today, I worked out my choke problem (or I think anyway), trans problem (thanks Steve O.!), and generally had a good day with the car. Drove up & down the street, gave it a little gas, no obvious problems yet.
I went inside to eat, my aunt & uncle came for dinner. I go back outside to 'test' my choke adjustment, car was back down to 110 deg. Came right to life, I am hoping that was done right.
However.. Right where the back of the block was, there were two circular spots of coolant. I grabbed a clean paper towel and blotted some up, and it surely is coolant.
Its not burning coolant, I am almost 100% sure. No indication of white smoke, just a little raw fuel at idle. No burning coolant smell.
Now, as far as I can tell... the only thing back there are freeze plugs.
I just had the engine rebuilt, new cam and higher CR.
Tomorrow I am going to call the guy in town who does the oil on my late model pickup truck. Its a little shop with a lift, and I am going to ask him to throw it up on there.
Question: I was under the assumption that freeze plugs on Mark IV BBCs are pressed in on a machine. (If it is the freezeplugs). Can these be tapped in with a hammer?
And second, if its not the freeze plugs.. what could it be? Third-- if it is the freeze plugs, and they are almost impossible to get at without removing the trans bolts and motor mounts, and tilting the engine up.. what is the chance they would blow off the block while driving? Would it be safe to just use some sort of high temp gasket stuff if they are hard to get at?
I basically need to get this fixed.. can't go to the track with leaky freeze plugs..

Thanks..

check out the intake manifold gaskets at the back of the block where it mates to the heads, could be leaking at the water ports on the corner of the heads.

If your friend has a shop, he probably has a pressure tester for the cooling system. Looks like a small bicycle pump with gauge. Pump it up to about 16 lbs and look for leaks.
