V6 vs V8

except that it had no camshaft. The valves were operated by electronic solenoids tied into the EFI system.

I still don't understand with all the advancements we've made, we are "still using cams." Of course there IS VVT

Even THAT is not "new." I can remember someone --aftermarket performance parts-- was making a centrifugal based cam drive in the ? 60s ? which never really went anywhere.
