There is no free lunch. For a low RPM street/strip combo the added CID is a big plus. The small head CSA(not including exotics) keeps the RPMs and HP down. Last year we had a cylinder wall fail in a mild mid 10 second street/strip car(J heads). That went 2 years with the 4" crank,it went 25years and 9yrs on the track with the stock stroke. Not very scientific test,but I disasembled a 408" street/strip shortblock today and the pistons look like they have 100,000 miles although it's closer to 10,000 miles.
