That was what I read once in an FE book, and sounds reasonable to me. Ohters here seem not to be so worried about it. However, the fact is to make room for a sleeve, the cylinders walls get thin. How thin is acceptable? The sleeve doesn't add structural integrity to the block, even with locktight, so you have to weigh things, like.....how much HP are you going to build it for?...and again, what's an acceptable limit. Fact is, if I already owned a 427 cross bolted block, or a thick walled 428 block that needed sleeving, I would do it and hope fro the best. But I wouldn't buy a block knowing it had to be sleeved, or already was sleeved. An article by Rick Voeglin entitled "All in the "FE" Family" mentioned an 8-sleeved block...done so for "greater cylinder wall strength". Sort of blows a hole in what I've ben talking about with sleeving. In a nutshell, there are so many unknown variables with sleeving, that is is hard to know if everything will be OK until the engine proves itself over time. The one thing that is known is that it is not cheap. Therefore, as you are looking for a block, try to find one that doesn't require this. A little bit more money, but hopefully some piece of mind. |
