B head / C head confusion?

[ProjectRedMark]

If we can run the 01 Mustang intake manifold (a C head intake) on our cars with our B heads and IMRC's then why do we need C heads to run a supercharger like a kenne bell or the o.e 03/04 Cobra unit?

I'm only questioning this because I just searched car-part.com looking for a suitable intake to use when I install my C heads. When I looked up many of the C head applications and searched for the lower intake manifold (aka imrc plates right?) It crosses right back to the ones on our cars?

I've got to be missing something here?

It's bad info... you can use the adapters that came on the conti to put a b intake manifold on c heads... but not the other way around.

Ah I see. ( I think) So the interchange info is bad. Thanks that was kind of driving me nuts.

Buy a used conti engine. (for the heads and other parts) tranny holes are different so you can't use the block. Conti engines can be had for 2-4 hundred with 30-50k miles. Just have to look around for them.

I found a deal last year I'm still kicking myself in the ass for not buying. Some guy had found a 02 conti engine straight out of romeo still on the shipping pallet, no miles, brand new. Wanted $1100. I should have jumped on that deal. Its always good to search Craig's list in the Detroit metro area, never know who stole what from romeo and is trying to sell it.

Last month a guy had a new cobra jet engine on ebay, had the matching signed and numbered plate on another of his auctions. Said it was from Ford Mortorsports, never seen a signed and numbered engine available aftermarket.

Dad always said stealing engines from romeo was to easy.
Slap a new address on the crate, and thats where it gets delivered, lol.

We had a local guy die about 6-7 years ago. When they went threw his barn they found 30 brand new hemi engine blocks from the 70's he had taken.

That is almost the way i went just for the cost reason. The heads i have are from an 04 Aviator. I wanted to be able to upgrade to a factory blower easily as soon as i am ready. That is kindo of why I was not wnating to spend much on an intake for it because hopefully it will only be temporary. Looks like im going to go with the Aviator intake and Cobra motor mounts which MAY lower the engine enough so I can close the hood lol.

You will NEVER get the Aviator intake on that thing. Now if you can, it will be one of the BEST setups you can do. That intake is prized and sell for upwards of $300 or more easily. But its a big beast, no way to close the hood even if you shim the k-member 5 inches!

Better off getting a cobra intake on the cheap and them just selling it for what you bought it for. Or look for a Mach intake, sometimes they are overlooked and its the same thing. I have an 04 Aviator block/heads with Mach intake in my Mark. Tight fit.

Thanks for the heads up. Its always good to hear from someone who has done it already. Did you have any problems with the block? I thought about using the whole motor but I was concerned about the details ( accessory mounting, oil filter adapter compatibility) I am worried about the Aviator manifold. I see it is a beast. And the EGR is mounted on top and makes it even taller. I have seen mounts that will drop the engine about 2 1/2 or so inches and I figured I would need a cowl hood anyway for when the blower goes on.

How do you like the Aviator engine? Did you notice a big difference? Also you have a Gen 2 don't you? That bubble hood may make the difference. My Gen 1 may need the cowl hood even with your setup.

+1

99 or 01 Cobra, Mach 1, Marauder will all work. I would look for the Mach, rauder intake as 03+ heads ports are a little different.

Sure, Marauder will work - but then you have to move the battery and a ton of other stuff. Its intake is on the driver's side (odd huh?).

As for the aviator engine as a whole. I bent a rod with my original engine, so swapping the whole thing made the only sense. I also have ALL the Aviator accessories (except AC compressor) hooked up. I re-used the Aviator steering pump (lost variable steering though) and even the PS pump reservoir. I even used the Aviator alt - its the same pretty much anyway. Best part is that oil changes are a cinch now that the filter is located was forward. So my belt setup is stock for Aviator.

I think it would be the ideal thing to do. Build your Aviator engine up outside the bay. Paint, clean, etc. But the block is good. Sure, its not a Teskid block but it can take plenty of power. You will need some Cobra or Mach manifolds. I had spare Mach manifolds but lost them. But you can get a set for $50. You will have to mod the steering shaft to get past the manifolds. Just need some flaming river stuff.

The intake though, I would still be surprised if it even fits in a Gen II. I would have LOVED to use that intake. It has built in IMRCs giving the car great low and high end performance, something you looses without them. If you go Mach/Cobra you will probably have to remove the hood liner and notch the hood's lower layer. I can get pics of what I did. A Dremel made quick work of it. I did not have to shim the k-member like so many insisted I do.

As for the engine harness. A Gen II harness is a good match (should be near 100% spot on) but for a Gen 1 you have to modify one from ground up like I did. Was NOT hard at all. You MUST solder all connections. A lot of the stuff is resistance based. Converting to COP from wires is a great way to clean it all up and I have a chart (I think) of how to do that. Pretty straight forward.
