Things to Consider Before Buying

Before you click that "buy" button, there are a few things you need to think about to make sure you're making the right choice for your engine build. It's not as simple as just slapping in some new lifters and calling it a day. Here’s what you need to keep in mind:

1. Engine Specs: What are the specs of your engine? What kind of camshaft are you running? What's the intended use of the engine? These factors will all influence the type of lifters you need. A mild street engine will have different requirements than a full-blown race engine.
2. Valve Springs: Are your valve springs compatible with the lifters and camshaft you're using? Mismatched valve springs can lead to valve float, reduced performance, and even engine damage. Make sure your valve springs are properly matched to your lifters and camshaft.
3. Oil System: Is your engine's oil system up to the task? High-performance engines require adequate oil pressure and flow to properly lubricate all the components, including the lifters. Consider upgrading your oil pump or adding an oil cooler if necessary.
4. Installation: Are you comfortable installing the lifters yourself, or will you need to take your engine to a professional? Proper installation is crucial to ensure the lifters function correctly and avoid any potential issues. If you're not confident in your abilities, it's best to leave it to the pros.
5. Budget: How much are you willing to spend on lifters? LS7 lifters from Michigan Motorsports can range in price, so it's important to set a budget and stick to it. Keep in mind that you may also need to factor in the cost of other components, such as valve springs and pushrods.

Installation Tips and Tricks

Alright, let's talk about getting these lifters installed correctly. Proper installation is key to ensuring your engine runs smoothly and avoids any potential headaches down the road. Here are a few tips and tricks to keep in mind:

• Soak the Lifters: Before installing the lifters, soak them in clean engine oil for at least 30 minutes. This will help lubricate the internal components and ensure they are properly primed before starting the engine.
• Follow the Torque Specs: When installing the lifter retainers, be sure to follow the manufacturer's torque specs. Overtightening can damage the retainers, while undertightening can cause them to come loose.
• Check Pushrod Length: After installing the lifters, check the pushrod length to ensure proper valve train geometry. Incorrect pushrod length can lead to valve train noise, reduced performance, and even engine damage.
• Use Assembly Lube: Apply assembly lube to the lifter rollers and camshaft lobes during installation. This will help reduce friction and wear during initial startup.
• Prime the Oil System: Before starting the engine, prime the oil system to ensure the lifters are properly lubricated. This can be done by using a priming tool or by cranking the engine with the ignition disabled.
