Very cooool !! old skool race stuff great collection for a vintage cackle race car back in the early days before KB started making his own aluminum blocks he did a lot of tooling and mods on the over the counter service replacement steel unstamped blocks for the fuel race cars adding billet main caps and clearance for the early stroker cranks range from 4" to 4.150" and common 7.100 connecting rods usually aluminum with custom Westcott forged pistons or Areis it would make good sense to take advantage of that on a rebuild for a 472 0r 484 cubic inch build they were awesome then and still today.
