Big difference between those "pushrods" and these "pushrods".

These are not "old" engines. They are new engines with an "old" design, that turns out is not so old.

So you change springs every 20,000 miles... small price to pay for the performance and package you get.

And do not forget, ALL the uber exotics with these performance (and less) figures ALL require HUGE maintenance efforts at major milestone intervals..
