[DeTomaso] To sleeve or not to sleeve

[Charles Engles]

Dear Dan,

             Hmmm.  Yes, the experts can be wrong.

             However, regarding the shop in business for forty years that says they can sleeve all eight and it will be fine, stop for a minute and ask yourself: "If that is true, then why do people fret trying to find a good solid Cleveland block?   Why do people go to the effort to get them sonic checked for wall thickness?   WHY do they do that, IF the simple answer is to take any old 351C and simply sleeve all eight cylinders????      Possibly, just possibly, because while it can be done,  the durability and longevity are dubious and poor??

                  Warmest regards, Chuck Engles

Yeah, I was hoping someone had been down this path before.
After so many screw-ups at supposedly top notch engine shops I don't know who to trust in that industry either.
The shop which has the engine now has been in business 40 years and says they can sleeve all eight and it will be fine. But I'm not "sold".
Probably on SBC or GM big block but Cleveland's have such thin walls.

Dear Dan,

                  The answers to the question are: 1) seek out a reputable and reliable machinist and engine builder with actual Cleveland experience and follow his recommendations; or 2) seek out amateur, non-machinist, hear-say opinions and sort out the truth from the (dis?) information.

Then the question becomes:Is it better to have a .030 block with one or two non adjacent sleeves or a fully sleeved block at original bore?I've been told you get heat transfer between cylinders on a Cleveland at or over .030.And we all know there's already too much heat in a Pantera engine.
