    Hey:

    Been on the hunt for a big block for a while.

    Came across a low mile standard bore carb to pan 69 440 out of a GTX. Dude says it runs good.

    Is this going to have decent compression and what-not? Would the pistons be a mile down in the hole? Are the heads on this thing any good?

    Thanks!

    Steve

      Thanks. That sounds about as good as it gets!

      I know just enough about big blocks to be dangerous, which of course is why I want to start tinkering with one!

      It's one of the better ones you can start with, yes. Actual comrpession is closer to 9.5:1, pistons should be down in the bores a little (.040-.060 IIRC), but a foged crank, 906 heads, and decent intake.

      It better have "HP" on the engine pad or most likely it's not a 906 headed, high compression 440.

      That's in front of the intake right? To the right of the dizzy?

      I'll be checking that.

      In the front to the right side of the thermostat. It will have a raised square with the numbers stamped on it.

      69 440 are one of the best 440s.especially a hp. all 440s form 68-70 had 906 heads & the good high compression pistons.it was the cam that was different.

      X10, just make sure you check the date code and head casting numbers in case someone did the switch-a-roo.

      Itsa good one as long as YOU can hear it run. I got a 69 440 6-pack engine that I just pulled from my Cuda. Had less than 2500 miles on it. The prior owner jacked with the center carb on the sixpack and crack the mainbody and it poured fuel into the intake everytime he drove it. Well, I pulled it suspecting the rings were washed cause of excessive smoke. I needed the 906 heads on my turbo 400 and when I pulled them that is when I confirmed that the rings were washed. Guess it will need a re-hone and fresh rings and bearings.

      Sooo, be sure you here it run before you purchase it. Anyone can crank a engine on the floor!!

      This is an excerpt from 440source.com concerning HP blocks. Interesting.

      There is absolutely no physical difference between a block with an HP or HP2 stamp and one without.

      All blocks were cast and machined at the foundry, and then assembled at Chrysler's 2.1 million square foot "Trenton" assembly plant in Trenton, Michigan. During assembly, if the engine was given high performance cam and valve springs, or in some cases other items that differed between HP and non-HP engines such as: six pack rods, carbs, etc., then the engines ID pad would be stamped with HP. All blocks originally came from the same place, and there is absolutely no difference in cylinder wall thickness, nickel content in the cast iron, strengthening ribs on side of the block by the freeze plugs (see below for the real story on this,) or any of the other myths you have heard. The number 2, which you may find after the HP, (or in the case of non HP blocks, you may find just a "2" by itself, usually in the lower right hand corner of the ID pad) refers to the shift during which the engine was assembled. In running a factory, one 24 hour day can be divided into three 8 hour shifts. The first shift was considered a "1" however to save time, Chrysler did not stamp a "1", they just left it blank. So an HP2 engine, only means that the engine happened to be assembled on the second shift. There is no advantage to an HP2 block over an HP. we have never seen an HP3, (or just a "3") although Chrysler does allow for it in their documentation, so let me know if you have one or have seen one. Also of note is that non-HP engines usually used the same heads, intake manifold, and many other parts, which is great since it makes it a lot easier to bring a non-HP engine up to the power levels of a factory HP and beyond. But unless you are doing an original restoration, don't worry about finding and/or paying extra for an HP block.

      You can also check to see if it has a forged crank in it by the balancer.

      It had a forged crank, no HP on the pad. Did have 906 heads, no exhaust manifolds. Had the oil pan that is good for swapping big blocks in A-bodies rather than the one with the baffles (its too late for me to remember the numbers)

      Carb was from a 69 340.

      I passed on it.

      Thanks for the help guys

      I didn't hear it run. He was asking $950 carb to pan, with accessories and pullies, no exhaust manifolds.

      I don;t think he was trying to pull anything over on me, I honestly think he didn't know it wasn't an hp. Just pulled it out of a '69 GTX and that was what they were supposed to have.

      yeah, that's strong money for a std 440.

      Sounds like it original came out of a C-body.

      That engine would be great to go back in a 69 GTX if that is what it came out of. On the passenger side of the engine just above the oil pan there should be some identification stamped in the block. I have seen the VIN prefix stamped on some of those engines so it would start with a RS if out of a GTX. It may only include the last part of the VIN but worth checking. Check out the cars we are working on with Face Book, Dirt Dobber Classics.
