Location: Houston		I pulled the 354 Spitfire out of my car today and while it was convenient I weighed it. This was the complete engine with no carb but with the front accessories in place. b
The scale is calibrated and can weigh in 1lbs increments. Anyone want to guess the weight?

Those weights "dry" or "wet" (eg: without or with oil and any fluids in the water jackets)?

Officially the 354 hemi, with heavier heads, with the huge P/S pump/generator & other acessories is supposed to be 697 lbs. Would be less with modern P/S pump & Alt & an alloy intake

No, the Dodge is a smaller, shorter length engine. The same source that lists a 354 hemi @ 697 lists the 315/325 hemi @ 611.

If you're talking about the '57 there should be only about 30-50 lbs difference(depending on how much heavier the hemi heads are vs the poly heads) between a 354 Poly & a 392 Hemi.

Location: Houston		I should note that both weights are 700lbs, and the first reaction is to assume the scale is stuck on 700lbs. But not so...just to be sure I tossed a hammer on and it went up 2lbs. It's just a coincidence that the weights are the same.

Iron 440 with aluminum intake 652Lbs.


Not to steal this thread, especially since I have a '57 Saratoga which will retain it's 354 Poly, but I've wondered how close a 440 could be brought to a stock LA engine's weight by using aluminum heads, intake, water pump, water pump housing and replacing the RV-2 A?C compressor with a modern unit.

Note the 354 Hemi does not have a distributor, which is light, but also note the PowerGen alternator is much lighter than the stock generator.

If you use a MoPar 400 you are ahead:

1st. with purchase price.

2nd. A 80 pound difference

3rd not as thirsty

4th. they wind up quicker

5th. higher Re-Line using the same heads - Cam Spec's and Exhaust

****
In 1959 when the 413's were introduced there was writing's that it was slightly more than 100 pounds lighter than all 392's.

Location: Las Vegas, Nevada		Thanks, guys. I was just wondering how much lighter a 440 would be with those changes. No plans to do anything like that. I have a 1972 400, a 1967 440, a 1957 301 and a 1968 318, though the latter is at a friend's house in Wisconsin.

Like I noted above, I'm keeping the factory 354 in my Saratoga and keeping it stock. In fact, I am still looking for a correct generator.

Location: DFW, TX		Here is my mockup 331 with a Hilborn injector and no accessories.

I asked the engine stand, and it said it weighs somewhere between "Oooof" and "Get this thing off of me!"

And yes, I did brace the snout of the crank with a wooden jig. That Chebby engine stand is really distressed.

This is an old picture of the 392 for my '56 Plymouth. It's a lot lighter than you heavy weighters
Aluminum heads -75lbs, Aluminum water pump -15 lbs, Aluminum intake -30lbs. So probably around 600 lbs.
I have a GM CS alternator mounted to it at the moment, but I plan to make it look more like a stock 300D motor. I will have to cut up a stock crossover to add in extra length, fill & paint the "Hot Heads" logos, and mount a powergen alternator to it.

Location: DFW, TX		The injector stacks are 1-11/16, so my plan is to run removable Mikuni 45mm air cleaners with adapters. I don't have the tubes or air cleaners yet, so at this point it's just a hairbrained plan.

Those valve covers are from an old dragster. Someone cut big holes on the ends for breathers, and since it had a supercharger where the valley cover used to go, you can see the oil fill tube they had to add on the other side. They're a little beat up and the chrome is a little rough, but they have character!

Ultimately I want it to look similar to "Suddenly's" engine compartment.

Location: So. Cal		Well it is obviously not a wet intake style, (Danny, the motor you posted is a DeSoto, not a '51-'54 Chrysler) but what confuses me is that the crossover is definitely a 4 leg water pump version used on 354 and 331's. They will not fit on a 392. But upon closer inspection, there is something really strange going on because underneath the crossover are block-off plates. It looks like he has the pump spaced out and fitted to the 392 (or whatever it is) with some adapters or something. Very odd. So it probably is a 392, or otherwise, it wouldn't need to be adapted. But why use this pump on it???

Those adapters may be something used to adapt 331/354 heads to a 392 block. I looked for other photos but didn't see many, and none that show detail in this area. The engine is a 13.8:1 414ci 392, so it should get down the road pretty good!

Location: So. Cal		I think I just figured it out. It looks like they were concerned with the water flow through the heads for some reason. So they blocked off the water ports at the front of the heads and are using those two braided hoses to plumb the water from the back of the heads to the crossover. Maybe this ensured that the water wouldn't bypass the heads under extreme conditions and create a hot spot at the back. They probably used the 331 pump just because being offset from the proper screw location, made it easier to block it off with a plate. Or maybe they liked the arrangement better than the separate pump?
