Sleeving a block for strength #1674472 09/20/14 01:13 PM 09/20/14 01:13 PM

However a couple of the cylinder bores show corrosion and would need sleeved. The block has been rough bored to 4.370- Is that too thin for block strength? What if I had all 8 sleeved? Would this make a block that was super tough both on the bottom end as well as the cylinder bores? I am not very familiar with sleeving so I thought I would ask the mopar community. With mega block prices heading into the stupid zone would this setup be a good alternative? Thanks Moparts!

The original bore in those blocks was 4.340", so you should be ok if you hone to 4.375" if that would clean your worst looking bore up. Sonic check all the bores for thickness before investing a lot of time and money in it, you may be able to go farther than that if you need to.

That is the drawback to this block, everything else is okay, but it will need 8 sleeves. Is this foolhardy or something that will actually help the strength? I know that everyone will say move to an aftermarket block but the prices are just ridiculous and it ticks me off to see what people want for them.

I'd sonic that block first, I know of one B-1/230 block deal that was at 4.400" bore.

If It will not go out far enough, are sleeves acceptable or will they a bad idea? I am not worried about spending some money- in fact if sleeves will make the block stronger I would want to do that.

Everything else on the block will move around when you install 8 sleeves so be prepared for a big bill from the machine shop. Everything will have to be checked and many surfaces will need to be touched up.

Its been a while since I had that work done I think Darton was the maker of them back then IHTHs The standard non ductile iron sleeves would pit and rust through from the water side on the drag race only motors back in the day using straight faucet water, you might get 1 to 2 years out of them back then before they would fail like that The ductile iron sleeves never rusted through on any motors I heard of after being switch to the ductile iron sleeves Mr.Cab Racing and winning with Mopars since 1964.

I do believe I will be buying this block, as it has been magnafluxed, sonic checked, cleaned and so on. I will be looking into some ductile iron sleeves and seeing what can be done. I have been wanting a 230 block for quite some time and it looks like this may be the one. I have checked that it has the good main webbing so I think it will be a good one! Thanks again Moparts!

I did a post on YellowBullet about this subject about a year ago and got some real good feedback. In a nutshell; 1)Use the 'good' sleeves I think Melling offers 2 different versions and they're priced reasonable. 2)If you decide sleeve all 8, fit the sleeve O.D. to maintain maximum integrity (wall thickness) in the block foundation. If you 'go big' and bore thru the factory casting, the block will be compromised in strength. 3) Choose a shop that's had a good proven track record for this process. I'm not saying there is only one way to do this. On that 'thread' a couple shops that had success in the process had disagreed on the best method.

I have been looking for a while and just found out he is selling. Now the big question is what do I build out of it? LOL

Sleeping 8 bores isn't for the faint of heart budget wise. You still have a stock block in the end. If your hoping sleeping makes the stock block a better block, we'll, maybe to a certain point. I may have missed it,asI I'll admit I don't read every response. What does this motor NEED to do ? RIP Monte Smith Your work is a reflection of yourself, autograph it with quality.

Unless of course i was doing a restoration in that case none of this would be needed. Just buy a aftermarket block it will be cheaper in the long run with room to grow.
