So in a round about way you saying the heads will support almost as much motor as a P-51??? Please Clarify for me, I'm curious.

WTF Freelander???

Do not try to put words in my mouth or impugn my integrity because we have a personal beef!!! You are not curious nor do you need clarification. The HP that P-51's will support is well documented. 750 is not almost as much as 950 HP???

I said nothing about supporting X amount of motor. I simply stated that given the much improved exhaust port and intake flow rates as tested there is X amount of HP potential. I have dyno sheets of D0VE heads making 729 HP at 7200 rpm at 472 inches with not enough exhaust port. It has been well documented that fully worked iron passenger car heads will support 730 to 750 HP in a max effort application. Given the much improved exhaust port 20 to 30 additional HP seems reasonable and conservative to me.

I have refrained from talking about our personal feud online and the fact that i am suing you for breach of contract.
Why do you insist on baiting me like a gosh damned butthurt teenager? Why dont you behave like a man Mr. Freelander?

Do not try and rain on my parade.. YOU DIG???

If you don't want to answer the question posed thats fine, I understand, but to get so personal when questioned? You seem to have a real chip on your shoulder when someone questions you.

So in other words......Get your panties out of the Bunch Princess.......YOU DIG?

I don't know about your family but it seems alot like mine!

Scott, one more Question, if you don't mind....... What state are these new heads cast in? Or country?

Scotty,

Good job on the heads, those will be viable option for any that are thinking of spending money on upgrading on the older factory heads and want a little more potential. Costs seems reasonable to me for the fully ported version.

Some of you guys really need to price out the cost to redo a stock set of heads. Have you ever paid a mediocre shop to R&R heads before ? If you own the heads and have to do the guides, seats, valves and all the machining your looking at anywhere from $1100 - $1300 dollars. If you have to buy cores then add that on. Porting is $600-700. Add it up. Or buy that Ebay head for $650 then add another $1300, what does that give you ? For less flow and HP potential, you saved a $100-200.

I probably got 12-14 sets of D3 heads anybody want to buy them all for $100/set. You can then port them, R&R them, & sell them for $650/set and make some big money. Then I can get me some of these new iron heads.

You're losing it, Dfree. You need to get your head out of your ass and look around. You don't offer anything for the BBF, and yet you seem to think you can out-answer, out-wit, or somehow come out on top of the individuals who do offer items and services. You post up some ebay heads? That is your retort? You start talking about P51 heads? WTF???

Also, the cat is out of the bag for the individual that you are. People may take your money, but you're a piece of shit. You're trying to make other people look like shit, when the truth is you are the shit.

Snap out of it, and wake up.

And before you retort, I am trying to contribute to make you a better person. You can either listen and learn, or make yourself look even more stupid. You owe Scott an apology for the things you have posted in this thread, and to make things right with him. You are among men here, and you will be judged among them.

I think he was getting at the part were the exhaust ports flow almost as much as the P-51's.
Anyway very nice head

actually matt i think this has surprisingly little to do with cylinder heads. its a pissing match between two people who hate each other in the real world. there wouldnt be near as much negativity directed at these cylinder heads by a certain member if they had been brought to market by someone else.

Ah. good old high school pissing matches

why D3 copy ? I would think new iron SCJ copy is more in need . Jack R had new BBF heads with smooth ends . whats the chance they can produce a oem SCJ in iron ?

These castings were conceived by the designer to cope with the issues faced with D3 headed air compressors. Namely seat recession, cracking and exhaust manifold flange issues. The castings perform flawlessly in the application for which they were originally intended. There is a surplus now and I feel they have a place in the BBF performance market for:

Trucks
Motorhomes
Propane conversions.
Class restricted racers who must use an iron cylinder head.
Street terrors where the owners prefer for whatever reason to utilise iron rather than aluminum.

I have alluded to this in several posts. If i were to start with a clean sheet the large chamber passenger car cylinder head may not have been first choice. however based on the flow potential of the revised exhaust port and an already good intake port these castings when prepared properly will support some serious HP.

They were not ever nor am i saying that they are supposed to compete with CJ port castings. As is also stated earlier in the thread the majority of iron heads i sell are for the under or around 500 HP crowd. That is a pretty large market and i feel these castings fit...

Just my opinion but any class restricted racer is not going to buy a d3 style casting because if your in this type of class you will be fighting a losing battle with these castings.

Sounds like a fair question to me. Where are they cast? I would want to know before I put down my hard-earned American dollars.
