uh....well....I am going to have to go with a NO on that one...sorry!
I'm fond of the Cobra intake over the other GT40 and explorer. I just got done painting mine so it will be ready for when I get done with the H/C/I swap.
How much power could you make with gt40p heads ported, ported cobra intake, 70mm throttle body, 1.7 rockers, x303 cam? All this on a 306 with a 9.5:1 compression ration? This is for a friend with an 87 t-top gt.
