There was a 365 HP 426 wedge with a single 4-bbl carb available in Dodge & Plymouth in 64 & 65. I had a 65 Coronet 500 with one. I wouldn’t think a dealer would go to the trouble to “special order” an engine with only a 5 HP rating difference than the standard L engine. Big block engine number pads starting in ‘65 were stamped with the letter “A” before the displacement. The alphabet continued with B for 66, C for 67, etc. If it was a 65 Dodge engine, it would be stamped A426. Not sure what the L engines were stamped in ‘65, a New Yorker would be stamped A413.
Well, there was the max
wedge 426 but it was embellished with dual quads. Boring out a 413 by
1/16” would take it to 426 cubes. Max connections sometimes facilitated
unusual drivetrains but a single 4-BBL 426 may not ever have been
The club, through Cuzzin
Gil Cunningham, has records that can identify the matching numbers for hemi
engines which were each stamped with individual serial numbers. The engine
serial number was recorded on the IBM build card for each letter car
1955-58. Although the engine serial numbers are not as the chassis VIN’s,
the “matching” is to the company build records.
Wedge engines were
identified as letter car engines and stamped with their build date. I’m
not aware, but doubt if, the build date of the engine was ever recorded on the
build card or anywhere else. The engines were no longer serially
I don’t think Gil has
the IBM cards for ‘65’s or ‘70’s.

We can't quite see enough
of the engine to be sure, but it looks like a 413 to me.
Off an allpar site
discussing building a NASCAR motor:
In a 1994 Mopar
Muscle interview, engineer Tom Hoover said, “We knew with the power
level we could expect, we could provide performance and win races for minimum
expenditure. You could continue to hone and evolve the Wedge forward, but the
results would be limited. The cost effective way to make a real impression at
Daytona was to take advantage of the A311 Indy program background, and adapt it
to the race ‘B’ engine.”
When the 426 Hemi was introduced in 1964, it was strictly a racing
engine. On February 23 of that year, four Hemi-powered Mopars swept the Daytona
500, finishing 1-2-3-4. This single event caught the racing world by surprise
and prompted NASCAR to impose stricter production rules on Chrysler. Instead of
producing a few blueprinted Hemi motors each production year, they would have to
produce several thousand and sell them in “ordinary” production vehicles.
Chrysler didn’t throw in the towel on the hemi after this (although they did sit
out the 1965 season), and the end result was the Street Hemi, which first
appeared in 1966 B-body Dodges and Plymouths.
So, per Tom Hoover, none
in 1965 and then only in Dodges and Plymouth's. in 1966 and

wish had a 426 in it...
