Name one pushrod engine modified or not that can rev higher than 9k one thats all I need.
Nascar motors and high end drag motors can spin well over 9k some even past 10K
have you looked at the physical dimensions of a 4.6L cobra motor dohc , and a 5.7L LS1 ? the pushrods allow the cylinder heads to be MUCH, MUCH smaller. a phsyiscally smaller engine that can sit very low and very far back and be easier to work on.
actually a 2-valve 4.6 whose heads are smaller than a 4-valve motor is physically bigger than big block Ford motor
