The pushrod engines have a very limited RPM range due the extra mass of the pushrod putting stress on the valve spring. But i think theyve overcome that when I look at the corvette and GTO spoting these 6500 and up redlines.

But OHC engines have a more likely chance of snapping the timing chain and when that happenes in those engines its more violent..the pistons start striking the valves and you gotta huge mess.
