Mach1 engine
 

Does anyone have details about the 2003 Mach 1 engine? None of the articles that I have seen say if it is the 1999-2001 Cobra aluminum block or if it is the iron block from the GT. I know that it has new heads and cams from the 5.4. Any info would be welcome.

It utilizes the alluminum block and you are right about the cams and intake from truck/5.4 engines. It also has the ram-air shaker scood which will add a few ponies. It is supposed to make 300+hp but final numbers haven't been set. It should be one sweet car! Team Mustang already got it to run a 12.93@106 w/ just drag radials!!!!
