440 engines in the 74 model year.

[commando1]

The last word, did any big blocks with steel cranks go into any 1974 model year passenger vehicles or pickups?

 

[1978 NYB]

Not that I'm aware of.....all cast cranks.

 

[Fratzog]

Also my understanding. Cast cranks from 72 onwards.

From the 74 parts book

 

[Fratzog]

Stand corrected. Learn something new here all the time.

1974 Pad. No "E" for cast crank

 

[heyoldguy]

There were many 440 passenger cars in 1973 with forged cranks, and any 400 or 440 with a manual transmission, even into 1978 was supposed to come with a forged crank

Forged cranks were standard in all 440 magnum engines thru 1974.I presently have one, from a 1974 Charger Rallye 440 magnum car. In addition, the crank was drilled for a manual transmission, and according to a very good Mopar Buddy, some manuals were built in 1974, despite the numbers saying none were built. I believe Chrysler was using up their supply of 440 engines, as by 1978 Iaccoca destroyed everything related to the 440.

Of my two '73 440's, one is steel crank, the other is cast.

All manual trans and 70 up to 74 HP have "6 pack rods" which were also in motor home 440s of this time should have the special vibration dampener, not the cast crank one. I'm sure there are standard rod engines out there also.

 

[1978 NYB]

I have the 1974 Chrysler/Imperial Data Book.

Drop-forged steel or cast ductile iron on all engines.

 

[moper]

The last word - Yes.

That is true, as I have a 73' 400 here as well with a forged crank, drilled for Manual transmission.

I believe Chrysler had 440 blocks, cranks, heads, etc., available through 1984 even though none were produced beyond 1978. I believe 440's were installed in motor homes up to 1984 too, but again all of those engines were produced prior to 1978.

Yes, 'tis true. Same for the AMC 401; made through '75 but could be found in Wagoneers through '78.

My question, and something I have never understood: What's the difference between forged and cast? Seriously, don't know. What would my '71 440 motor have?

 

[commando1]

You have the Forged Steel crank.
A forged piece is stronger than a cast piece because of grain alignment and all that metallurgy crap.

But the BB cast crank is unfairly maligned. Even stock, it's good for 600hp easily without a whimper.

Thanks Stan!

Cast is molten iron poured into a sand mold then machined to work in a engine.
Forged is steel that is cast into a workable shape then worked (forged) while still hot into a crankshaft shape, cooled and then machined to fit in the engine.
