Help Identify This 340

[Agent_Orange]

Ok guys, I aquired this 340 a while back and I am now thinking about droppin the mill in my Duster. BUT...i don't know a whole lot when it comes to engines, and was curious if you guys can help me out here. Can anyone look at these pictures and give me any information they can squeeze out of them.

It might be because you have fewer than 25 posts.

If those X-heads are original, it should be a 68, 69 or(maybe) 70. I hope you are not planning on dropping that in as is. Soft plugs not looking so good.

 

[Agent_Orange]

no i'm going to put some $$ in it. i do have a budget and i thought you all could look at the pics and give me some tips on where money is best spent....

Look just above pan rail, pass/filter side under the block drain plug. Flat machined surface, there should be some numbers.

Also on the front of block, drivers side just below the head. More numbers stamped there.

can you tell me what you meen by soft plugs

After rebuilding, consider replacing the Torker intake with a good dual plane - RPM/Air Gap, LD340 or Weiand Stealth/Action Plus for most applications. Those original Torkers are not good intakes.

That should be a forged crank, which is good.

AKA, freeze plugs. The plugs in the block, used for getting the casting sand out.

 

[Agent_Orange]

i didn't see the numbers on the front of the block

 

[Agent_Orange]

are the heads double sprung? and if so, was that factory for x heads

They should be right under the driver side head on the front, stamped in the block.

Those are spring with damper.

Looks to be a 69 block cast on the day shift.

good! we don't want a night shift casting!!! we all know what goes on in a factory at night...hahaha

 

[Agent_Orange]

Bad_Sport, what do those numbers tell us

 

[pishta]

Take some sand paper and wipe away paint grime under driver side right under deck seam to Right of timing chain There is a very light stamping there. 69 340 big valve, score! 6 at end of 340-6 means nothing.

Your block was cast on Aug 10, 1969. That looks like 8-10-69 on the side.

I can't see the first # in front of the "B" on the VIN stamp in post #18 3rd picuture. What is the first digit? 0 or 1? That will tell if it was put into a 70 or 71 model year car.
