[FWDLK] 1959 361 COMMANDO VALVE SIZE QUESTION SOLVED

[eddee <eddee@xxxxxxxxxxxxx>]

Hello List

This will be a bore to most,,SORRY

 

There has been a lingering question as to the valve sizes used in the early 'B' engines.  With the great help of Roger Howard,, and David Agnew and Jim Pennington we now have most of the story for those interested.

ALSO a slew of calls and emails from yours truly!

 

In 1958 the 350 PLYMOUTH G/C  had the 1.95" intakes and 1.60" exhaust valves.

I believe the head part numbers were 1827968 or 1851887  but both were small valve heads.

 

Also in 1958 the 361 DODGE D500 I am fairly certain had the same set up.,,the small valve heads, although I do not have documentation of that.

----------------------------------------------------------------------------------------------

 

IN 1959 the 'HI PERF' MP2 PLYMOUTH with 361engine had head P/N 1944798.

SMALL VALVE HEADS with 1.95 intakes and 1.60 exhausts.  NO doubt about it!!!!  

 

Also in 1959 the 'HI PERF' MD2 MD3 MS1 MS2 MC3 ( I am guessing these are the 383 D500 Dodges and 383 Desoto Adventurers and the 413 300E Chrysler) had head p/n 1859478.

LARGE VALVE HEADS with 2.08 intakes and 1.60 exhausts.

---------------------------------------------------------------------------------------------------

I was told that the CHRYSLER 300 book was in error stating a 1.74" exhaust valve for the 300E

Supposedly the 1.74" exhaust was not seen until 1963

 

ALSO--this means change you 1959 PLYMOUTH SUPPLIMENT,,,it is wrong stating valve sizes for the GOLDEN COMMANDO  361 @  2.08 and 1.74 respectively.  That is what started this .
