The E-460 heads are an option, except for the having to adapt an intake, and the odd headbolt pattern, and the rocker location changes on different heads.
Somebody had a set E heads on Racing Junk that had standard headbolt pattern conversion done to them, but don't know much about them, otherwise.

Talked to Vance the other day he hasn't done anything with the b-441 heads but said he has a set showing up really soon he's suppose to keep me updated on how they work out for him.. it just sucks cause Thor heads are near impossible to get the idt 1600 series head is hard to get other than that the next best bet I believe is the e- head... somebody needs to build a head for a big " ford that isn't hard to get a hold of..lol

Here is a picture of the hemi heads on our motor. It is an 815 and is in a 10" tire stock suspension Mustang.

I think you could fit a regular intake under that sheet metal one. Basketball 

Looks like an external wet sump?

It is an external wet sump. I wished we would have went with a dry sump but at the time we were pretty much out of room in the engine compartment.

Eric, if that is what you wish to do, it would be best to get with Jon Kasse. He has the most knowlege on these, bar none. Not a cheap deal to build, operate, and maintain.

I agree Schmitty. I'm going to get a lot of the stuff from carol carter.. I'm going to build my own deck plates on my mill. Not sure if I want to put o-ring grooves around water holes in the spacer then have it sleeved or how I'm going to do it yeaht?

The reason I ask about the cd is I might of got a set of rods if I do 12" deck my math says I would have a 1.625 cd with 11.7 would be 1.325 and 11.625 1.250 with a 7.625 length rod 5.500 stroke. I can will be able to deck the block to what ever I want with that said their is no reason to buy a 2" thick peice of material for deck spacers if I don't have to??

The last time I had a friendly chat with Mr. Kasse, he explained that anything that moved in those large ci engines were disposable items with short life spans.

I'm not sayin I don't agree with u they might be but if the piston speed is kept to a norm does the motor know how many cubic inch it is? I was always told piston speed is the hardest thing on motor?? Like I said I'm new to this also..

7000 rpm with 4.5" arm to keep piston speed the same is under 6000 rpm for 5.5" arm. The big hemi heads aren't going to work down that low.

At 7500 rpm with 4.5 stroke the piston speed is 93.750fps with 5.5 its 114.5fps did I do that right?

Eric, you need to remember that the 815 CID engine that Joe Mayabb posted pictures of is with the 5.000" bore spacing. The B-441 hemi heads from Carroll Carter are also referred to as the R D hemi heads (Roberts Design) and are available in both 4.900" bore spacing and 5.000" bore spacing. Personally I would just get the tall deck alum. block from Carroll that is designed for those heads, because you are going through a lot of trouble trying to make one out of an Eliminator block. One question that comes to mind is;, are you going to hit water with the Eliminator block when you notch that block for pushrod clearance for the Hemi exhaust valves?

Good points charlie?? The class I run does not allow aluminum blocks.. I know how retarded is that. That's the whole problem I'm having? Now the chebby guys get a 11.7 I think iron block they can run but we are still stuck with the 10.300 its bullshit if u ask me. I've complained about it for years u know what they tell me just build a chebby well screw that...lol I'll do some more research on the pushrod location. Thanks

With those piston speeds, the 5.5 is almost 25% more speed. There is also crank flex to take into account with the minimal journal overlap too.

Oh yeah, lots of 640 RD hemis out there with cast iron blocks. 650 fits alittle better in a 11.2 block.
You just need to get the powers that be, to make up some cast iron 11.2 blocks.

They will with the proper valve and port sizing.

This guy had BES build him a 660" Hemi for a 2014 Cobra Jet Mustang. I don't know what the block is but you might try contacting him. Very nice motor and car.
