Don,
My high school local Pro Stock hero Sonny Bryant built this crank.
Stainless,
I think you know us too well.
Yes, we'll see you on the salt...
Sparky,
Yes this engine has oil passages down each side of the block. You might also notice that the cam tunnel is totally blocked off from the lower crankcase.
The 1st photo has yellow arrows pointing to the passages at the front of the block. The 2nd shows how they are laid out in the crankcase before the crank and squirters are in place.
