Re: Hooker Blackheart 1967-72 C10 Truck LS/LT Swap System Info Thread
So how did the fit up go on the 64 you had in the lab in January? Have you been able to see what parts of the 67 to 72 stuff will cross over?

Re: Hooker Blackheart 1967-72 C10 Truck LS/LT Swap System Info Thread
Yes, we worked through the validation and design process on the 63-66 C10 application and I can report that there will be specific engine mounting brackets and headers that will be released for them that will be based on the use of the same motor mounts we used for the 67-72 C10 shown in this thread. The transmission crossmember will be shared between the application as will the exhaust systems after a small revision is made to the rear tailpipe hanger brackets.

Is there a time frame for this? Getting close to time to start on the 65.

Re: Hooker Blackheart 1967-72 C10 Truck LS/LT Swap System Info Thread
Hello Jimmy. If you are in immediate need of parts, those specific Hooker Blackheart parts won’t be helpful to you. They have made it past the prototyping stage, but all of the pre-production tooling, documentation and first production run requirements that are still in-process will put their availability out somewhere around 4 months from now.

Re: Hooker Blackheart 1967-72 C10 Truck LS/LT Swap System Info Thread
Hello, do you make a downpipe to go from Hooker ls cast manifolds to the blackheart exhaust system? I have been all over the website and summit but can't find one. found several for cars but not 70 c10. Also how is the clearance for shifter linkage with the headers. the pics above don't show a steering column and linkage. thanks

Re: Hooker Blackheart 1967-72 C10 Truck LS/LT Swap System Info Thread
Thank you for the reply and will be watching for the info to come out. on a side note has anyone used this exhaust system along with nolimit parts such as shock relocation kits and adjustable panhard rod system? looking at pics things might get tight. thanks for any input.

Re: Hooker Blackheart 1967-72 C10 Truck LS/LT Swap System Info Thread
From the photos I looked at of both of those No Limit parts during my development research I’d have to say that neither of them would be usable with the Hooker Blackheart exhaust systems due to them needing to occupy the same physical space as the exhaust system tubing in multiple areas. The driver side over-axle tube will only clear the stock panhard bar frame anchor bracket used on the 1965-up trucks.

While I'm checking in to this thread I thought I post some pics of the 1970 C10 development truck in its current state of assembly.

Re: Hooker Blackheart 1967-72 C10 Truck LS/LT Swap System Info Thread
72MARIO; thanks for the update, I appreciate it.
Toddoky; that’s a good looking stepper, thanks for sharing. What size wheel/tire combo is it running?

Re: Hooker Blackheart 1967-72 C10 Truck LS/LT Swap System Info Thread
I'm not sure about the wheel/tire package sizes used as I had no involvement with the assembly of the truck. I will have to provide the info at a later time as the truck has left the engineering lab temporarily, so I don't have access to it to be able to gather that information off of it.

Re: Hooker Blackheart 1967-72 C10 Truck LS/LT Swap System Info Thread
The truck found its way back to the lab...the wheels are 18" x 8" on front and back and the tires are 225/60R on the front and 250/60R on the rears.

Re: Hooker Blackheart 1967-72 C10 Truck LS/LT Swap System Info Thread
I ordered some swap headers, BH13173, but was told today they have been discontinued and no alternative is available. Checked Holley's website and I don't see any long tube headers listed for LS swaps into 67-72 trucks. Already ordered the crossmember and exhaust system to ensure it all fit, but now no headers. Anyone know why?

Re: Hooker Blackheart 1967-72 C10 Truck LS/LT Swap System Info Thread
Just a FYI the exhaust system will not work with suburbans. I should have looked closer at my truck. I know it was not specified to fit suburbans. I bought it hoping it would work out
The pick up box floor is raised 3" above the frame behind the trailing arm crossmember. The suburban floor stays flat and the mufflers hit the floor. Between the missing hanger from the exhaust kit and hours on the phone trying to get the missing hanger I am going to have a ton of hours into this system. What solution did your team come up with for the parking brake cable ?

Any update on the engine stands for a 67 with wide upper frame rails?

Re: Hooker Blackheart 1967-72 C10 Truck LS/LT Swap System Info Thread
They have evidently made it onto our shelves and are awaiting a press release to be sent out to be listed on the Holley website. I would guess they will become visible by the end of the week.

Re: Hooker Blackheart 1967-72 C10 Truck LS/LT Swap System Info Thread
Wow the side exit blackheart system has increased over $200 in price during the couple of months that I've been waiting on the release of early frame stands.

Re: Hooker Blackheart 1967-72 C10 Truck LS/LT Swap System Info Thread
Make sure you are comparing the price based on the same type of material. The exhaust systems are available both in 409SS and 304SS and there certainly is a cost/price difference between those material choices.

Re: Hooker Blackheart 1967-72 C10 Truck LS/LT Swap System Info Thread
No I'm comparing the same 409SS material. A few weeks back the rear exit and side exit systems were priced the same. The side exit system has increased significantly in price while the rear exit has remained the same. I really like the system (side exit preferbly) and felt it was fairly priced, perhaps I'll go for the rear exit before a price increase.
