318 build up

I have a nice forged crank out of a 66 318 out of a van. So not only 273s got the forged steel crank. MT

another indicator was it used a SB 727.

Of course some 318's and 340's had forged cranks, but no need to go look'n if he has one sitting in his lap... especially one with the right pilot bearing....
