  95. jerry Says:I have a block that is marked 2468 only(there is a blank, oval shaped pad after the first four numbers), R,L, 5/27/64 with the following numbers and letters on the pad “A 426 HP 5?. The rod, piston and crank numbers all correspond to 426 hemi numbers, and it has forged crank forged rods and forged aluminum flat top pistons, but the block is a two bolt main…what the hell is this thing? Some have told me a hemi, some have said it’s a wedge, but the wedge numbers don&##8217;t work because it’s a 426 and the 426 wedge has a completely different prefix…HELP!
