All new parts, you're looking at over 1100
Used, of course you'll spend less but I hardly see any used Bullitt intakes nowadays.

Why? PI manifolds "dont fit NPI heads" either and look how many people do it. The PI heads don't flow THAT much better than NPI heads anyways.
you are correct, invertmast used to have a SVO blower for a non-pi motor but it was on a 04 GT motor. it DID fit but it took enough RTV to kill a horse for it to "fit"
if you want to rig it up like that, then be my guest and have a ghetto-ass setup that WILL end up with vacuum leaks. but in order to do it correct you need PI heads. plus with the PI heads you get the increased compression and a wider choice of cams.

I have a feeling if it's cast to fit PI heads it'd fit exactly the same as a PI manifold fits on NPI heads. Use a PI gasket and seal the coolant port w/ RTV and you'd be fine, use a NPI gasket and seal the edges around the air inlets and you'd be fine. I don't see how it'd be very different from a PI manifold on NPI heads (which many have done, including myself). Plus that increase in compression reduces your boost capabilities if you ever want to go the FI route. The wider cam choice is a plus, but thats nothing major I guess to some people.

When I first "test fit" the intake to the heads to see if everything lined up, I had no gaskets(I just set the manifold on) and it didn't line up. It fits in so tight, it was touching the edge of the machined lip of the heads. Once I threw the gaskets on, they spaced it up high enough so they didn't touch and everything lined up, but it's tight.
I dont want this to get into a PI vs NPI head debate since we have seen plenty of those, but I will say flow isnt even half the reason the PI heads make more power.
and before people get into th intake swap end of it, ask yourself why a NPI headed car with the PI intake swap on ET Streets with cams and intake mods would still only be within a .1 of ET with a PI vert with only gears and exhaust for mods?
If the heads were not that big of a difference then shouldnt the cams on the NPI car and the fact that my vert weighs a few hundred pounds more (not to even count the fact I was on nitto's vs his ET streets) give him a decided advantage?
my best pass with 4.10's and welod in flow masters on nitto's wqas 13.66 99mph.
Rick (COramprat here) has a PI intake, Comp 262's, 4.10's, prochamber and a TB/plenum on ET streets, his best pass to date at the same track is 13.8 at 103.
yes his mph is a godo bit better, but that is accounted for in 60'. his was a 1.9* vs my 1.8
all in all the car with cams and more mods in general should have killed me all around but yet his ET is 2 tenths slower.
I think PI heads are well worth the swap.
