is their any difference between the Mach 1 and the 03-04 Cobra in the cam's duriation and lift? a buddy of mine said they was and he said the engines were the same with the exception of a shaker to a S/C ... i said its a night and day difference cuz of forged internals, iron block, pistons yadda yadda yadda u know the story but ya back to the main question

is their a difference between the Mach 1 and the 03-04 Cobra in the cams duriation and lift??

 

any one

 

The lift and duration specs are the same for both.

Camshaft lift: 392"/390"
Duration at 50: 232"/236"

 

thanks

 

ummmm wait i think the cams on the na cobras and the mach 1 are a little different. I read that book on 4.6 engines and it didn't give the specs but it did say the na cams were a little aggressive
