Big Chief heads for big block Buick

SF600 stands for superflow 600.... It's a flow bench... Like CFD isn't a person it's computational fluid dynamics... Keep googling, you'll get it

 

Excellent, we will be very interested in the pictures of the heads, and of the engine with them on it. And then of course the performance.

All of these are your keys to sales in the future.

I'm on the edge of my seat in suspense waiting to hear that long list of qualifications that makes you the resident airflow expert....

 

you said it all Jordan. an tht was all it took. c you soon about some port work on some more heads from me and maybe a bigg mtr 4 you to do. call you on SAturday

Geez, Chris/Jordon, you both sound young now. How about just going back to work and really getting something done, both of you, because I know you both have work to do. Now go do what you guys do best. Build Hot Rod parts. Both of you seem to have experience that can be shared with others.
Jordon,
What bore spacing is the cylinder head casting normally machined to that your picking to use?

 

Jordan Not trying to throw stones just asking a question.

Why would you choose a casting that was cast for a bore spacing of 4.840 BBC when

The 440 Chrysler and Hemi have a 4.800 bore spacing and the Buick is 4.750? The closer you get the fewer issues you will have I would think?

Indy Cylinder Head has a Predator head for the Chrysler, it flows very close to the big chief. Has IEIE layout, rocker system is already designed and available off the shelf, Intakes are available for it off the shelf, bolt pattern is very close to the Buick ( so bolt holes will be in very close proximity to what the casting was designed for )

I have spoken to Carl the owner about this and he is open to selling castings for such a project. I have just decided to put it on hold, and wait and see if Mike T. is going to come out with a new head for this block.

 

Because they dont sell a raw version of the head. Dart doesnt even sell an unmachined big chief head I happen to have a connection. Both heads will have to have a Buick bolt pattern put in them, both would have valve locations changed and they do have a shelf manifold but it again would have to be modified. Doesnt really matter what casting you start with its going to be the same amount of work to get it to fit, work, and be machined to work on a Buick so why no choose the biggest and best? You also have to be able to get the castings should anyone or more people want them.

 

sorry I missed the part where you said you were able to talk the owner to get you a set of castings. how much was he talking just for the raw heads? whos going to do the bolt patter, valve angles, and other modifications to get it to work? I know lots of guys think "oh I just change my CNC program" it doesnt work that way. Theres a million problems and things you dont see on a computer screen than you do when the head is right in front of you. I have worked on modified heads before and I enjoy it was trying to help the Buick guys out but if all anyone wants to do is try a pick fights, talk ish, and wait around and hope someone else might get something done well then by all means. like i said I can get castings now and start working on heads NOW. The window is rapidly closing.

 

Last year when I was looking at making billet heads I to came across the Predator head and thought it was a natural choice to adapt in place of a buick head because of the bore spacing etc.

 

Jordan

Call Indy and ask for Carl he is hard to work with, and get a hold of. However if you can get along with him It might give you another option? he will sell raw casting (at least he would to me).

Good Luck I will be a potential customer when you are done.

 

what does it matter if its "close" if it still needs to be moved? wouldnt it be smart to just start with the biggest and best you can find if its the same work to be done? Ive seen DRCE heads intended for a 4.84 modified for a big block ford 4.9 and 5.0 bore spacing blocks. Ive seen the Indy head and it is a good head but do whatever you like. I came on here only to buy and sell buick parts and get stuff for my lesabercat till I was urged to do something for the Buick guys for cylinder heads. My info is posted and Im tired of typing. Call or text if your a serious racer Im going back to the for sale sections

thanks

 

Sorry Jordan I type slow so a couple of responses before I got this.

I am not looking for a fight, If you look I hardly ever post on here. If you can pull this off it will be good for all of us, and save me a lot of money in the process.

As for your question we did look at as many issues as we could see up front, ( and god knows you find more when you start modifying).

