I did the same almost 10 years ago, I used Clevitte 77 bearings that they are not manufactured anymore, you can only find bearings made in ISRAEL. I also used SS valves w/ hardened seats, HV oil pump, double roller chain, grade 2 camshaft, new lifters with adjustable push-rods, 10-10 fresh crank, new freeze plugs, Molly rings with Fel-Pro Gaskets. It was an expensive endeavor...

Sounds good. I picked up on "carbs". So going for horsepower then? Man that is a serious looking crankshaft, I would like to do one of these engines, but not feasable here in Australia due to shipping costs.

What kind of rear main do they run? Like the early 413's?

Keen to see the work you do in pics though, thanks for posting.

You Assies should fill a container 40 'X 8' x 8'. Buy a car and load it up! Should be cheaper than shipping each part by its self.

I have never been called that before!

You are right though, filling up a container and shipping it across is the way to go to beat the postal services rip off prices.

My opinion, FWIW, avoid grinding the crank if at all possible...it's only standard one time. Hot-tanking and polishing is frequently all that's needed.

King bearings are from Israel but good. hemi hot heads prices are pretty reasonable.

Im going for minor hp gain, maybe 30-50 gain over stock.

black valve or gold with polished wire covers?

Hah I guess they are finned for heat dissapation?

Gold covers look great if accompanied by the gold dual air cleaners. I can't say I care for the Offenhouser wire covers, but the nice thing about them is you could use a bigger wire with them. The originals are pretty much limited to 7mm.

Block is ready, final parts to get the bottom bolted up should be here soon. Bearings, rings, timing chain, cover, oil pan, oil pump, freeze plugs, cam accessory kit, dip stick... Got the flex hone in the mail. Ill get the heads done in the spring, I will slap it together before winter hits.

I went with the hot head hemi that's already converted to handle any issues.

Slapping the bottom end together to get it buttoned up for winter. These engines are works of art.

What is this motor going into? I'm pretty sure you can't use a rear sump on any car after 1956.

Stock replacement for a 331 or 354 in a '55-'56, yes. Stock replacement for a 392, no. Like I said, what are you putting this motor into? Most '57-up cars must have a front sump pan, and there are no reproductions of it.

I purchased the same oil pan for my '56 Imperial with 354 Hemi. Oil pan fit the car, but the problem I had was with the drain plug. Once the transmission is mated to the block you can't remove the plug as it is too close to the factory transmission spacer plate. Check it out now before you drop the motor into your car.

That's the 1 we were talking about. replacement shaft isn't hardend & there have been complaints. 392s come with center sump pans, by the way.

the hot head hemi's are the bad ones? I can return.  The "Plan" is t put into a 57 Dodge Royal.

I guess I could return the pan but I really don't have a choice and I can cut and weld the front cross member(I saw an example of this before). The motor mounts will work right?

I heard I do and don't have to cut the heater box? Which is true? I haven't fit it up yet obviously and I know its not just a 'slam dunk".

I will be putting aftermarket power brakes, and power steering.  I can get a "slim" power brake booster but power steering isn't an issue is it?  Does the stock power brakes work? I have 57 and 58.

It would be nice to keep this year correct engine, worst case I can sell this and totally rebuild the 325

I think that's an awesome project, and I encourage you to continue with the 392 install. I don't know about the heater box, but the motor will drop right into the original mounts because I believe the ear-to-ear spacing is the same on Dodge and Chrysler at 17.75" between the top bolts. The only question on the motor position is if you will have enough clearance on the right side of the car. Oftentimes, the original mount position puts the motor too close to the right, but I thought that the Dodge engine bay was big enough to handle the hemi motor in the original location. It would be worth doing a trial fit, but I doubt that you would have any issues there. But you will want to do a trial fit to ensure that the exhaust manifolds are going to fit, if that is your plan.

The stock power brakes will fit fine, but a dual port master gets pretty tight. A remote reservoir will help because the masters for those are skinnier. Worst case, you can use an offset bracket to locate a remote reservoir off to the left a little bit. But the stock master shouldn't have any issue. The original booster clears great because it sits so high. I would just use that.

But...GET RID OF THAT PAN. Don't go cutting stuff that doesn't need to be cut. Just get the right pan in there. That means that you will need a different pump to work with the front sump too. I can sell you a pan if you can't find one, but they sell on Ebay all the time. Very few of the '57-'58 Chryslers survived over the years, but every single motor and their parts are still out there, so they are plentiful. For a performance build, you will want to weld in a good baffle into the pan to prevent oil loss during acceleration.

There is very little parts interchange between the Dodge and Chrysler engines, however, the oil pump happens to be one...
The Melling M50 pump is available everywhere. Parts houses, ebay, Amazon.....everywhere. 100% bolt-in. No adapters. No special pieces/parts.
The 325 pan should have the same center-sump design as the usual 392 pan so the pick-up tube assembly should work. Double check it.

Should be 392 center sump pans on E Bay, or check the HH Classifieds, HAMB classifieds, ect. Your 325 pan won't fit. I'd send the HH O/P back, where the M-50 is available. Why risk it? When I put a 331 in my '60 Plym I had to delete the heater box & put in a piece of sheet metal. Non power M/C fit just above the valve covers, the 392 has a higher deck height so it will be a bit tighter. 331 fits like it belongs there.

I know a 354 poly will fit with the 325 mount brackets but it is awfull tight to the heater box. Remember that CDN built 58 Dodge CR came with 354 but used special motor mounts that moved the engine forward I little. I used to know how much but can't remember. These are the same mounts used in 501s. There will be pics of 501 hemis to show the master cylinder to hemi head clearance. I can send pics of my 354 poly clearance with MC.

I may be able to find pics of a 392 in a 57 Dodge but I think I supplied him with the CDN mounts.

Yes as Greg says the 354 mounts are facing forward , I think you will hit the heater box if you don't alter them? Here are all the pics I have of a 354 in a 58 Dodge , I ended up using a better frame on this one that had originally been fitted with a 350 but ended up cutting the 354 mounts off and welding these in place?
