Not Ranked
Nope, but nobody has been very sucessfull in making a coversion for variable valve timing retrofit for any pushrod V-8's and many people have been trying for decades. That product doesn't even change the duration, just the lift; so in all fairness it is not a variable valve timing device as they try to claim it is. Well a tiny bit of added duration as measured at 0.050" valve lift as the rocker ratio increases, but not much.
Their "dyno numbers" just prove that a higher valve lift will make more power, so why get an overcomplicated system that costs $1000 so you can lower the rocker ratio at lower RPM's? The only advantages it showed on their dyno page were miniscule and all under 3000 RPM, and they should have wringed out more RPM with the cam they picked, HP was still increasing at the 5500 rpm cutoff on their chart. Spend the money on a good cylinder head porting and quality roller rockers, you'll go faster.
