Thanks for the reply. As a Third Gen owner, I'm so glad to see this and other new products developed for our cars.

Toddoky, is there any headers you would recommend that bolt onto the block and the Blackheart system without, or require little, modification. I am extremely intrigued by the sound and look of the system, but I want to make the swap as easy as possible. Its going to be bolted onto a 355 Vortec, with a LT1 T56. I haven't purchased a new transmission mount yet, so I'm open to suggestions as well. Thank you.

toddoky

There aren't any that I am aware of personally. The system was designed as part of the Hooker LS swap system for 3rd-gens, so the inlet tubes were positioned for connection to the Hooker 3rd-gen LS swap long tube headers. I have performed a custom adaptation of the system to connect it to a set of Hooker 2210HKR SB headers and it does take cutting and welding to make it all come together. That same requirement would hold true with any set of SB headers you would be trying to connect it to.

89TransAmBoss

Thank you for the insight and the quick response. By chance, do you have pictures of the connections you fabricated for the 2210HKR headers? I'm not to worried about cutting and welding. I have some 2.5" pipes laying around that I can play with. I would love nothing more but to have true duals. Thank you for all the help.

toddoky

Yes, see post #133 of this thread: https://www.thirdgen.org/forums/ltx-...roduce-lt.html

hello iam putting hooker blackheart exhaust on my 1984 camaro its going to have a 700r4 trans. can it be put on with the orignal crosmember. Or is there a swap one

toddoky

The exhaust system inlet pipes were designed to run tightly tucked under the arches designed into the Hooker transmission crossmember, which is not compatible with the mount location of a 700R4 transmission. You'll have to cut/modify the inlet pipes, or make new ones to suit your application.

Stainless Works does. It is sold exclusively through Hawks Thirdgen and it is the baddest sounding exhaust you have ever heard on a thirdgen. It is on the 700 RWHP Storm Trooper car. And I have it on my car too. Here is a sound clip, and yes it really does sound like that at idle. My car has a higher pitch howl at WOT than the car in this video.

So I've been trying to put together an exhaust system, and I'm really interested in this blackheart setup. I know its overkill for a 305, but it would also be future-proof, plus it wouldn't be much more expensive than finding a Y-pipe and catback anyway.

My question is, will the blackheart 70501426-RHKR work with the hooker shorty headers, or would I have to get the long ones?

Also, 86Base, what magic did you use to get your car on those ramps facing opposite directions?!

toddoky

The Hooker Blackheart 3rd-gen dual exhaust systems will
only connect directly to the Hooker Blackheart 3rd-gen LS swap long-tube headers when they are installed with the Hooker LS swap transmission crossmember. If you want to use them with a different combination of parts, you'll have to do some adapting/fabricating.

I Jacked up the front and put the ramps under the front and did the same for the rear. that's the way I had the car on the ramps all winter with no drivetrain so it woudnt move

turboguard

Time to invest in another set of ramps! Jack stands scare the crap out of me

Lurbie

iTrader: (3)

Shouldn't that be the other way around? I have never seen a jack stand fail, I have had ramps fail, I have seen ramps cracked, busted, and regularly misused also.

86Base

I love my rhino ramps. I have used the a ton in the past year and re worth the money. $80 for 4

Lurbie

iTrader: (3)

That's a great price. Don't get me wrong, I have and use ramps, but only for short term stuff like an oil change. If I pull the floor jack out, the jack stands are going under too. Where did you find them at that price? My kid ran his car off the wrong side and put a huge crack in the plastic, so mine are trash now.

QwkTrip

iTrader: (22)

You just need stronger jack stands that inspire confidence. 4 ton jack stands are relatively cheap and you won't be nervous to go under.

Will my Alston subframe connectors pose a problem for installation of this exhaust system.

they're sort of an "inner" SFC as opposed to the more common "outer" SFCs.

I have the inner Alston and the outer UMI with the Blackheart system really no issues. The hanger for the passenger side pipe off the collector comes real close and maybe will require some modification.

Todd,
I'm interested in this hooker dual exhaust system for my 87 Formula. I've got the SS Works long tube headers with 2 1/2" collectors on my 383 SBC, stock 700r4 trans and cross member. From what I've read looks like there would need to be some fabrication to connect the head pipes to the headers. From dealing with the head pipes and Y-pipe on the SSW headers to my current exhaust getting by the stock trans cross member was a little tight to say the least. Would you know is the Hooker system designed to work with the stock cross member?


Thx,
Tom

toddoky

Hello Tom. The Hooker exhaust system will not clear the stock transmission crossmember, since it was designed specifically to take advantage of the high-tuck clearance arches designed into the Hooker 3rd gen transmission crossmember. You will have to modify the exhaust system inlet tubes to get them to route under your crossmember.

SuperRamFormula

iTrader: (1)

Will that Hooker 3rd gen trans cross member work with the original SBC 700r4 combination with the torque arm in original mounting location?


Thx,
Tom

toddoky

No it won't, the mount location on a 700R4 is about 4" further forward than the mount pick-up point on the center beam of the Hooker crossmember.

Jetmeck

iTrader: (3)

Nice tight fit on the exhaust but its impossible to not have rattles and bangs. There isnt enough clearance......

Linson

You speaking from experience?

BADNBLK

iTrader: (11)

Not impossible at all. The system fits perfectly and is mounted very solidly.

