I have a 306(302 .30 over) roller block for sale. Its cut for a D.S.S. bottom end girdle already, and pretty fresh on all of its machine work. The only thing needed before installing would be a cylinder honing (like 20 bucks for the part from Sears, plug it on a drill and hone away, really easy). No idea how many miles on it or anything of that nature (I can get casting numbers and stuff for year if needed, but roller blocks were all decently new), but the block looks to be in VERY good shape.

I bought it from NA306Stang for $150. I'm selling it for $150. Plain and simple. Selling because I'm either selling my entire car and setup if I can't manage to insure it somehow, or going with a 351w base for more power.

 

Bump for a killer block the 30 over bore has like 1500 miles on it if i can remember right!!!
