Fuel leak???

[Cudajason]

I don't know what else this would be.

It seems to be coming from the base plate on my carb, maybe the throttle shaft??

I am thinking new throttle shaft seals or maybe a new baseplate (but that seems extreme, unless there are other benefits).

Thoughts?

Common , there is an air gap between the shafts & throttle plate , if fuel is perculating from heat it will sit on the closed plates & trickle out the side .

There're no seals in the throttle shafts Jason, just the fit between the shaft and the carb body. There are kits to bore the body and install brass bushings. If you grab the throttle arm and can discern any real movement when you pull up and down, you may be a candidate. You may also want to consider installing one of the aluminum plates that install under the carb and by virtue of it's extending out from the carb/intake junction, disburse some of that heat.

Could it be a little oil wicking up from the manifold bolts? 
Solved with a touch of sealer on each bolt's threads.
It's happened on my 440, not sure if it's possible with a small block.

That makes sense, seems to only happen after a drive.  I was running about 200 all day today.

Hmm interesting, I could have sworn in my last rebuild kit they have throttle shaft seals.  Maybe I am miss remembering that.

I think that is my plan for now, a 4 hole spacer. and see what happens.

that is possible, although I did seal the intake bolts.  The bottom of the carb is wet to the touch, so pretty sure its fuel.

looks like i have about 1 1/4 inch of clearance to the hood. I will pick up a 1/2 inch spacer this weekend and see if that helps.
