Hemi question

I've been trying to get this hemi for 10 years now and the guy finaly decided to sell.It is a 354 hemi Industrial. How many HP do you guy figure it Has?

 

Not sure, but Classichemi.com has alot of info

 

Here are some pics

 

In that form around 150 designed to run all day at low rpm's

 

Not to burst your bubble, but you probably don't want an industrial hemi. Hotrodsnguns eluded to it, but those engines are very specific by design and the there are almost no parts for industrial hemi's. You need one out of a car if you want a good hot rod engine.

 

The Hemi was originaly in a sweaper at the airport.

 

i have a 331 industrail,hothemiheads.com have allot of parts for them.

 

what specifics are you talking about?

other than the industrial hemi valve covers and specific industrial hemi components (pulleys, marine reverse drive gears etc), you certainly can run the same cam/heads/intakes that a normal car hemi would use. the marine hemi's crank looks a bit odd on the crank snout but i havent seen anything out of the ordinary. i have had both versions.

 

what plan9 said

 

There is nothing wrong with an industrial Hemi. You were not planning on just dropping it in & running it were you? If so then , yes a passenger car motor would be better. One good thing about an indy motor it will not have been overrevved ( how in the world did I get italics & how do i get rid of them?)

There is a good chance it has solid lifters & adjustable rocker Arms. The heads may have sodium filled exhaust valves, Chrysler ran them in their NASCAR motors in 56 -58 , cooled very well , ran great. Whatever you do DON"T cut one open!! They are easy to spot ,they have a larger stem & a thicker head. I have used the sodium valves on blown motors with nary a problem.
The heads may have a strange rectangular water passage that has to be delt with to use aftermarket intakes, but it can be done.
The cam can be used as a core to be reground, I have never seen anything odd about the crank snout on one but it is possible, Rods & bearings are the same as any other motor. Pistons are probably flat top 7 -8 :1 compression , sometimes used as blower pistons ,if you hold the boost to about 5 lbs they will work fine if you want to supercharge the motor.

 

haha.... as I've always said... "The empty barrel makes the most noise."

 

For the most part, the only Industrial motors you wanna steer clear of are the ones that have a cast front cover rather than stamped steel. Most of the ones that I've seen with the cast cover have a different crank and have the heads everyone refers to as Industrial heads.

 

The Ind. cams are designed for low RPM use. You would need to 1. regrind the cam &, if you want to run a modern timing chain, have the snout @ the front of the cam machined to use a 318/340 timing chain. 2. Buy a new 354 cam. With a "ring" adaptor the 318 chain will fit. Intake If the water crossover that goes under the carb is square any Chr intake should fit. If it's tall & narrow you would need blockoff plates to cover the top, or use OEM intake. Alternative to that: Looks like you got a 51-53 "long tail" motor, replace heads & intake w 54 car parts ( 4V & better valves/ports).

 

There's been a lot of IND cam bashing, but when I was messin with my Industrial a good number of the Hemi guys actually preferred the IND cam.

 

Nothing wrong with industrial hemi's at all. thats what I'm running in my 34, after trashing the intake and all the weird stuff mounted on the motor its the same as a pass. car . Mine come out of a tug at the local airport, I feel lucky to have it , imagine all the guys who seen that motor in that thing through the years and wanted dibs on it when they retired it. so instead of getting melted down for scrap its resting snugly between the rails of a 34 ford.....imagine that.

 

what is a longtail motor thatsomebody mention?

 

It's got an extended bellhousing made on to the back of the block, similar to the Olds/Cad.

 

Part of the bellhousing is cast in the block.

 

I actually prefer the industrial / marine heads.. the ones I have experience with are cast without exhaust crossovers.. This smooths out the exhaust port flow in the center cylinders.. I use blank cast iron guides so that I can replace the 7/16 diameter sodium filled exhaust valves with a 3/8 or 11/32 stemmed valve. The 7/16 valve is fine, it is just too damn heavy. You have to use a LOT more valve spring to control the heavy valve at higher rpms. That stresses the rest of the valvetrain... There is a good chance that the heads on an industrial have been replaced w/ automotive heads at some point in time if they have been used hard and not maintained.. I've bought several 354 ind. motors, and most have had automotive heads. Installed during a rebuild some time in their past I suppose....

 

I've been dreamin of a hemi for a while now and I keep seeing ind hemi's go on ebay relatively cheap. A few were running on propane, should these be avoided or can they still be used?

 

A lot of cars in Australia have been converted to dual fuel. Way prices are here there seems to be some interest in it.

 

Or flathead Ford, limits/makes more expensive your choice of trannys.

 

I got a spare motor with it and there identical, 56d on the data plate
the part # on the spare block head (1677441) is automotive and the bell hosing is removable I have it apart.

 

The head # is for a 56 354. There should be a casting# on pass. side rear between the head & valley cover.
