What it is, is another sign of closet Mopar-ness!

And don't you dare ask "What's a DeSoto??"!!

i would have to say ford 5.0l 302 stroked with a cleveland crank to 402 if i remember right with 5.0 injected intake with 30lbhr injectors

Streets posting a picture of a Dodge not a Chevy, WOW!!!
What is CHR comming too.

chevy 283 is a good motor, but I have to say my fav is a the MoPar 440hp magnum, weighted more than regular 440, it had a higher nickle content in the casting made them stronger..

but to straignten a couple of things out

" .......MoPar 440hp magnum, weighted more than regular 440, it had a higher nickle content in the casting made them stronger.. "

I have never seen any reference to high nickle content RB blocks being produced by Chrysler.

The standard 440 (350HP) and the 440 Magnum (375 HP) started out pretty equal with the same block, steel crank and 10.1 compression. The claimed 25 HP gain over the standard 440 was acheived through a hotter cam and better flowing exhaust manifolds. While the exhaust manifolds would have added a few pounds the engines themselves weigh the same.

THE 69 1/2 -71 440 Six-Pack engines (390 HP), which were not refered to as Magnums, would have been slightly heavier due to the heavier rods and counterweighted vibration damper and flexplate (were only talking a few pounds here). Chrysler used up their remaining heavy 6 Pack rods in a few 1970-71 single 4 BBL High Preformance engines (desiginated by a HP stamping on the serial pad and still rated at 375 HP) . Many of these engines ending up in cop cars and were designated as 440 HPs not Magnums.

From 72 it was pretty much down hill for the 440 with lower compression and cast cranks and finally from 76-78 with thin wall casting that are not recommended for more than a .020 overbore.



And yes Bob this is another sign of closet Mopar-ness!

I cannot find where I read that the 440 magnum weighted more due to a high nickel content either. But I do remember reading it some where.. I should have done a little more research and had the facts straight before posting. But I still think the 440 is still a great motor whether it does or doesnt..


Jonney

I continued to look for any coments on the higher nickel content and I found this..


The later-year blocks did have this strengthening rib cast along their sides, which doesn't hurt, but wasn't worth any huge strength increase. We'd heard the '67-72 "HP" blocks were the hot ticket, and we'd also heard about higher-nickel content in '68 blocks. but Dick told us none of this is true...

I was misinformed I do appologize

In my opinion Mopar had the best Muscle cars, 383's, 440's, 440 6 packs, 426 Hemi, it didn't matter, most all of the Mopar muscle gave the most bang for the buck between the 3 Manufactures. Mopar may not have it for versatillity but, for muscle car engines, the Mopar big blocks are best.

Nothing to apologize for, I'm glad you took my post as it was intended just to add a little information.

..........and you have SOOOOOOOOO much company!!

Whats wrong with the lowly 302.It has nodular steel crank forged pistons and conn rods and the (fabled )high nickel content block from the factory..1986 to 90 something .I just read a hotrod article on how they pulled 1 from a junkyard with 100,000 miles .Just simply honed it and replaced the rings and bearings then built it up to 600 ponies then ran it on the dyno with there backs turned of course then proceeded to run it over and over with great pleasure then proceeded to tell how these new 1s hardly wear becuase of the newer metals and so forth .They said it had no discernable ridge at the top and micrometered the cylinders and said there was no readable wear!!!!sounds pretty nice to me!!! Got 1 in the garage right now i am going to turn into a clevor motor or a boss whichever terminology u prefer. as of this new info i recant my previous vote for the straight 6,.

Well since I am older than Streets, I will mention that I have only seen a few Ardum-Fords, mostly in pictures, but for historical signifigance let's hear it for the Duntov brothers who led the way for the Chrysler hemi. Well the flathead block is a bit fragile for 400+ H.P. with those heads running on only three main bearing webs BUT (!!) take a look at a Red Ram Dodge 239 for a five-main copy of the Ardun Ford. You say you can't find an Ardun or a Red Ram Dodge, neither can I so I am building a mild SBC 350 and so far it seems like any part you need is available for a 350 so we can't discount availability, but if it's dreams you want, go back to the '50s Hot Rod issues and take a look at those beautiful elephant flatheads with Ardun heads. Now back to my 350 SBC!
