I have some spares sitting around that I am going to install this summer. I was wondering if anyone knows if the GP40p will work with my MAC unequal length shorty headers?

Does the driver side head have 3 bars on the front? If so yes, if not no.

95-early97 heads are GT40s

later 97 and up are GT40P heads

the intake is similar to the GT40 intake but is setup to make more lowend then your typical GT40. the lowers are the same

you can use BBK shorty unequal lenght headers on the P heads.

when i cared about my other stang i had this same topend on it

:yes:

I thought they needed some modifications to work?

nope!!! only flaw is you need MSD wires and need to put plug wires on first!!

why MSD? are the boots different than FMS?

with the MSD they offer true 90* boots and youll need like 3 of them for passenger side to clear and the fact that the other boots are adjustable as for bending

and i didnt use FMS just had the MSD
