I have had 2 (two) race blocks sleeved (1 rockblocked, 1 not) No problem w/either block. Id say it depends on who is doing the work. As long as you can find a competent shop...go for it! (esp w/a numbers matching block) Good Luck! [img]/infopop/emoticons/icon_biggrin.gif[/img]

I had the same problem on my original 64 tri-power block. I had no choice but to sleeve it. After that experience I would not be at all reluctant to use another sleeve.

Definately depends on who is doing the work.
I had a sleeve put in a 455 over 4 years ago, followed by filling the block to within 1/2" of the water pump holes. Never had an overheating problem, or an oiling problem, and that engine is still running today in someone elses car. It went through 1.5 years of daily driving to work and 3 seasons of drag racing (making between 50-75 passes per season). And the kicker is the shortblock was assembled by an old man whom a certain engine builder in my area considers to be a "junk builder" (yet I've seen several of said engine builders motors blow up). If it is done right, it'll last. Depending on how much material they need to remove to insert the sleeve, however, you may have to fill the block to support that cylinder wall.

Sleeveing a block is completely acceptable, assuming a competent machine shop does it.
In fact some racers prefer sleeves over standard bores! They will actually have a perfectly good block sleeved on all cylinders to promote a more uniform wall thickness & promote a greater degree of reliability. It is my understanding that the sleeveing can be done by press (interference) fit alone or along w/ welding.  SECOND AMENDMENT: AMERICA'S ORIGINAL HOMELAND SECURITY. I Misus Rash'!

I've got a sleeve as well. Car runs fine. Just make sure you clean out all the "slag" and shavings that might be left behind in your block.
