The Dodge Challenger Message Board

I have a 440 six pak. Casting no 2536430-6.
Engine no OG184751. ID no F440 1110 HP. Dated 6 - 10 - 69. It is all there including AC. The damper is externally balanced and it certainly has 6 pak rods and forged crank. The intake is iron. Intenally everything looks to be in good shape. I can't afford to freshen it up and it has to go, how much is it worth? Ps the Air con is a mod.

I was going to mention that AC thing. How chopped up is the air cleaner, how many miles are on it and what part of the world are you in?

The Ac unit is a lot smaller than an oem ac pump, its Japanese, the brackets look fabbed but its not a bad job, it could be an after market mod. Also the ac clutch is electric. The motor came from a 50,000 mile '68 car so didn't come with this engine. Judging by the wear in the bores I dont think its done too many miles, theres no lip and the cross hatch honing marks are still visible. But I,ve been told these marks can last many thousands of miles. In truth I dont know the milage. Internally its stock and unmolested, I live in the UK by the way.

In fact Tig lives about an hours drive from my place. Is that about right Tig?

Thats right Dave. Know anybody who might be interested in this thing?

Dave, what do you think the shipping to Los Angeles might be?

Also, what is the condition of the air cleaner? Was it cut up to fit the AC or was the unit small enough to leave it untouched?

Jack. I know Tig has shipped engines from the US to here so he should have an idea. But then again it might have come over via a friend of ours who sends a container now and again with a car in it.

Jim Wilson who is a member of this board has shipped many cars and engines over from the US so he would be able to give you an idea too.

Tig.
If you are not an MMA member do you want me to post an ad for you on their message board??

Looks like I have found an interested party here in the UK Tig. I have sent you an e-mail with his mobile number. Sorry Jack.

Nuts! I thought I had the inside track!

You could still have the inside line Jack,... Still open to offers.

Dave-R. Would greatly appreciate you putting an ad on MMA site. I'm open to offers. Do you need an advert formulating?. Thanx. Tig

I will copy what you have here Tig. It will help if you say how complete the engine is. i.e. does it have all the carbs/linkage and does it have the air cleaner? Has the air cleaner been cut for the air con? Does it have the cast iron exhaust manifolds? etc.

Did you get the mobile phone number I sent you?

Any offer would depend on how complete the engine is and what shape the parts are in. More info, please, Tig. Thanks

I was happily surprised when I found a six-pack K-Frame on my U-code R/T SE. I got even happier as I took the car apart and found a six-pack balancer and six-pack connecting rods as well. I'm trying to find out the existing compression ratio. This engine has been rebuilt and the cylinder taper is barely discernable. The pistons are roughly 7 to 9 thousanths below the deck of the block at top dead center. Can anyone out there help me figure this out?

There is a part of my maths spreadsheet that works out compression ratios.

What is the difference between a 440 4bbl k-frame and a six pack version?

The six-pack K-frame has an added skidplate welded to it that protects the deeper oilpan.

I checked out the math sheet and believe that I've got the pistons for a 440 Magnum 4-barrel in the engine right now as the compression ratio seems to be about 9.7 to 1. All things considered - fuel quality and budget, especially - I think I'll stay with them and add six-pack carbueration to it like you did, Dave.

I have that skid plate too.

Did the six pack (or HP2?) engine have a deeper sump (oil pan)? I thought they were the same only of course with the windage tray and extra gasket it would be just slightly deeper??

The Six-pack came with a 7-quart oil pan and a windage tray and it is deeper than a 5-quart oil pan. From what I've been told, many of the U-code 1970 engines were HP2's and that would make them the same inside as a V-code engine and give them the same compression ratio and balancer as well. The presence of a skidplate on a U-code car is common as well from what I've learned today.

I know that Paul Herd has been wrong before. Anyway, this is what he writes about k-frames: Three basic k-members were used: one is for the six-cylinder engines, one is for both the small- and the big-blocks, and the last is for the hemi. T/A is listed as using a special cross-member, yet there is no aparent physical difference between it and a regular k-member. A small, round, metal tag is welded to the bottom of the k-member, and the last two digits of the part number are stamed upside-down in the tag´s face.

Note: He does not mention anything about 440 six pack engines. That makes me a bit uncertain if this engine used the common V8 k-member or the hemi k-member?

Question: This metal tag that he writes about, does it appear on all k-frames or only on the T/A-frame? (I am not quite sure what he means)

Fun to read that you succeeded with the overdrive installation. Maybe we can call you Mr Four-speed from now on?

since a 440 wont bolt to a HEMI k frame.

Casting no 2536430-6. that doesn't mean its a six pack motor.
