QK code 409?

[Carl 1962]

This engine is for sale on Facebook Marketplace for $1,900, but I've never heard of a QK suffix code, and do the dipsticks always angle like that?

 

[La Hot Rods]

That looks like it had a serious crack repair.

Not worth that as it's a cracked truck block

I also never heard of a QK and couldn't find it any where.

I think the dipstick angle is about the same as mine.

That block has no notch. Interesting.

Marine engine?

 

[DaveN]

Wonder if the head surface is warped with all that welding doesn't look good. If I was selling it I would make it more presentable at least. my 068 marine block doesn't have any stamping on the pad.

Marine engine?

That's what I was thinking,didn't Dayton have a 400 horse marine 409?That wouldn't have been based on the truck 409 like the other marine engines would it?

 

[IMBVSUR?]

Any chance this block was machined and the numbers were cut off and someone screwed up on the re-stamp? Just curious. I have no idea and can't find anything also so now looking at alternatives.

All I need to see is Q, what comes after that doesn't matter much.

Q only means 409 before 65. 65 is a J. His may be a replacement or over the counter block. I'm not familiar with that code.

What’s the price of iron ,

 

[427John]

While the price is out of the range I would pay for it, if it magnafluxed and pressure tested good I wouldn't hesitate to use it. It obviously was used in an application that used center dump exhaust manifolds due to the heavy sooting from a long term exhaust leak. As far as the ugliness of the repair, form follows function.

 

[64ss409]

There were 348's used in some farm equipment, forage harvesters, etc. I think New Holland was one that used them. Maybe this 409 came from farm equipment? Since Tonawanda stamped it, I think it was purpose built for something. The over the counter replacement blocks/engines I've seen had no stamp.

Form does follow function but there is another saying. A pretty weld can still be weak but an ugly one always is. I would question whether it would crack again in the future. Cast is funny that way.

Looks like a grind out and restamp to me. Maybe it was supposed to be QR which would be Pg and transistor ignition. Whoever restamped it misstook the R for a K.?

It is a 068 block.

 

[Carmine]

Looks like a serious crack repair to me. I've often wondered, with a cracked block, metal separates and you have a visible crack. At least I think that's what happens. So, with this separation, does anything become misaligned some, like pistons in the bore or maybe bolt holes?? There has to be movement somewhere I would think, Carmine.

 

[oldskydog]

It is a 068 block.

Oops, you're right. no 340hp in 62.
