Mopar Engines ~ "Combinations That Should Have Been Made Available"

They also should've made ALL their small blocks run the '68~'71 Hi-perf exhaust manifolds!

Another thing is......why the heck didn't the factory ever consider running a 4-inch stroker crank on the small blocks, a la Chevy small block 400?? Seems like it would be bad *** and so cheap to do. Maybe didn't want to overload the cooling system.....?
