Anyone hear of a new Dart SBF Block comming out?

i think you are thinking of the blocks where all the mains have 4 bolt caps.
I thought i saw a "sportsman series block" (like the R302) advertised with 4 bolt center caps only.
Thanks for the replies,
I'll check MFF Mag.
 
1/2" head-bolt bosses are reinforced and blind-tappered.
Uses either stock type oiling system or priority-main set-up.
Four-bolt steel main caps with splayed bolts on center 3 caps.
All factory parts bolt right on.

It's called a Dart Iron Eagle block.
