That article says "cost almost as much as a used cherokee". LOL, almost twice as much as a used Cherokee is more like it.

On the new head idea, I dont see it really panning out. Unless youre going to offer a head with HESCO performance that is in the $400-$500 range, its likely just not going to sell well enough. The majority of Jeepers just arent doing significant engine upgrades to the 4.0L. I can say personally that if its $1,000, I would prefer to swap in a $400 8 cyl engine and $300 trans and make a boat load more HP and TQ than a 4.0L with a new head,

You'd have to be pretty damn picky to find an 8 cylinder for 400 that puts out a "boat load" more than these 4.0's bro

There are probably quite a few of us out here that would like to see an affordable alum head to compete with the hesco head. But like said earlier the price would have to be a big amount to make it worth while. Some of us are not engineers to give some of the imput you are looking for other than better power, mpg, air flow. If the price is anything 1k or more you can get a crate motor for starting at 1400 bucks. JUst my 2 cents on it. I would love the gains but cant justify the cost.

I have a 1965 283 that makes 300 Ft Lbs stock, I can get a pre-smog 350 for $400 which will make more HP and TQ than that. You may be forgetting that between 2000 and 1976, engines were in general no good. If you take a late 60s early 70s 350 and throw it in there you will be starting a good bit ahead. Add a couple hundred bucks in digital fuel injection and your winning big. Only thing better than that is to buy a legitimate v8 like an LS1 or preferrably LS9. I personally wouldnt waste my hard earned $$$ on a V8 made after 1972 and before the LS1, they make less power than a new v6 camry

Edelbrock is the company talking about doing this project.

I know what you are saying but you would also have to consider the cost of engine and trans mounting, drive shaft mods, radiator (modify existing or new custom built) new exhaust system, electronics, just to name a few things. Not to mention the time envolved, it all adds up quick!

Don't get me wrong, I'm not trying to sell anyone on the idea just trying to see if there is any real interest and get some feed back like this. Hell, I would probably do a V8 conversion too before spending $2,000.00 on a Hesco head for the 4.0L. Though I don't really think $400.00 is going to buy much of an engine (as-is, that doesn't need anything) to start with.

Thanks for all of the comments and input guys!!!!

I'd buy an edelbrock aluminum head for 500$ Im installing my stroker that will (fingers crossed) net 60+ HP. You bet I would have bought that head a week ago while it was at the machine shop. People will buy them, they have to be available first. (2000$ = unavailable.)

plus i know 5 people who have jeeps weather it be a TJ, XJ, or ZJ, they all have 4.0 and we all want more power out of them, an aluminum head that didnt cost $2000 and made by edelbrock would be awesome!! as far as power numbers, if it would make 30-35HP, all the ports were polished, and came with at least valves and springs with intake valve increase to 2.02" over stock 1.94" and increase exhaust to 1.6" over 1.5" stock valves. i would guarantee that i would buy it

Better flow. Bigger valves. Double valve springs. Cost less than $600. That's what I'm sure every one would like too see. I know I would.

well, in my opinion if it was a direct replacement 4 liter head there's no way it would be over 750 just because it's aluminum. and if they made one that was tuned up maybe 1k to 1200. 2000 bucks would never sell.

sounds about right, come up with a good head for 7 or 800 bucks I bet it sells like hot cakes.

the problem of why they are all expensive guys, is because they have to create a whole new mold and create a new program to machine it all. plus the cost of aluminum aint cheap. so if they do come out with it it will be more than $900 because they still have to make money on these things. so i can almost guarantee that it wont be anywhere close to $600
