Just reference points to who ever was thinking about the truck oil pan. Plenty of room to shim up with the 4l80e. Don’t know about other transmissions. Still running stock low tunnel. Ditching the Tejas and other mounts. These look like the way to go for my personal LT5 setup as they work for LS/LT swaps. Even fitted the stock AC bracket and compressor.

Stick your CTS pan on and all the clearance problems will disappear.

Engine angle 3 degrees back, truck pan clears with just about 1/2”. Still hangs below crossmember about 1.75”. If you have stock height truck you shouldn’t have a problem. Of course the CTSV plan will clear. I still have about 3/4” of tunnel clearance with the 4l80e.

Toddoky- the instructions show the hanger for the mufflers bolting to the crossmember! Does this come in the kit? Along with the other hangers not show with the kit??

Yes, all the required hangers are included in the kit. If they are not in your kit, you'll need to place a call to Holley Customer Service to get it remedied.

My set up is a little different than all of the Holley parts recommended as they were not available when I was installing everything. I have a 6.0 sitting on POL stands. 4L80e trans with Dirty Dingo cross member. Speed Engineering Long Tube headers. I had already cut the holes in my trail arm cross member and they are not exactly where Holley have theirs as mine sit closer to the frame rails, but are 4" holes.

The kit fits amazingly well from the rear bumper to the h-pipe. The quality of the kit and the brackets are top notch. I highly recommend the kit over having a shop build you a stainless system.

The downside, if you want to call it that, is hooking up the H-pipe section to the headers. The headers sit lower than what the pipe is. I ended up having a local shop fabricate up some pipe to make the connection. I wasn't too bad to have done, but I could not find a local shop that could do mandrel bends, so I had to go with the old press bends. At some point I will put cut-outs in and have mandrel bends installed.

If anyone wants pics of my install let me know.

Please post up your pictures, I have speed engineering long tube headers, and 4l60e! I’m wanting to order the 2.5” kit rear exit kit

Have you guys got anywhere with the other c10? I have a 66 c10 what 2.5” kit number would be a better fit over the ones for 67-72?? Also I have the cpp bend pan hard bar that runs from the driver side frame to the passenger side trailering arm! Will these kit clear the bar??

The exhaust system fitment is the same on the 65-72 C10's; the 63 and 64 models will need to have the rear track bar frame bracket relocated further back on the frame rail to where it is located on the 65-72 truck frames. Compatibility with the CPP bar shouldn't an issue as I validated the fitment of one during the prototyping of the exhaust systems. I don't recall whether is was of bent or straight geometry however. This image shows the clearance path I designed into the passenger side tailpipe to allow clearance for aftermarket track bars that attach to the bottom of the trailing arm.

I have no way to give you a reliable answer to that question as I have no involvement with the production side of the business. I do know from experience however that parts have ended up back in inventory far in advance of the dates posted on the website. Covid would most likely have had an impact on our production operations as is has with most other industries.

Looks very nice. I would move the right hand exhaust pipe to the right a bit from the trailing arm opening just a bit more.
Again looks very cool.

Seeing we can not purchase these can you tell us what mandrel bends for the over axle tail pipes we need to buy so we can make our own ?
I have been on the waiting list with Holley for 2 estimated shipping dates now and they never ship and I have waited months now for one and the next round is almost 5 months out, they told me before that 5 were in the works and I was # 3 on the list but they never get shipped and this is the last piece of my build that I needed to buy.

I can empathize with your frustration with the availability of these systems. Although I don't know the specifics, I know the Covid situation has created sourcing issues for Holley as it has for most other manufacturers across the country. The entire system is designed on a 4" center line radius, so that is what you would need to purchase if you want to make your own system in its likeness.

When I did my C10 I used mandrel bends from Summit. I try guesstimate the number needed but here in MN they have mandrel bends at the local Fleet Farm store. NAPA has them also. Dyno Max turbo mufflers. 3" at the header collector reduced to 2.5". I use band clamps not the typical muffler clamps. I typically start at the header and work my way to the end of the vehicle.

I have exhaust from the headers to the axle that are good and stainless, I just do not have the over axle tail pipes because I did not know what bends I would need.

If you are lacking only the tailpipes, I would estimate 6 U-bends to finish them out.

I would agree that your best course of action would be to go with an alternative source for your exhaust system if you are trying to be at a show with your truck on a specific date next month. I might make the same choice myself if I were in your shoes.

Re: Hooker Blackheart 1967-72 C10 Truck LS/LT Swap System Info Thread
 
toddoky. I went with the Blackheart setup straight out the back and I am now wondering what I could do to tuck the end pieces up in the rear step fenders some more so they can't be seen. When you stand at the side of the truck you can see the tailpipe too much between the rear of the step fender and the bumper. Can I get the end pieces only to have a local shop bend them (without a hanger)? Maybe I should have just ordered the ones that go out the side and modified them. Thanks for any help

toddoky 04-07-2021 10:22 AM

Re: Hooker Blackheart 1967-72 C10 Truck LS/LT Swap System Info Thread
 
The components are all run to build complete systems, so there is nothing left over to offer as individual parts once the production run gets boxed up and placed on the shelf.

I'm not aware of any aftermarket exhaust manufacturer that offers individual system parts for sale, but I can see where that would sometimes be of benefit to an end user such as yourself.

A competent fabricator can build you any sort of tips you want from U-bends; complete custom exhaust systems are fabricated that way in great numbers.

I ordered mine from Jegs this past July or August. Came the next week. Just wish I had gotten the side exit instead of the rear exit now. Very happy with the fit and sound. It is not a loud exhaust system. You can stand at the tailgate and still talk to someone :)

I ordered the BH13194, 2.5” rear exit 409ss! Called summit today automated message says kit should ship from manufacturer in 1-3 days! Hopefully it does, as now I would hate to cancel my order if it’s a few days out!

Do you have any pictures of the exhaust? The part where your not liking! I wish they would sell the kit in pieces as the 2 last pieces of the exhaust as would solve your problem, because to me that’s the only 2 pieces that look different in the kit! I could be wrong

I can confirm that the components within the different Hooker Blackheart exhaust systems are the same with the exception of the tips themselves and the rear hanger brackets.

Well that sucks, cause every time I’ve called summit about my order it says should ship within 1-3 business days from the manufacturer!!

I figured that, also what is the part number for the long tube headers that work with this exhaust kit? I ordered the 2.5” kit

Re: Hooker Blackheart 1967-72 C10 Truck LS/LT Swap System Info Thread
 
There is a new set of headers working its way through the release process that was specifically designed for the narrower frame rails of the 1963-67 C10 trucks. The design of those headers came about from discovering that the headers designed for the 1968-72 C10's wouldn't fit the earlier frame. That wasn't one of my personal projects, so I don't know when its release is scheduled for. Since you are installing a 2.5" exhaust system, you will need to perform some form of adapting to get it to connect to the long-tube headers since the collectors on them have 3" outlets.

I’m sorry to hear of your experience receiving an incomplete system. A call to customer service should get things corrected for you.

I received my Blackheart engine stands and cross member yesterday...this weekend, pull out the old tired 350 (71 lwb) hopefully dropping in the LM7/4L60E. A little worried that the truck oil pan won't clear, but some say it does. Fingers crossed.

Yes sir! Did that, been waiting for 2 days now to see if and when they plan on shipping all the hardware parts as option A or option B which is a whole other kit! Had plans with the exhaust shop Saturday to connect this kit with my speed engineering long tube headers! With postpone til I have everything on the truck, and reschedule an appointment with the exhaust shop
