Is a 1972 340 block worth anything?
Hey guys,
I have a 1972 340 block that needs a sleeve in one cylinder and will have to end up at .060" overbore. Is this thing worth keeping around or should I put it in the scrap bin ? I don't know how the wall thickness is on these things and if a 72 block is anything that restoration guys would be interested in. I can borrow a sonic tester and check it if it might be worth something. Any thoughts ? |
Not sure what it would be worth. But I'm sure someone would re-sleeve it and could use it if they had some spare parts laying around. I know I would.
See you at the Races !!!! :) |
Do not scrap, post for sale on For A Bodies Only forum and you will get a buyer.

I am going to sonic test it and see how thick the cylinder walls are. If they are ok I might go ahead and put the sleeve in it and finish it. All I would have invested is my time and the price of the sleeve. I think it would sell a lot easier as a ready to run deal :) |
I would not bore the cylinders this should be done to the pistons. It also gives the option of 40 over as apposed to 60. You might bore the sleeve to the rest of the block but don't go farther. I wouldn't want a block that was bored ready for pistons.

I always prefer to have the piston in hand but in this day and age it really is not necessary except for special applications. |
My shop won't bore a block with out the pistons for the reason I've stated, I'm going to ask them about it.

Pistons have always been manufactured to fit in a stock bore size or standard oversizes. The clearance is machined into the piston. Some engine builders might want to run more or less clearance for very specific combinations but in general if you finish the bore to the correct size it will be fine. |
I think those blocks are thick enough in the web and bore to be able to even sleeve it back down to a stock bore size if needed. It sounds like it is seasoned enough to be squared up and would do someone a really nice engine. Make a nice little 10.5.1 CR with some J-Heads or Edelbrock heads..
