I have a 413 shortblock with a casting # of 2658836, 4.180" bore, it is turquoise color, has the unique ribs on the side of the block, steel crank with 8 bolt flange, holes ARE tapped on the flange, no centering ring on the flange, all my research says the 8 bolt flanges have un-tapped holes? But what puzzles me the most is there is no casting date on the block, only the casting number mentioned above, number 6 cast into the block in a few places, but no D/N shift indicator and no date, id pad is blank as well, just trying to figure out what year this is, also has 1851535 std RB rods, dished pistons and a gear drive gear on the crank, cam gear is missing. Anybody an expert on 413 industrial/HD truck engines?

Anybody an expert on 413 industrial/HD truck engines? I'm no expert on those motors but my volume #1 casting book shows that casting number as a 426 industrial block with no casting date codes The tapped crankshaft tells me it is a later, after 1962 RB industrial crankshaft, maybe a marine motor to start with IHTHs

"I'm no expert on those motors", me neither. Possibly a non automotive purpose. Electric generator or an Agriculture (water pump) motor?
I have mechanical Aptitude. I can screw up anything.

I've used three of the industrial 413 H.D truck blocks to build 426 motors as well as afourth one for my 1963 Plymouth Fury with a 4.150 Mopar stroker crank in it, none of them had real thick cylinder walls after sonic testing them The first one had a external freeze crack that the machine shop didn't find when they magnafux it, it had a crack cylinder inside also I ended up junking that block On your deal I would have the crankshaft offset ground to BB Chevy 2.200 rod size and increase the stroke to 3.910 and run a set of 7.100 long BB Chevy type H beam rods with a set of custom pistons Make sure and have the block sonic tested and magnaflux before starting so you can decide before starting what bore size, stroke, compression ratio and so on that you end up with

I’m a big fan of these engines .... but I’ve never seen one with the crank flange extended. You must have one that was truly an industrial one - like off a oil or water pump OR something out of a large truck. I have about 10 of these and they all came out of a motor home chassis
