Title: engine weight
Post by: baxter culver #17184 on January 25, 2006, 02:44:06 PM
Can anyone tell me what the flathead (346 cu in) engine weighs?  Also, the same for the early 331 cu in o/h valve engine?

Thank you Jeff!
This is the kind of response that proves the value of being a member of the CLC and having the resources of so many individual Cadillac/LaSalle owners at hand.

Engine Weight FYI

by Dave Williams
dave.williams@chaos.lrk.ar.us
version 93.11.14

It isnt really a Frequently Asked Question, so Ill call it an FYI,
For
Your Information. This was originally a list Id compiled long ago on
paper, then moved to the computer, then posted on the net as a response
to
some questions. It wound up being popular, but since I didnt keep track
of
the origin of the data there was some debate as to how accurate the list
was. This new improved list has origins where I could find references;
what
doesnt have an origin is stuff from my original list.

Youll sometimes see more than one weight listed. Some weights are for
just
a long block, some are complete and ready to run, and of course
everything
in between. Some engines varied in weight during their production runs -
for example, some later Chevy V8s use thinwall blocks and aluminum
heads.

If you have any figures youd like to contribute, please send them to me
at
the email address above.
