I have a block that will need to be sleeved. It is now at 3.860 diameter with no internal damage but has pitting from moisture. What is the best sleeve to use on this block? Thanks 56 VIC.

Just an idea. I looked into sleeving a 312 block and it was pretty expensive. You could use a 292 block and grind down the 312 crank mains.

I you need to sleeve the whole block, then you're probably better of to simply find another block. It's about $150 a hole in my area ($1200 for an entire V8!). Another option is to check the wall thickness to see if it can be bored further and order some custom pistons for the large bore.

I rebuilt a Chevy 409 and bored it .080 without any problem. Check to see if this is a possibility with the 312. Egge Machine makes the pistons in .080 for about $325.00

Sleeving one cylinder? How bad is the pitting! Anyway, if boring a 312 .080 over, cylinder wall sonic testing is definatley recommended. Otherwise, if the block has core shift,you might be throwing your money away.

I did not know you could get .080 pistons for this block. I just can not bring myself to give up on this block. I live in Western Ky. and have not found a shop that does sonic testing in my area. I may have to take it to Nashville, Tenn. to check wall thickness and for cracks. Only #8 cyclinder would hone out. The worst cylinder is #5. I think .085 over would take care of #5. However I still may go with sleeving the complete block back to 3.800 then the life of the block would be extended a lot. Back to my original question concerning sleeves? One shop owner said he uses a sleeve that wedges in the bottom of the bore or something to that effect. I think the sleeves that have a lip on top of the sleeve may be a better way to go? If I am going to pay $1200.00 plus the sleeves, I want the best option. Thanks for the info and any comments on sleeves would be appreciated.  56 Vic.

Vic, where are you located? Check Craigs list for your area. Also engines show up on EBAY often. There is an offer on the forum for a rebuilt Y-Block. Would be cheaper still even with shipping or pickup. Since we don't have block/chassis numbers to match it makes no difference which engine you use. Unless you want to match cubic inches. Chuck
