Tore down a stuck 455 olds, found this in the #8 hole. Can it be sleeved, or would a different block be worth it in the end? The crank has a groove in it too.
My dad sleeved his Ford FE block when the bottom half of the cylinder got blown out. Dropped a valve, split the piston in half and wrapped the rod around the crank. He still uses the crank and the block.
I've sleeved many blocks without ANY trouble...389 Pontiac, 427 Ford (seven sleeves!), 354 Hemi (four sleeves), 351C Ford... and others. The crank can be welded and reground... Do it.
How much can you pick another short block up for, and weigh that against the cost of a sleeve and crank repair.
It appears to be good other than that cylinder and looks to me a good one to sleeve. I installed sleeves in worse looking blocks than that one.
If a crack goes "around the corner" past the sleeve it will leak. A good 455 block can't be all that hard to find. I've sleeved engines that were scored badly, but if there's a hole you're better off to keep looking. A rare or expensive block is another story.
I can't even get a stupid offer on the Olds 455 I saved and guys are going to the trouble to sleeve blocks on their motors? They aren't common, but I bet you can find a car with one that runs for under $1000, or a dead one for less. Sell the body to a demo derby guy if it's a big 98 or whatever.
Rod bearing got loose, the piston blew out the bottom half and the wrist pin beat on the cylinder. I can pick up another runner no problem, but they don't make these anymore. I would hate to throw it out.
David Sleeveing is expensive but yes it can be sleeved. Store the block for a time when you can't get another block and find another block. If you insist on sleeveing it get ahold of Dana Mann (Don's son). He'll do it right the first time and will probably cut you a deal if your polite. Call me for his number if you want.
just take it to your local machine shop and have them take a look at it.they will be able to tell you what they can do and how much it would be.if its too much just look for another one.if you plan on doing a h.p.build then in my opp,i would like to start out with something alittle more solid.
x2 on having a machine shop take a look. A postage size picture on the internet is not the way to make a determination. Frank
I planned on swinging by there at lunch. I'll probably still pick up that other motor, I gotta think a bore and hone would be cheaper than sleeving, boring, crank grinding etc.
Around here a sleeve is only about $60 per hole depending on bore size. But there's probably more machining to do if you're going to go that far.
Sleeve it, it's only $60-80 more than the machine work your going to do anyway . Blocks can be had cheap if you have time to find one . I bought a few and found cracks on outside of blocks, 3 motors and 2 went in trash . so atleast you know what you are facing here . Rods are cheap, if you only need one I have a few stragglers
What are you planning to build out of it? Stock motor or slightly bumped HP for a street machine - yes. Big power for a boat or drag car - naw, get another block.
I've got a 425 Olds that had a score in one of the cylinders, but I just had it and all the other holes bored out to .030 over... It was cheaper to buy pistons and labor than it was to buy sleeves, labor, and a couple pistons... My engine jumped out of time and wacked a couple valves pretty good, then she got some water in her... Or you could just knock that hole out .060 over and run oversized rings....
