Searching for a few parts that were missing or damaged on my newly acquired '69 340. Any years that will fit it is fine by me.

Here's the list...

Internal:
pushrods (I read the originals were shotpeened and different from other sb motors)
timing chain oil slinger
oil pump intermediate shaft and bushing

External:
damper / harmonic balancer
air breather
throttle brackets/linkages (that will fit over an LD340?) I have 318 brackets.
throttle return spring (black 2946695 is supposedly "correct")
valve covers (I'm thinking the cast Mopar Performance look sexy )
dipstick and tube


Thank you for looking.

That does help, jimynick.   

My bet is the balancer and pushrods are going to be the biggest challenge/expense.

Any recommendations on the better parts? I've seen plenty of junk parts that I won't put in it. My goal is a trouble free engine with some oomph! But I also don't want to break the bank. It's been about a decade since my last engine build and I don't remember quality parts/suppliers vs the junk.


Thanks!

Completely dependent on what you are looking for. I know you posted a list and if that is all, Mopar performance damper would be a decent choice. As to the push rods Mopar Performance, Comp, etc. Sure there are junk parts out there but there are a lot of good ones as well. Older isnt necessarily better. I really do not think I would use 48 year old push rods in a new engine unless that is all I had and it was a very stock engine. If you are building any HP, I would definitely be using new push rods.

I think I have the push rods. I have a lot of 340 parts, some from a new rebuild that the previous re-builder left a piece of plastic in the oil pump and sheared the oil pump shaft, so those internals are pretty much new. Cranks, rods, pistons, lifters, cam.....

Thanks guys,

Yea, 70chall440, I agree, old parts in a rebuild probably not the greatest idea. Yea, the 340 had shotpeened pushrods. So I just need something up to par to replace them. I'll have to keep shopping.

Topcat, I don't have the original harmonic balancer. That's handy to know though. I've found different styles from under $100 to more than $400 (quite a range). Again, just looking for something decent quality. MP might be the best way to go.
