Probably one of the best ( power vs life expectancy) in the big inch Hemi world is the 572ci - 4.5 bore X 4.5 stroke. The alky classes have used 4.5 stroke for years as well. If those are any indicators for you . I have a 528 nach asp motor now that needs attention and an trying to convince my self NOT to make it a 572. Also have a 525ci Blown motor with a 4.5 crank so I guess I feel they're safe,
