Edelbrock aluminum head in the works

Time to get the pad and paper for the next custom intake!
I've heard that Edelbrock may have future plans for an intake to compliment the head.

Found this leaked pic on another forum:

For ~25 hp / ft-lbs that's expensive. At $1000 or under it seems less so. Hesco was charging 2,000 though.
This whole thread has me second guessing my 4.7 WJ, because a 4.7 stroker I6 w/ aluminum head sounds so-freaking-cool.

Generally agree with your comment regarding price. As parts of a stroker build I could justify because the potential multiplicity of numbers would justify.

For a vanilla refit/reman or 0331 replacement it is harder to make it make sense at $1300-$1500 IMO.
 
I think the important bits are how they arrived at their power numbers and what kind of cfm the head will support without major work. If it will flow enough to build 300 HP out of the box and all they did to make 25 HP was bolt it onto the block, that's one thing. Its another if it took the head, decking the block and a cold air kit.
 
The 55cc combustion chamber on this head will bump compression above a stock 4.0l by .28 point. Add the .044" gasket and its .42 point. The head could probably be milled a bit to bring the compression up even further, depending on what grade of gas you want to run.
 
Assuming this becomes available soon at a reasonable price I probably will toss it on as a replacement for the head on my LJ when I do its rebuild.
 
yup.

sucks that we just built what should be the last motor for 4643. i want that head, but not so much to ask Russ to go to round 4 with this thing..

I wouldn't think the small bump in compression would affect anyone's combination. The more efficient chamber should be good for more compression coupled with aluminum being such a good heat dissipater these engines will probably want a little more timing now.

Looks like they have a 3/4" deck too. Boost approved :thumbup:

It looks like it is missing two features that the Hesco head had. Enlarged pushrod holes so you can pull the lifters without removing the head and a raised valve cover rail so a spacer is not needed with roller rockers.
 
The pictures that I saw of it the other day, it sure looked like there was ample room for a lifter to squeeze through.
 
Nope. Just went back and looked, holes are too small.


They did miss a big one there.
 
What would the advantage be - cam changes without removing the head?
 
Well, I'd still put one on a 4.6 - then put that in a 2-door 2wd w/ 5 speed - and cackle like the villain in a "B" movie.
Y'know.
In the world where I have time / money for such things :)

Same here, but on the XJ I already have:firedevil


Kinda digging that Pentastar blower too........too bad that making work in my application would probably mean cutting holes in the hood...........or going Roadkill style and just leave it off...........as well as massive transaxle failures and non existant tire life:laugh:
