Overview:

The Holley GM LS7 Modular Hi-Ram Intake Manifold is introduced as a cost effective alternative to fabricated sheet-metal for high-performance applications where induction system height is not limited. Coupling this Hi-Ram intake with the high flowing LS7 style cylinder heads has outstanding potential for N/A and forced induction applications at a budget-minded cost. Aggressive, bold, race-bred styling will make bad intentions clear for drag race, muscle car, marine, off-road, sandrails, pulling trucks, track, street-rod applications and more!  The base is designed to be modular in configuration to accept a wide range of carbureted and EFI tops and to be attractive to builders and fabricators as the foundation for custom induction systems.  Runner length and the tapered cross-section designed to perform well for a wide range of engine configurations  EFI fuel rails are machined for -8AN O-ring Fittings with passages large enough to accommodate high fuel flows and dampen pressure pulsations in the fuel system and come standard with EFI Hi-Ram kits.  Cast aluminum construction.  Intended for use on N/A or forced induction engines in the 6.0 to 7.0+ liter range, max power at 7000-8000+RPM.

⭐️⭐️⭐️⭐️⭐️ Solid wallet. No nonsense.
Color: Black, Color: Black
This Timberland wallet is a straight-up beast. The leather feels premium the second you touch it — not that cheap stiff stuff, but real, rugged leather that actually smells and feels like quality. It’s slim in the pocket but somehow holds everything: cards, cash, ID, no problem. No bulky mess, no awkward pocket bulge. The RFID security is a serious upgrade. Knowing your cards are protected while you move around gives peace of mind you didn’t even know you needed. It’s like having a silent bodyguard for your money. Stitching is clean, edges are solid, and the design is straight classic — masculine, sharp, and built to last. This isn’t a “replace next year” wallet… this is a “break it in and ride with it for years” kind of wallet. If you want something tough, classy, and functional without looking like you’re trying too hard, this is it. Timberland didn’t miss with this one. 🔥 Buy it once. Carry it forever.

Does not block RFID scanners
Does not block RFID scanners. I literally scan my badge into work every day through it. Other than that, they are nice wallets, but only last about 3 years before the leather starts crumbling off. This is the second one I have bought. 2 Stars because they only last about 3 years and does not block RFID scanning as advertised.

2nd time purchase in 7 years.10 stars!
This wallet design is fantastic. Compact, front or back pocket use. Has a ton of storage even though it doesn't look it. Last one lasted 7 years of abuse and use. I ordered 2 in case these never get made again. Grab one, best wallet and real durable leather, not fake leather.
