A New Cylinder Head for the SC.

The HEMI head design!

[QUOTE=427Cammer;849466]

Is it possible to sit the motor down further into the chassis (modify the K-frame and/or motor mounts?), thereby providing an additional inch or three overhead, and allowing a non-factory head/intake to clear the factory hood-line? What about transmission bell housing and oil pan-to-road clearance issues? Dry-sump oil pan that does not have a low-hanging sump bulge/hump?

I had "AJE" build me a "K" member that dropped the engine down 1 1/2 " on one of my cars. THey said that this was the max that could be dropped. Keep in mind that when you drop the cross member you are also dropping the steering rack. This is where the trouble comes into play. You have to run a set of "bumb stops" in your steering linkage to offset the drop in the rack. The max you can run is 1 1/2 " and still have a car that will steer correct. Just some more food to think on with this idea. Also keep in mind that the Cobra "R" hood gives you about 2 1/2 to 3" of room. Now if you know a GOOD body guy he can add some more to it and still keep it looking like a stocker "R" hood. This can be done by adding to the outside lift on the hood. These hoods have that first lift, then give the big lift in the middle of the hood. You could step up that first raise by 1/2 inch and sloop the second flat to give you another 1/2" or so. This would give you over 4" of lift, but still look normal. The "DOT" says in most states that you can only go up 3" but if you do it right it will pass inspection as the big lift will be the one they check. Now if the hood is already raised before big lift they won't even look at it, as long as you don't get too crazy.....Rich

Errrrrrrrrrccchhhhh...Back the truck up...Is that "start to assy" or customer cost? If it is customer cost, I am OUT. I can buy a car as fast as I can make this one if I am going to have to spend an additional 20K just for the heads/intake. Now, if it was a COMPLETE upper setup for about 10k, I can see me stepping up for that.

I love these car and it sad to see that ppl can't put $50 in for something that will help us all we spend more money then that on nothing we just need to get ppl interested . and as for the intake it does not have to be that thick maybe half a inch more will do

What makes you think that $50 will be enough for people to put in to make this happen?

You're silly, Chris.

That's the cost for the pattern work, tooling, casting, and machining. Customer cost wouldn't come anywhere close to manufacturing costs.

I personally wouldnt buy a head intake package that wouldnt allow me to bolt on a stock m90, mpx or whatever

Head wise I wouldnt buy anything that wouldnt allow a stock intake/ SC setup to bolt on...Thats just how I roll. I liek my lil v6..But not that much

Its like me buying yates heads for my SBF..Not happening.

I could see however a raised exhaust port as anyone buying aftermarket heads should have some sort of a full exhaust upgrade

[CMac89]

Those details will be worked out. We can build an M90 intake manifold, since retrofitting an AR to it is doable. Whatever material needs removed or added to a stock intake can be massaged pretty easily into/out of the pattern work.

The intake is the last of the worries right now, since it's application specific. The heads are first priority.

Long shot, likely -- curious what the details pro/con are with this swap.

Im extremely familiar with both the 3.0L and 3.2L SHO engines. Along with the later 3.4L V8 SHO engine. None of this is even close to possible or worth being discussed in this thread my friend....Two completely different animals...DOHC vs. OHV.

I've got a data file of a 3.8 split port head.
A friend of mine did a cat scan of my casting using layers .5mm thick.
It is currently an 500 MB "stl" file which is a stereolith file but I can get it translated into IGES or CATIA or UNIGRAPHIX or whatever quite easily which would be a 3d surfaced model.

I will be working on modifying the ports, water passages, deck thicknessses, etc. in the model to make it into the aftermarket SC head that everyone is dreaming of.

It's a step in the right direction eh?

maybe that can get the heads started

The one I'm dreaming of would be Direct Injected. I know dreaming.

[XxSlowpokexX]

Actually.

May be worth talking to Dan if he has done that type of work upfront.

If you could do a splitport head with an m90 pancake type intake allowing the use of lets say AR and m90 setups currently out there..That would be GREAT FOR US.

I still think a nice aftermarket single port head that can use a factory type intake would potentionally cater to many more people thus reducing overall costs in the end

That would be nice
