I don’t have to explain anything to you. I don’t care. You are a monotonous troll, trying to prove some silly philosophy that we should start with outdated, used up castings to prove we know something. There is no reason to do what you claim you do, unless you love mental masturbation and working to do work.
Chrysler didn’t improve heads like the W2 and on because the 302 is an *** kicker casting. Your premise is stupid. And faulty.
