Doing some reading from Richard Holdener, and I came across this, it is worded as follows: "The 3v motor was equipped with JBA long tube headers feeding 2.5inch open pipes. The F.A.S.T. system was used to dail in the A/F ratio at 13.0:1, and the timing curves at 30 degrees total advance. Running in this configuration, the stock 4.6l 3valve produced 356hp at 5800rpm and 392ft-lbs at 4300rmp."
Is this possible? is it safe for the motor? Thanks all.
I am guessing it's crank HP, in which case there is nothing at all weird about this at all. The FAST is just a tuner, no different than the Predator or SCT-2.
