finally got out there and looked it over REAL good -NO stampings that I can find ,took a pic of the area I thought it would be ahead of the valley pan ,windsheild has 1953 331 written on it, BUT the short bell and sq water p***age crossover suggest to me its something else what ya think ?, I think i made a deal on it this morning.
Look infront of the valley pan there will be numbers first numbers tell you the year. That should help.
Is there a plate down where the bell bolts on behind the drivers side hood? Most industrials have ID there. If I remember IND56 is a 331 and IND56A is a 354.
the one pics shows no stamping #'s ahead of the vally pan, Have to look for that plate if its there. I am wanting a 354, not a 331, so I have to nail this old pig down ;D,Other HAMB'rs know of this truck/motor and are interested, so if its not what I want I'm p***ing it on to them.the only reason I am interested at all is because this is a low milage rebuilt ,if I had to rebuild it I'd p*** on it FAST
My Chrysler book says 51-52 Hemis have the number on the left side of the block below the head, between the first and second cylinders. Maybe it's an early one?
The heads are no earlier than '55, before that there were no water outlets @ front of heads. There should be a casting # between the head & valley pan on p***. side rear, if tab in front of vally pan is blank.
I've got an old industrial beside the garage and it also has no stamping numbers in front of the valley pan, it has a plate rivited (sp) to the block near the bell housing. Is it original to the truck? Or is it someones old (rebuilt) farm equipment bolted into the truck? I ask because some of those Industrials had a cam that will not work past 2800 rpm. This ofcourse is because they were made to run all day at the same speed. Easy to fix that though.
With the motor mounts cast in the block it is newer than '53. especially without an extended housing.
i have a 53 industrail 331 with cast in motor mounts& a short bell housing! mine is stamped in front of the valley pan and has the Id plate on the bell housing.
looks like its not an industrail motor,it has the same timing cover as my car motor .the industrials have a case cover and a extra water port in the block
I've got a pair of industrial 354's and both have the tin timing cover you say they don't have. Yes, they were original. The style of front cover is often, but not always, more an indicator of vintage on the Chryslers.
there are so many variations of the industrial motors over the years, and it's also quite possible since it's been rebuilt that they put later model heads on...honestly I think it's a variation of the 331 industrial with 354 car heads, I can say with a pretty good certainty those are not industrial heads since they don't have the cast in accessory pads on the front for mounting various governors and other junk that was needed for industrial motors...I'm sure they swapped timing covers along with the heads if the block turns out to be an industrial...I dunno...if it's not stamped in front of the valley pan then chances are it is an industrial, so find that ID tag and we can all sleep better...
I was thinking maybe it was just a 354 with industrial valve covers. Is that a possibility? Just thinking.
Even if it turns out to be a 331, its a simple matter to bore it to a 354 , beside it's only 23 inch difference. If it is an industrial motor it will probably be low compression & have a cam that will need changed. New pistons & a cam is nowhere near as costly as a rebuild. If its a good deal ---Grab it !!
If you can, pull one of the valve covers and see if has adjustable rockers... that is if it doesn't have numbers. Check out the bellhousing also. I don't think any 331's, including Industrial motors had water outlets at the front of the heads. Numbers will tell you everything though... if you can find them. Good luck and keep us posted!
heh heh saw that did ya? i wondered how long it would take someone to say somthing about that, It was his son just to keep it w the motor ,we'll get the number's tomorrow or Wed.
I was thinking more along the lines of a reverse rotation motor. Special use for that 1 forward/3 reverse gear transmission he had lying around.....
not all industrials had adjustable rockers either...and I still think those are p***enger car heads...it would be interesting to see what the block turns out to be...I'm surprised at how many people didn't read the original post and keep mentioning rebuilding it or the cost of doing so, it's already rebuilt, so chances are it doesn't have the industrial cam in it...my guess is the guy had a p***enger car motor laying around with a bad block, swapped cam and heads, threw in some rings and gaskets and called it a day...hurry up mike, I didn't sleep worth a damn this afternoon...hahaha
Looks like a dedicated INDUSTRIAL motor in it's original format. I've the same as pulled from a military water pump rig. Mine is a 331 by measurement with 354 p***enger car heads (no sodium filled valves!). It came with the stamped timing cover and p***enger car style water pump. The pump shaft is a bit oversized like the car units used on air conditioned cars. It had a governor controlled 2 bbl and log type exhaust manifolds dumping out both ends. Rockers were hydraulic. Pistons were flat top only with low compression. The cam was the late short snout and suitable for a re-grind. The block casting # is indistinct on the very digit that differentiates the 331 from the 354 castings. I've not had it sonic checked but suspect it's a 354 block which was never finished to size. Can anyone confirm this? Such thick cylinder walls would be great for a blown application.
got the code -alum plate on Blhsng says it all- took a pic + I looked at it here under my photo enlargement program IND-56 which makes it a 331 IND,BUT I think it would work in a car as it has P*** heads and water crossover if I am understanding this right I can't have it too broke so it is up for grabs for anyone else $1200 FIRM to HIS SON, not my deal or Pauls
