COMP Cams - Xtreme Auto/Marine Camshafts

OE Hydraulic Roller

PLEASE NOTE: BBC - 1965-66 396 c.i. models have an oiling groove in the rear journal. The listed part numbered cams will not fit these models.

This cam performs well in marine and street applications. The 112 ° Lobe Separation is often used in marine applications due to their "wet exhaust" system, it prevents the water in the exhaust from getting into the engine.  As the possibility of water in the intake is reduced, so are exhaust gasses.  This is called "reversion".

Why should you care? Chances are you want more precise fuel control, throttle response and efficiency. Here are some other benefits of reduced "reversion":

  • Broader Powerband : A 112 LSA tends to offer a more balanced power delivery across the RPM range, great for street-driven cars where you want a good mix of low-end torque and top-end power.

  • Improved Vacuum : Offers better idle vacuum than camshafts with tighter LSAs (like 108 or 110). This characteristic makes it suitable for engines that rely on vacuum-driven accessories, like power brakes. More vacuum typically leads to smoother idles.

  • Smoother Idle : In performance street engines, this can make the vehicle more pleasant to drive in stop-and-go traffic or at lower RPMs, without sacrificing too much performance at higher RPMs.

  • Better Emissions and Fuel Economy : The reduced valve overlap helps with emissions control and fuel economy, which might be important if you're building a car for the street and need to meet certain environmental regulations.

This cam is a real gem for big-block Chevy (BBC) engines, especially if you're into street rods. It's the perfect balance of power and durability—enough grunt to make you smile every time you hit the gas without beating up the valve train. This cam really shines in 496 BBC engines or bigger, where it becomes more manageable, but still packs a punch. If you're running a 454, you'll need around an 11:1 compression ratio to make it sing, but in a 496 or larger, you can get by with about 10.5:1 and still get solid results. Now, if you're working with a 540 to 572 engine, this cam really comes into its own. A compression ratio of 10.2:1 or better, and you're off to the races—literally!

What makes this cam special is its profile. We used to run a cam in our 555 engines with similar lift and duration, but with a 110-degree lobe separation. It made decent power, but when we switched to this new Comp Cam with a 112-degree lobe sep, we saw about 35 more horsepower across the board. Plus, that 112 lobe sep gives the engine a bit more breathing room, making it a safer setup overall.

We've tried this cam in over 600 BBC engines, from 496 all the way up to 632, and it's hands down our most popular choice. Comp Cams really nailed it with this one. If you're running a smaller engine or a lower compression ratio, we've got another cam that's a bit milder and gives better low-end response. But if you're building a 496 or bigger, and you want the best mid-to-top end power without breaking the bank on valve train components, this cam is the way to go.

And don't worry about longevity—this cam won't give you trouble if you're using decent hardware. Just make sure you pair it with a high-quality lifter, like our Max Effort Series. This cam's increased lift and duration will push the spring pressures up a bit, but that's what you want to keep everything stable and running smooth.
