[TransAm 474]

I filled my 461 with filler from Pontiacdude way back when I built it, I filled it to the bottom of the center freeze plugs. To be honest, it runs way cooler than the previous non-filled 455 did that was in it, but the 461 is a complete different combination than the 455 was, and I built the 461 with alot tighter quench, so that may have also contributed to the difference as well.
