Add some bling to your Oldsmobile engine! When I was working on my ’73, I realized I needed high-quality block-off plates for the choke heat riser and the fuel pump—so I designed them myself. Now, you can upgrade your classic engine with these custom machined block-off plates, crafted with precision and care.
Product Features:
Material: Made from premium 6061 billet aluminum, known for its strength and corrosion resistance.
Finish: Brushed for a clean, modern look that stands out under the hood.
Customization: Choose from the designs shown or describe your custom needs, and I’ll do my best to create one tailored for your project.
Complete Package: Each plate comes with a set of stainless steel hex bolts and a laser-cut Fel-Pro rubber fiber gasket, engineered to handle oil, coolant, and gasoline without breaking a sweat.
Handcrafted Quality: Every block-off plate is handmade in the backwoods of mid-Michigan, ensuring attention to detail and craftsmanship.
Whether you’re restoring, upgrading, or simply customizing your engine, these block-off plates offer both function and style. If you need something specific beyond the options shown, just reach out, and I’ll let you know what’s possible.
