Less than a month and I scored again.

I don't know but ol triple R was saying it means something.

I like 318willrun's idea of what it means because a good slant is always your buddy when you need it to be reliable.

BH castings are supposed to be somewhat thicker and stronger. I don't know anything about "BF" castings. Not that it matters. A free slant six is good no matter what. Nice score.
