Chyrsler 440

[blue88]

I just picked up a 1966 chrysler new yorker 2 door. I am completely new to chyrsler motors......
So, I have a question for all you MOPAR guys.

The motor should have been a C 440 HP.. with either 516 or 906 heads... however, it is an E 440 HP 9 17 (date code?).. making in a 1969 motor with 452 heads and tm7 intake. What kind of horsepower could I expect assuming all the bottom end is stock 69? I think compression may be lowered from the heads... but not up to snuff on all things MOPAR.... just yet.

Thanks in advance.

>>blue, I would ask in the "a bodies only" forum". Lot's of savy mopar motorheads there. Regarding, how much hp?...wide open. You seem to have a hi perf replacement 440 ? Who knows for sure the cam, compression/etc. ? If the harmonic dampener has eccentric weight cast into back side, I'ts likely a "cast" crank, not hiperf. Good Luck, flyingwedge.

Thanks Flying. Being so new to Mopars.. all information is helpful.. Will check the harmonic balancer.

Check what you can on the outside of the motor, like (as has been mentioned) the harmonic balancer, ignition system, exhaust headers. Pull a valve cover and check the casting numbers on the top of the intake runners, look at the rocker arms and valve springs. '69 motors came with 906 heads.

If it has the stock exhaust manifolds, it will be hard to push more than 400hp out of it no matter whats on the inside. You might have gotten lucky, that TM-7 is a good piece.

Exhaust manifolds is stock 66 - 69 stuff by the numbers. The guy I bought it off.. says he has a newer set of manifolds to give me .. since one was cracked from loading/unlaoding from trailer.

[Powertrip]

So what does the guy you bought it from say about it's history?

[blue88]

Well... that was part of the issue. He bought it.. it sat in his garage for 10 years. I do not think he knew much at all about it. It ran when he bought it.... was going to restore.. you know... like most people. Told me the motor was 1966 440. I am new to mopar game.. so I believed. It is a 440.. Just not higher compress 1966... but 1969 bottom end with 76 -78 452 heads. I have not pullled the plugs to put mystery oil in.. and check pistons and go thru all the stuff before trying to start.

[Powertrip]

The 452 heads have the same combustion chamber cc's as the '69 906 heads. The '66 through '71 motors all had an advertised compression ratio of 10:1, unless it was a HP motor. Actual was closer to 9.6:1, plenty for iron heads, stock cams, and a little oil burning. I would not worry about compression at this point.

[blue88]

Thanks Powertrip....

Block shows E440 HP on tag.. with date 1 17. Does that mean the block is HP motor? And really.. what does that HP mean in terms of internals... etc.

Thanks Magnum!!!!

Finally got it to stay runnning... changed the fuel pump and still had issue.. running it off a can of fuel. So, I replaced the fuel pump rod with a slightly longer one.... 3.245 vs 3.22 worn out won. Runs good now.

Hey blue88,

It looks as though you've got a '69 HP engine. The HP engines typically come with a windage tray, dual valve springs, forged crank, and performance exhaust manifolds... that's the difference between a "standard" 440. Yours should be equipped with the "906" casting heads. The "452" casting is essentially the same, but with hardened valve seats. As a FYI, 440's were not available with a 2bbl carburetor - seeing how you're new to MOPAR engine family that would give you a quick ID as to whether you're looking at a RB vs B engine from 10 ft away. Once you have a hands on look at the big block MOPAR they are easily identifiable.

Thanks Clark. Block and bottom end is 69 HP 440... but exhaust manifolds are 66 new yorker and heads are 78 452... So, I am not sure if this is a rebuilt motor or one that the heads were replaced at some point. Either way, I am going to run the crap out of it...

I prefer the 452 casting cylinder heads.
In stock form, they have a better exhaust port and also the smaller spark plug which will not interfere with headers.
