To honestly see what works, and doesn’t work, follow the boat engines. Hyd rollers are used extensively in marine applications, and if you want to break something, that’s where it will happen, in a boat. Only circle track dirt racing breaks more parts....lol. The boat guys have narrowed it down to only a couple brands that will survive. Mopars are even worse than a BBC, because of lifter weight.
