“Electric cooling fans are the way to go for freeing up horsepower and for keeping your engine cool at all driving speeds,” says four-time NHRA Pro Stock champ Greg Anderson. In this short tech tip video from Summit Racing and Powerblock TV, Anderson will explain how CFMs determine whether a large single fan can be
Q: The 350 Chevy in my ’73 Pontiac LeMans needs a new bumpstick, and I’m looking at COMP Cams Extreme Energy XE274-10 camshaft (part #CCA-CL12-246-3). I plan on running a TH-350 transmission with a 3,000 rpm stall speed converter and a 3.42:1 rear-end ratio. Plus, the engine has a 10.0:1 compression ratio, and the car has
Horsepower is the holy grail we all love to chase, but who says you have to be uncomfortable doing it? While we worked to upgrade the performance of our 1978 Camaro project, we also had an eye on upgrading the dumpster fire of an interior into something that we actually wouldn’t mind spending some time in. Over the
[portfolio_slideshow id=56479] When it comes to pistons, the most common arrangement you’ll encounter makes use of three piston rings — compression, second, and oil. Today, we’re turning our focus to the areas of the piston most associated with the rings: the ring lands and grooves. Piston ring lands are the areas of the piston between the piston rings.
Everybody that has Ford blue running through their veins loves the 5.0L Coyote. And with good reason—a production Coyote makes 435 horsepower and 400 ft.-lbs. of torque, and they’re readily available in crate engine form. But that doesn’t mean the older 4.6L Ford modular motor has to choke on the Coyote’s dust. In fact, Trick
Q: I am converting my rear suspension to a coil-over system, and I see spring options vary by the weight of the car. What is the most cost-effective way to determine the weight of my car? A: Many towns have a public scale you can use to weigh your car. If a public scale is not available,
I’ve got a Chevy small block 350 with a mild cam (I don’t know what the specs are – I bought the engine used), an Edelbrock Performer intake, Holley 750 vacuum secondary carburetor, and headers. All of this is in my ’72 Chevy pickup. The truck runs great except for a stumble when you first
All things being equal, a lightweight race car will always be quicker and faster than a heavy one. But even if you can’t take pounds out of the car, it’s a really good idea to think carefully about how weight is distributed. Weight distribution is extremely important, and mostly misunderstood. Chassis builder Jerry Bickel says weight distribution
The two most common types of automotive brake systems are drum brakes and disc brakes. Drum brakes have been stopping vehicles for much longer than disc brakes, but as horsepower and vehicle speeds grew in the 1960s and ’70s, the need for more stopping power prompted automakers to transition more toward disc braking. Disc brake
Q: I have a 1984 Cutlass with a Chevy 350, flat top pistons, stock cylinder heads, .448-inch lift cam (350 horsepower grind), Edelbrock Performer RPM intake with a Performer 600 cfm carburetor, MSD 6A ignition, headers, and a dual exhaust with Flowmaster mufflers. The rear-end is a stock 7.5-inch GM 10-bolt with 2.42 gears. I