This was or is going to be a one off set of heads for me only, if TA does not come out with a better option first. I am not looking to sell anything. If you can do a small run and make a buck in the process, cool I will purchase from you.

My head guy is a long time Chrysler head porter and has built many a set of the Predator heads. All of the work is going to be old school one off, no CNCing ( Nothing is out there to copy ).

Good Luck and keep me updated.

Nothing against you, but I was one of the Bulldog block donors that never got a block. So From here out I either do it myself or wait until I can walk away with the product.

 

I know lots of guys were screwed by the bulldog guy but I'm not taking deposits so I can start making a mold I can get castings now to be machined that's the difference. I talked to the guy who casts heads for TA and he says it's going to be almost 100k just to get started to do heads. I don't know if it makes fiscal sense to do that with what few guys would buy them but it tom pulls the trigger then by all means that's the best route. If there's anything I can do to ease everyone's nerves over putting up cash for castings please let me know if you want to wait another year till they do another run or whenever mike gets his heads going then you are a more patient man than I.

 

Folks,
TA Performance is in the works of building a new race head to set the record straight, this job is under contract. It is a Twisted Wedge design as we are calling it at this time. Cad drawings are mostly finished, but it is in line to the 350 SP1X single plane intake. This intake will be first to arrive, tooling nearing completion. The 350 cylinder head cad design is very close to being finished and flow testing of port designs are very near. The 455 race head is the last in line for completion as my wife feels this will show no profit so why do it. Well, i guess it's a bucket list thing for me. I feel it will work out, plus we all get to have more fun. Hopefully the Buick community will back me and help make these projects pay for them self's.

 

thats awesome mike! its good news the 350 guys are going to be getting some good quality speed parts. Is there an ETA on the 350 head? I have a guy wanting an iron race head ported and if its close I might just have him hold off. How far out is the big block head? I know this stuff takes time and it took awhile just to get the block done and going hopefully soon we can have big heads to go with it I am not looking to be a cylinder head manufacturer or compete with TA in anyway just trying to offer the option of a big race head for guys who want one now.

is it possible to post those CAD drawings of the big block stuff when its done? Im sure lots of guys would love to see whats in the works I know I do! I understand if not though somethings got to be kept top secret lol

 

Hmmmm!!! ray:ray:
Cheers

 

:shock:

 

After all the BS is done I would guess no one in the Buick community would pay what the top pro stock guys pay for their heads. To get the best, you would have to buy at least 3 sets and have been buying for at least a couple years and you would pay over 6 figures to get them. I have personally talked to pro stock guys who flat out told me they will never be competitive in pro stock because they "can't buy" and can't afford the heads to be competitive! The right head for any specific combo is the most important part for your competitive race engine. You will need a good block that stays together at 10,000 rpm. Thanks "Mike T"

 

What "BS" do you speak of, Ken?

 

Hi Gary, I am talking about the insults. We already know what can be done to a solid Stage 2 head, and we know what can be done to the Big chief and still bolt on a Buick bolt pattern. We are talking over 600 cfm not 480-500. Like I stated before this is going to be a very expensive proposition. If it were cheap more than a hand full would buy them. The same thing could be done for a 350" Buick. One of my best friends recently retired from his own machine shop business. He now works a very short week programming for a friend. His main business was making high end race parts for Formula 1 and Indy cars. What that means is every one of those cars had his parts on them. I see him every week and have for 20+ years. We are exploring writing a program for the Big Chief and a solid billet head. Remember not a single person has put a dime down for the 447 heads and I doubt if Mikes new 455 head will sell more than 25 sets. A prostock style head will need new studs, valves, rockers, intake, headers, springs etc etc. How many sets does anyone think will be purchased in the next 5 years? Two, three?????? This kind of effort and expense take teams of racers supporting one car. I really don't car who knows what or does what. I only have one goal, and that is to see a VERY FAST BUICK and don't care much what it takes to get there. This process has been way to slow for my blood. ou:
