Why do I keep breaking rocker arms?

I dunno.. i just dig em more... the ford big 6 (300 or 302?) is a badass 6... the chevies are kinda meh...
Yeah but we can find many more examples of inline engines of all makes going on for decades with a piece of leather belt for a rod bearing, burning oil ...w/ different size piston from a field repair at some point. 1950's ford tractors are a great one.
