It's NOT a Max Wedge block.
Wrong "Font" engine stampings, on the id pad.
Just a standard 413 hp engine block, nothing special about it.

41 - 413
S - 1962
That's the correct casting number though it's not unique to the MW engine and my info says the block was only notched on the exhaust side.
As for the HP stamp (low compression version), it's either got that or the HPHC (high compression version) stamp as well. With the fonts being different, looks like it could be one.
They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.

It should have the casting "AAQA" on the driver's side front. "Google" Max Wedge block pictures. It does. I have not pulled the heads yet though. Thoughts?

Yes, notches only on exhaust side of the bores.

Looks like you scored a nice set of rockers and pushrods in the deal too.
When you work on the engine check the passenger side rocker shaft - rear - in your picture it looks like the soft plug might be missing. There is a black spot that looks like the bolt hole is visible.
Should be one in each end of each shaft. Could also be that the builder hammered them in past the bolt hole too.

What diameter are the exhaust valves? What about head casting numbers? All the Chrysler 300 motors before 1962 had solid lifters and those type adjustable rocker arms. All the letter series 300 motors had them until 1964 also  I think the 1964 300 letter cars used the six bolt valve covers and the later style rocker arm pedestals cast into the heads also You may have gotten very lucky

No they did not. 1960 and 1961 standard 375 horsepower engines had stamped rocker arms and hydraulic lifters. The optional engines had solids.

I've never seen or heard of any Chrysler 300 Letter cars made before 1962 that didn't come standard with 2x4 barrels carbs and solid lifters, 375 HP or not  Mopar decided to add the non letter 300 cars in 1962 including 4 door hardtops with 383 motors

You never heard of it? OK so that makes it so? "Every human is wrong sometimes" just caught up with cab. Well look it up, ok I did that for you, read this. Or just read the factory service manual. 375 horse had hydraulic lifters, optional engine shad solid lifters. It's true, and it's OK. https://www.allpar.com/cars/chrysler/300C/300F.html

They are casting #2206324 with 2.08 / 1.60 valves. Looks like when they did the valve job they installed new TRW exhaust valves and topped them off with aluminum retainers which don't seem to have a great following from what I've heard. Valve springs were about 140# at 1.750" and about 260# at 1.250". I'll keep you posted as I get into things. Still have the cylinders and lifter bores soaking for disassembly. Fingers crossed it comes apart fairly easily without killing anything.  Also, I did check for plugs in the rocker shafts. They are installed just after the first set of bolts. Good looking out guys.

62 MW blocks, ive seen there are also 2 bosses at the rear of the intake area, look similiar to water pump housing bosses, but of course not open. only HD blocks had those from what im told I've not seen a lot of original 413 M.W. blocks but I'm going to say none of them used the H.D. industrial blocks to start with  I have used a 413 H.D. block to replace a original 413 passenger car block in a original 1962 Dodge M.W. Dart, the original 413 block in that car(not sure if it was the original proper block or not either) was already bored to 4.240 and it did not sonic test well either  I had the 413 H.D. block bored too 4.250 and had Diamond make a set of reverse domed pistons to make 9.4 to 1 compression ratio so the customer could drive it on the street with CA pump swill back a long time ago in the mid 1990s I am using a 1972 413 H.D. truck block in my 1963 Fury to mess with some of the local car show expert crowd     I'll tell them a story like I know what I'm talking about  I'm going to tell them it was a rare factory option police pursuit car or something similar, it has a set of 440 Source heads painted the Mopar green and a 4.150 stroke crankshaft with a little over 10.3 to 1 compression so I'm hoping it will make north of 525 HP
