Ford Police Interceptor

I may have the opportunity to get ahold of some police interceptor exhaust manifolds for my recently rebuilt 460 in my Lincoln continental. Does anything know if this would be worth it over the stock manifolds? Any pics?

I have 2 sets of them for sale. I can take some pictures tonight.

Here is a web page with pictures of some scj manifolds. The scj and pi exhaust manifolds are the same shape, the pi manifolds are just a little smaller.

Here are some more pictures of the PI exhaust manifolds

Do you think that these would have noticeably better flow than the stock lincoln manifolds?
Yes, they are a huge upgrade. They are in a straight line and a lot bigger all around so they breath a lot better.
Sorry to butt-in on this thread but I was speaking to HPbyGD about using these same manifolds for my 60' Galaxie. He said he tried CJ's on his 63' Galaxie and the manifold hit the body mount. I was wondering in what places are the PI's smaller than the CJ's. Would you be willing to provide dementions of both these manifolds? It would be a great help. Once again sorry for Thread Pirate.
I recently picked up some manifolds and I am waiting to put them into my Lincoln. I might be able to measure them for you, I am not sure whether they will fit the Lincoln.
here are some pictures of the exhaust manifolds and the dimensions.

What are the casting numbers on those, are they the D2 or D0?

Take a look at this old thread their are some pictures of the pi and cj manifold. The ports are a little bigger on the cj manifolds than the pi manifolds.

Huge difference. They'll fit fine in a Lincoln. Heck, everything about a 460 fits better in a Lincoln; no 'skeet there's no room for a fan', no overheating etc. If you mod the evaporator case a bit you can move the engine back a foot without touching the firewall.

Check the old manifold over carefully for cracks, and consider some sort of stress relief in the connections to the exhaust. They're 40 years old and may crack - no big deal if you installed with good bolts and anti-sieze, but better if you don't have to deal with it. Relieve the outlets to 2.5" (P.I. were 2.25 when new).
If you are ambitious you could make a nice side business casting up new replacements using better iron, e.g. Ni-Resist.
Thanks for all this cool info from all you guys. Does anyone have experiance with the PI Manifolds with the 73 casting numbers. Is this different than the 72's? I dont hear about the 73-74 PI's too much on this sight. I think they came in 460 CI right?
