Thanks Mac. I pulled the following off the Stovebolt page...it helps, as
does your figures and info...except for the fact that Stovebolts info has
the firing order wrong...should be 153624 (not 153642).
BUT, what I'm wondering: is the sequence based on the author thinking he had
the firing order right and hence the sequence is really wrong based on that,
OR, is the firing order simply a typo, and the sequence correct and based on
the truely correct firing order (ie. the sequence listed below is right, and
that the only thing wrong is the firing order TYPO)? Can anyone tell me if
the sequence as posted, is correct to use?
TIA,
Rob
Cut and paste from Stovebolt page:
#3 General (Engine NOT running) -- "I have a trick I use every day at
work to set valves on inline 6 cyl. motors. Chevrolet and John Deere firing
orders are the same: 153642. Set the motor to fire on #1. Set the lash on
1E, 1I, 2I, 3E, 4I and 5E. Then rotate crankshaft one revolution. #6 should
be in firing position. Set lash on #6E, 6I, 5I, 4E, 3I, 2E. Your valves are
all set, and it only took about 5 or 10 minutes. Remember exhaust valves are
on the ends of the head, and they look different than intake valves, so it
is easy to identify the valves for cyls. 2,3,4,5. I hope this will help
someone. Again, thank you!"

Hi All!
This is in answer to Rob's question regarding the setting of the valves
when
cold on his 235. I have consulted my faithful Motors Manual and it says
as
follows:
Year 1953 Intake .006 Exhaust .013
1954 - 55 Intake .006 Exhaust .016
1958 - 59 Intake .006 Exhaust .018
1960 - 61 Intake .006 Exhaust .018
These measurements are based on a HOT engine. A HOT engine is one that is
normalized. By the book this means an engine that has run for at least 30
minutes so that all components have reached their normal operating
temperature. If you want to cold set your valves add about .005" to each
measurement then let the engine come up to temperature and reset them to
the
above identified numbers. There is no numbers in the book for years 1956
and 57 as is would appear that the valve system used hydraulic lifters and
not solids.
Hope this helps
Mac
