The official FABO machinist/member collaboration, busted 340 thread

[fishmens67]

If the hijacking doesn't stop, I am gonna be done updating this thread. Its ment to help a guy out, and be instructional, not for random members to argue.

I asked you a question and it got deleted.
Was wondering which direction the build is going?

 

[Confusedcuda]

Sterling and dartindanno. May be in touch with you to work something out. Thank you

 

[Confusedcuda]

Haven’t decide on build yet. Weighing out options still. Thanks

 

[DiggerDart]

Thanks for helping out. Also can't wait to see how bad the crank is. Is the cam wiped?

All that info is in the thread with pictures if you read from the beginning.

 

[ajarofclay]

So this thread will be about a FABO member who bought a previously rebuilt 340, had numerous issues, and the guy who is going to help him out, because we all need help sometimes.

You're a good man, Charlie Brown.

Not a lot of progress, but that horribly filthy block is now clean!

Just out of interest, what are you using to clean those heads and block?

Depends, but on this one, it was done in a ampro thermal cleaning system.

Yes sir, clean bill of health thankfully!

Well, after cleaning the block, we decided to run a hone through the bores real quick to see if it will clean up with a additional .010...(at .030 over currently) . I am not sure you can see in the close up picture, but all the bores are heavily pitted, I dont have much confidence in ending up at .040 over with a nice bore. Looks like perhaps .060 to clean up. Very obviously a rusted up old .030 over block just honed when last "rebuilt"

Would Sleeves would do the trick and keep it a standard bore?

Yeah but it would be over $1000 to do all 8

 

[replicaracer43]

Sonic check before ordering pistons

Yeah no ****.

@replicaracer43 Has the owner decided what to do or where to go with the build?

@replicaracer43 Has the owner decided what to do or where to go with the build?

I believe he is staying on the mild side, stock stroke, X heads, small hyd roller cam. More "cruiser" than "bruiser"

 

[dartindanno]

@replicaracer43 here is the crank and rods I'm offering for the build. The journals have a couple nicks, let me know if it's something you can use

 

[replicaracer43]

Is it currently std?

 

[dartindanno]

I will take some measurements of the journals tonight. Engine looked untouched but you know how that goes

 

[Confusedcuda]

Thanks

Those nicks look like rod bolt thread marks.

 

[MOPAROFFICIAL]

The donor crank should grind ok if it isnt .020 already...even then...but, of course whos standard/expectation are we going by 'so to speak'. A cast crank would be fine. Stock 70's truck or scat. Only adds to the balancing part if using a 318 base crank.
Good going on helping this guy.

 

[dartindanno]

The crank journals are standard size and hopefully those 2 nicks can be cleaned up.

 

[65 Dartman]

I have a crank out of a 72 truck Std Std I think including the balancer I’d be willing to donate
