Actually you are. All variations of the 4.6 are under powered slugs. It wasnt until ford pulled their head out of their ass and put a supercharger on it that the 4.6 was even worth a shit. The only reason this mach one was purely out of a weight advantage. 305HP out of a dohc 32v motor is nothing to write home about. In fact its pathetic. The 5.0 is proof that ford sat on their ass since1993 and did nothing ground breaking with the 4.6 from an engineering standpoint. Thr hemi and the ls motors are the only reason ford built the 5.0. It's called competition and ford couldnt compete.
And when Svt was making the 03/04 cobra they tried to keep it naturally aspirated. Only after exhausting all avenues to get the numbers they wanted with no avail did they decide on going with a supercharger .
