Mopar 413/426 Max Wedge block casting number confusion

wawarnick said

According to 440 Source, casting 2205697 is a max wedge block. 2658836 is the casting number for the later truck/industrial block. Are you sure the block was original to the motorhome? Looks like you have a max wedge block.

Not absolutely certain, will look at it and post pics later today. It has valve covers on it with looms for the plug wires on the top of the covers, similar to 273 commando, but in inch or more higher off the covers. If I have time I'll pull a head off
