Ok so i have been working on a 1959 dodge custom royal lancer 2dr, it was purchased brand new by my grandpa and ive always been told it had a 361 under the hood, aside from the fact the carb got misplaced over the years and replaced with what i have determined to be a Carter 4bbl off a mid 60s 383 mopar, and generator to alternator swap everything else should be stock, curiosity got the best of me and i started marking down numbers and realized the casting # on the block matches with what should be a 350 big block, which they supposedly quit offering after '58, even the original handwritten dealer paper work only shows the 361/383 as V8 options, so i started searching online for more info and looked at the stamping # at the base of distributor which didn't seem to show what others said it should show but what was there was the engine number which matches the original dealer papers, i also grabbed other numbers none of which match up to the lists of casting numbers ive come across. At the end of the day it doesn't really matter but i just want to figure out what engine is actually in this thing, did this thing some how end up with a 350 that wasn't offered or is it simply dodge using up the last of their 350 blocks and boring them out, which with different manufactures over the years ive come across.

BLOCK CASTING NUMBER - 1944929-6
STAMPING PAD AT BASE OF DIST - MC1V-27904C
LEFT EXHAUST MANI - 1739600
RIGHT EXHAUST MANI - 1945546
INTAKE MANI - 1737708

Intake is right:

Block seems right:

the 361/350 are very close. 361 carried on after 1958, The exhaust manifolds would be the same part number. It's a 361.

(the early 383 1959+ was an 'RB' raised block like 413). Low deck 383 (B) started in 1962.
