Re: IML: 354 Hemi Industrial



Hello,

Hanks Dozier, from Forwardlook.net, passed this on when I forwarded your
question to him.

I hope it is helpful.

Pass this back to these guys....

An industrial 354 will certainly fit, and may make a good replacement
engine.
That said, there are a few potential differences that may have to be
accomodated, especially if you want to swap in a 4bbl manifold.

The Industrial engines for the most part kept the iron timing covers of the
early 51-54 331s.  As such, these covers are more bulky, and the cam in the
engine had a longer snout than the 55-up 331/354 and the 392s.  It is still
possible that your engine has the passenger stamped cover, being a late
Industrial motor.

Another issue was the heads.  Industrial engines had the water outlet in the
intake manifolds, IIRC, so the heads did not have the outlet passages for
the thermostat manifold lke the 55 and up engines.  If this is your case,
then the only 4bbl you can use is the rare 1954 331 4bbl unit that had this
feature.

Also, some Industrial engines used water-cooled intakes, so if that is the
case, then your manifold IS limited to the type you have.  Or you shop
around and get passenger car cylinder heads (they are available, just be
prepared to pay the going rate).

As it is an Industrial engine, you MIGHT have one with solid lifters.  Look
for "bumps" in the valve covers.  But before you think you have found the
gold mine, pull a cover and look beneath, as those bumped valve covers were
also used on some engines that had hydraulic non-adjustable rocker arms.

IF you have solid lifter adjustable rocker arms, you can most likely trade
them and the pushrods to someone for a set of hydraulic rocker assemblies
AND a set of passenger car heads, including hydraulic pushrods.  Stay away
from early heads.  Get ones for 1955-56 331 or 354, and find the modern
water pump assembly setup!  You will need to get a new hydraulic cam at this
point, but those you can buy from several sources (PAW, Hot Heads,
Schneider, Howard, Neilson, Crane for starters) along with a lifter set.

The engine as is can mate to the Powerflite.  The 4bbl is a more visually
appealing piece, and is a simpler unit to work with, as the dual-single carb
units were all low-end grunt.  But until you find the other pieces, its a
start, and can bolt in.
