Hooker Blackheart 1967-72 C10 Truck LS/LT Swap System Info Thread

[toddoky]

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.

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.

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?

That part number has been obsoleted to make way for a new designed header for the same application, which should be close to be getting through its first production run in the coming month.

Good to know, thanks.

Will the existing exhaust system and crossmember designed to work with the old, work with the new design?

Does the new design offer clearance for wide frames, where old design apparently did not?

Can you pass along the new part number, as I'll order it when it's available.

Yes, the new headers will work with the other existing parts for this application. The new headers will fit 1968-87 C10 trucks and were designed for compatibility with our favored engine mounting set-up the uses 4th-Gen F-body type motor mounts. The 1963-67 wide frame trucks will be covered by their own specific header design/part number. I’m not permitted to post part numbers or photos of products until they are released, but I will do so in this thread as soon as I see that happen.
