the complete set up that i saw certainly appeared to be from a 4.6, what i need to find out though is what heads they ran ( 2 or 4 valve) and then what cam shafts.
one kit is brand new the other is from a test engine, they had explained that there were only around 300 built, but were not sure on the power specs, the new cobra engine i have is a 2002 build and rated at 260 kw, if the muzzy is only 300 hp, then this would seem a step backwards, even though i am not sure of the formula to convert kw to hp, i do realise that 300hp, blown or not still does not equate to 260kw. i did notice while there new harley blowers for the 5.4 and complete 5.4 lightning motors, can u get these to crack? or would they just be a show thing incapable of towing a loaded car trailer?