84z28_

what headers would work for this exhaust? what is there to modify?i have a 1984 z28 5.0 h.o. with a 700r4 transmission

toddoky

The system is designed to provide direct connection to the Hooker 3rd-gen LS swap headers and to clear the arches in the Hooker 3rd-gen LS swap transmission crossmember. Modification/fabrication work should therefore be expected for installation with any other set of headers and transmission crossmember.

Ozz1967

iTrader: (4)

With a 700R4, none. You can't get around the trans. Though..if you get Dyno Don headers, you can run a dual exhaust using the factory routing around the front of the oil pan and then hook the two invividual tubes to the dual exhaust.

Ozz1967

iTrader: (4)

I"m going to be using the Blackheart cross member in my LS swap with a 700R4 and the holley LS motor mounts. I have to swap tail shafts to the adapter that puts the 700R4 mount point in the same position as the TH400. This should allow me to mount it succesfully. This system will not work with a SBC...only the dual exhaust "Cat back" portion might work but will need to be modified with whatever exhaust headers you're running.

toddoky

Good work there Rocket-Doc. We’ve actually taken what you suggest a step further and developed a new set of Hooker Blackheart SB Chevy headers for use with the Hooker Blackheart 3rd-gen dual exhaust system. They will be getting released in the not to distant future.

skinny z

Well, THAT is interesting news.

toddoky

Yes it is skinny z. We've been doing the same thing with many of the vehicle applications that we've developed LS swap systems for over the last 7-8 years. Some applications have received development of new SB and BB headers that work with the Hooker Blackheart exhaust system(s) previously designed as part of the LS swap system for the vehicle in question. An example of this would be the 1st-gen F-body application.

Rocket-Doc

iTrader: (11)

Interesting news, a day late and a dollar short for me sadly. But great news for others. the kit is really well made. I was very impressed with it. Header flange bolts still suck, but what can you do...

toddoky

I hear you, that will always be the case with the development and release of new products unfortunately...someone is always going to end up getting the news at an inopportune time. Post up some picks of your install here so that others may benefit from your experience.

skinny z

To chase this development a little further, what crossmember will be required? Will that too be something new to come along that will be transmission dependant or perhaps you will adapt some existing LS swap crossmember to suit?
I've purchased your crossmember for the LS/TH400 application and will have to adapt it slightly to fit the Caprice style TH700 that I recently had built. (The rear transmission mount is part of the extension housing rather than the main case. This puts it at approximately the same dimension as the TH400.)

toddoky

The collectors of the new Hooker Blackheart 3rd-gen SB headers terminate in the same basic position as the Hooker Blackheart 3rd-gen LS swap headers, so the most efficient exhaust system routing will be through the tunnel area as we did with the LS swap exhaust system, The prototyping of the headers was carried out on car that was using an unmodified Hooker Blackheart transmission crossmember as an integral part of a T56 swap and I believe you should be able to take advantage of the crossmember you have purchased with a little effort (you may have to build a cantilevered mount adapter bracket). The TH400 mount is about 3/16” further back than the mount on a 4th-gen F-Body T56 and the mount on the earlier LT1 T56 is about 5/8” further forward than is is on the 4th-gen T56...I’m not sure how that is going to relate to the fore/aft position of the mount on your transmission, but you will need a spacer of close to 1-5/16” in height to account for the trans mount pad elevation differences like we did in the LS swap application.

skinny z

Thanks for that. It's beginning to look like the struggle of building a dual exhaust for these cars has just become a whole lot easier.
I will assume the new headers will be stainless steel like the rest of the exhaust. That said, at one time I believe it was suggested (here) that a mild steel version of the exhaust may be produced. Anything further on that front?

toddoky

I’m not sure they will become available in mild steel or not eventually, but they will initially be released as a 304SS offering only. Yes, the crossmember does simplify things in the exhaust routing department greatly.

Chuck!

toddoky -- any chance you're looking to release a system for high HP LS swap applications (2" header primaries + dual 3" exhaust)?

toddoky

There is nothing currently on the development schedule in regards to such products, but things get added on a constant basis, so you never know what might happen in the future.

TORN

iTrader: (17)

Any sneak peak pics of the new Hooker Blackheart 3rd-gen SB headers?

toddoky

I wish I could, but I’ve been disallowed by Holley management to post preview images for about a year now...I can say that they very much like the Hooker Blackheart 3rd gen LS swap headers, so I think you SB Chevy guys will be pleased. It shouldn’t be much longer for them to be released.

Louis Q

any news on those blackheart sb headers? and i have a 700R4 is there any crossmembers i can use to make the fit work or what would be the best way to install this true dual exhaust i dont mind the money i just dont want to start cutting

thanks

toddoky

I’ll check into the status of the headers for you tomorrow. I’m regards to your 700R4 question, you can source the extension housing that GM used on the transmissions in the B-body Caprice cars in the past. Those extension housings have a mount provision in them that locates the mount in the same approximate location as a TH400 or 2004R transmission, which will let you utilize the Hooker Blackheart transmission crossmember by making a custom adapter for it to pick up the transmission mount.

skinny z

That would be this one.

toddoky

Louis Q, the last bits of production support tooling is being completed for the Hooker Blackheart 3rd-gen SB headers now and they will go into production following that. I would guess by what I know our processes to be that it will be about another 30-45 days before you see them become available.
