A good thing to remember when modifying engines for performance is that few questions such as those have a definitive answer. When I built custom rifles I was often asked "how far can I push speed before I get in trouble?" and my answer was always the same. Add powder one tenth of a grain at the time until it blows and then back off a couple.
The smart knew what I was saying, the dumb would ask how the heck can that work???
Same thing applies to building a hi-perf engine, if you run into an "expert" who claims different be careful about what you take as gospel from him. Marty (WI50) has always been good about pointing out power vs longevity and I am sure he willc hime in with an answer you can take to the bank.
Some here boast about how big they build and might say "X" sleeve thickness is it,,,yet at the same time they sit on the sidelines among piles of busted up parts. The big gun mentioned earlier that won a class at Tunica is currently not running. How thin were his sleeves/ maybe the so-called expert will clue us in but what I know about the Allis block I would have to say DAMN thin. It was obviously hard blocked BUT hard block has it limitations too. Did his oil ring collapse or did his tin foil sleeves fail? I have my guess but that is all it is based upon experience with other engines that had very thin sleeves and hard blocked to back them up. Fact is you cant run tin foil for sleeve material and depend on hard block to save your dreams from destruction on past the test stand. If you are doing nothing but pulling then hard block has many pluses but also carries some baggage that cannot be ignored, Marty also has made mention of that.
