You will also need engine assembly lube, which is included, and potentially other related components like gaskets and seals depending on the condition of your engine. It's always a good idea to consult the included instructions and manufacturer recommendations.

Is this camshaft legal for use in California?

Product Details

If you're looking to wake up the performance of your Oldsmobile V8, this COMP Cams camshaft kit is a solid option. This kit is designed for a range of Oldsmobile engines, from the 260 all the way up to the 455, and is a popular choice for street machines and even some marine applications like jet boats.

The Magnum 230/230 hydraulic flat tappet camshaft in this kit offers a noticeable bump in performance. It's built for engines with a 2200+ stall torque converter, and you'll want to pair it with headers and lower rear-end gears to really let it breathe. Expect a rougher idle with this cam, which is typical for performance grinds like this, but it translates to improved throttle response and power. The kit comes complete with the camshaft, lifters, a timing chain set, assembly lube, and decals, so you have the essential parts to get the job done.

This kit is a great way to get more out of your classic Oldsmobile engine. Just remember that it's not CARB approved, so it can't be shipped to California.
