On the exhaust system side, run a 3-in. system only if you have a single pipe from the catalytic converter back. If you have dual pipes from the converter, we recommend using a 2½-in. pipe.
It doesn’t matter how many times Miffy bathes herself—if she’s furry, your seats will be too. And let’s face it, dogs will go out of their way to get nice and muddy before it’s time to hop in your car. A good seat or floor cover can prevent paw prints from “customizing” your interior. They’re durable too, and can keep sharp claws from poking holes or scratching panels. Depending on where your pet rides, you can get individual seat covers, full bench-style covers, and liners for a rear cargo area.
The factory heads are based on the LS3 heads. However, they have a flow vane in the intake port. This helps emissions and idle stability, but reduces flow. CNC porting the heads is common. This removes the vane and improves airflow by about 70 cfm. Aftermarket cylinder heads are another option. These heads will flow even better than ported stock heads and have thicker deck surfaces to withstand more boost.
Upgrading the camshaft will require the matching valve springs. Titanium retainers are also recommended. They will reduce the valve weight and prevent valve float. The trunnion bearings in the stock rocker arms are a known weak point. We strongly recommend a trunnion upgrade kit. Swapping in a set of full roller rockers is another option.
The cooler the fuel rails are, the cooler the fuel inside them will stay, which helps to improve injector performance and prevent power loss. With the AutoRama show rolling into Dallas, TX, auto photographers had their cameras ready and we were fortunate to get our hands on some of their work.
I would like to get about 350 hp out of the new engine and run in the 13s. Is this possible with my combination? Your crate 350 should be okay for use with a TPI system. We recommend checking the engine’s camshaft specifications. Most “computer-friendly” cam profiles are no bigger than 214-222 degrees duration at .050 and .450-.460 inches of lift with 112-116 degrees of lobe separation. If the cam in the new 350 is much over these figures, you should consider a different camshaft to ensure compatibility with the IROC’s computer.
The Stock final was an E/SA heads-up competition that pitted Larry Gilley and his ’69 Dodge Dart against Ryan Mangus in his ’70 Camaro. Gilley launched off the starting line in .009-second to Mangus’ .012 start to initiate a thrilling race. Gilley got there first with a 10.627, 121.27 win over a 10.664, 122.73.
Unless your pet is a kangaroo, they might struggle to get into a vehicle with a high deck height, like many trucks and SUVs. That’s where pet ramps come in handy. They’re available in a wide range of sizes and most fold compactly and can be stowed away, so you can bring the ramp with you.
