When your saying Make Power your talking 8,000+ rpm's ?

Yes. It’s funny this comes up. Chad Spierer has a post on his Facebook page about a cylinder head he did and it was a “low rpm” deal.

In his world and in most of the performance world, 8500 rpm is a low speed engine.

Unless you are a Chrysler guy. Than anything over 7k is uber high rpm and beyond the scope of even a strip/street car.

RPM is horsepower. It seems to me that in general Chrysler guys fear rpm way more than they should.

I get TBO and I understand it, but it’s not 1980 any more. And before I digress I’ll just stop typing.
