BlackHeart LS Swap Exhaust Manifolds-Rear Dump SBC Exit-Black - 8506-3HKRFor applications or projects where our standard LS swap manifolds (8501HKR, 8502HKR, 8503HKR series) don't quite fit and our "center dump" manifold (8504HKR) exits too far forward, our new rear dump and rear dump SBC exit cast iron swap manifolds have arrived.

For applications or projects where our standard LS swap manifolds (8501HKR, 8502HKR, 8503HKR series) don't quite fit and our "center dump" manifold (8504HKR) exits too far forward, our new rear dump and rear dump SBC exit cast iron swap manifolds have arrived. These differ in that they exit in a straight-down fashion much like a block hugger header but exit more toward the rear of the engine than our "center dump" manifolds. While almost the same as our 8505HKR line, the 8506HKR line shares the same driver side manifold, but has the passenger side exit of traditional Small Block Chevrolet manifolds (see 8525HKR) to guarantee fitment and possibly bolt up your existing exhaust when doing an LS swap. Cast out of the same Hi-Silicon-Moly Ductile Iron as most of our other lines, it will be tough to find a more durable, streamlined, and quiet exhaust option. Available in natural cast, silver ceramic, or black ceramic finishes, these manifolds are offered with flanges, gaskets, and flange hardware for connecting to our lineup of adapter pipe kits or for ease in fabricating your own custom exhaust.


Features:

  • Similar to SBC manifolds (8525HKR) but for Gen III/IV LS engines - same exit centerline but raised up 1.36-inches (driver side) / tucked in tighter by 0.625-inches on (passenger side)
  • 2.5-inch outlet diameter offers improved flow for maximum performance from a cast iron exhaust manifold
  • Tight tuck design that provides an exit between our standard swap manifolds and center dump manifolds (with passenger side SBC exit)
  • Intended for GM LS engine swap applications where durability, quiet operation, and leak-free sealing is desired
  • Available in Natural as-cast finish for a factory appearance, silver ceramic, or black ceramic
  • Cast from Hi-Silicon-Moly Ductile Iron to provide durability and corrosion resistance
  • Perfect complement to Hooker engine swap mount plates and Holley engine swap oil pans
  • Hardware included: Nickel plated steel mating flanges, MLS mating flange gaskets, and mating flange hardware

Worth it! Get it
Color: 1a. Clear, Size: 72"W x 72"L (Pack of 1)
I was pleasantly surprised at the quality of this shower curtain liner, especially for the price. We have bad water; turns other liners a pinky orange color. This has not turned colors, thick material. And I love how it has magnets to keep it attached to the tub to avoid water getting out onto the floor

Liner Filled with Lots of Light
Color: 1a. Clear, Size: 72"W x 72"L (Pack of 1), Color: 1a. Clear, Size: 72"W x 72"L (Pack of 1)
Basic liner with the added magnets so you are not constantly having to put your curtain where it needs to go to prevent water from your shower escaping and ruining your floor. Does exactly as it is intended and is clear so light is allowed into your shower where you can finally see things and not have to guess. Packaged folded and neatly into a plastic and thick wrapper and all you need to do is open, unfold and install with ease. It fit perfectly into the hooks and the length and width of my shower as the description accurately states. When the time comes for that monthly cleaning, just un-attach and throw into your washing machine and then air-dry and it’s brand new once more.

Easy to use. Stays sealed. Stays charged.
Size: 12 Combo Travel Size
I had previously bought packing bags in a store — the kind the you had to seal and then roll/squish the air out of one end of the bag. It really took 2 people to remove most of the air. I took them to Mexico, and they were just OK. I switched to these vacuum bags before our family ski trip. What a great purchase! This set includes multiple sizes, which worked well for both everyday clothes and bulkier cold-weather gear. They also fit well inside different size suitcases. One tip: Fill the bag, seal it shut, squish some air out, but then suck the final air out with the bag already inside your suitcase. You can "massage" the clothes and guide how the bag flattens out for a really efficient use of your suitcase space. The organization you can achieve is really impressive. The bag material and valve is tough enough to not allow any air leaks. The red "glides" they provide make sure the seal is solid and easy to achieve. And the system is simple enough that I suspect that elementary kids or people with lower dexterity could operate it (my teens certainly had no issues packing themselves). After returning home, I folded all the bag along their original fold lines, charged up the "sucky thing" (which still held 75% of it's charge after being used at least 20 times), and tucked it all neatly in our travel drawer, ready for our international trip next month. Great value. High quality. I'd even go so far as to say they're fun to use.

Travel bags
Size: 12 Combo Travel Size
Perfect packing bags. I’m using them for a trip to Alaska. The pump works easily . I tested them out and the air retention is perfect.? They are not too thick and will not take up space. The material seems like it will hold up without ripping. I will be using them often. They come in different sizes which work perfectly with different items.
