Re: IML: 354 Hemi Industrial

Usually this refers to how long (in degrees) the valves are open. Thus it would be a short duration cam and not engine. Short duration is usually lower performance.

Pardon my ignorance, but I'm curious to know what it means for an engine to have "small duration" as referred to by Roger and/or Gabby. Am I correct in assuming it has something to do with reduced time for a full eight cyinder rotation because of the shorter stroke?

If I had the time and the money, I'd take an automechanics and body work class at the local tech school. This stuff fascinates me.

Thanks and Merry Christmas everybody!

Hola And Ah Ho Ho Ho Anthony

I do not have a bag of answers for ya. I wish I did.

In general opinions here, the Industrial engine should hook and pull the car. With the dual carbs, it may perform as the 4 bbl unit from idle to Free Way speed. Due to the smaller carbs and the weight of the car it may not do to good on top end going up to Einsenhower Tunnel Pulling above a 23' AirStream Trailer ( +25', +27'+ etc larger sizes ).

This engine may have a small duration and a very low lift cam due to it's design.

Subject: IML: 354 Hemi Industrial

Hi Everyone;

I have a unique situation. My son purchased a 1956 Imperial, it is a decent
car with a very nice interior. It sat in a garage for the last 20 years.
The one thing missing is an engine. Someone carefully removed the engine
with great care, left everything else intact.

I have just started looking for an engine for it. A gentleman close to me
has a 1957 Industrial Hemi with 39,000 miles. It is set up with 2 single
barrel carburetors, which I would change out for a 4 bbl set up. From my
research, the industrial Hemi has lower compression and hardened valve
seats for low maintenance. The horsepower rating on a Industrial Hemi is
218HP. The 354 Hemi that was in the 56 Imperial has a 280hp rating.

My question is this:

My sons Imperial has the 2 speed powerflite transmission in it. If we use
this Hemi would it have enough oomph to get it around especially pulling
hills? Also when they state an industrial Hemi at 218hp, is it with a 2
single barrel setup, if so how much more horsepower, if any, would adding
the 4 bbl carburetor on it.

Thanks

Anthony
