Your spark plugs are like a cipher. And to read a cipher code, you usually need a cipher key. That’s what this is—a cipher key that is going to help you “read” your spark plugs and understand what they’re telling you about how your engine is running. Is your engine running too rich? Too lean?
Automotive suspensions have come a long way since the original muscle car era of the 1960s and early 70s. Today’s shock technology allows for tuning your suspension for maximum handling and control; and the tubular steel components offer a better, stronger alternative to stamped steel parts. Fortunately, suspension manufacturers have started to make modern suspension technology available
Engine rebuilds come in many different varieties. Take a look at the vast array of engine rebuild kits available through Summit Racing, and you’ll see the contents vary from kit to kit. Some include things like gaskets, bearings, and piston rings. Others are more comprehensive and also come with pistons, timing set, and a camshaft.
“Upgrading even the most basic engine parts like engine bearings can give you a great performance advantage,” said Summit Racing tech expert Norm Koval. In this short tech tip video from Summit Racing and Powerblock TV, you’ll hear Koval explain how specialty coatings which reduce friction, and include certain machined design elements give performance bearings
Q: I bought a 1988 Camaro IROC-Z with a 350 TPI (the second I have owned). My question is about engine running temperature. When the car is not moving faster than 30 miles-per-hour, the temperature climbs over 200 degrees, and the fans won’t turn on until the temperature reaches 240 degrees. Both of my IROCs did this.
Editor’s Note: The following letter is in response to an answer in a previous column concerning whether to go with a 5.3L LS engine or a larger 350ci small-block Chevy. You can read Jeff’s original answer here. Prices reflect April 2016 figures per Summit Racing and, given the context/purpose of the article, have not been updated.
Every once in a while a product comes along that’s not only good for your vehicle and good for your comfort, but is also somewhat easy to install. It’s rare indeed that a product can look good, work well, and slide in exactly like the instruction sheet says it should. Bestop’s Trektop NX is such a
In Part 1 of our All About Stall series, we shared three factors to consider when choosing torque converter stall speed range: engine setup, vehicle weight, and rear gear. When considering engine setup, the tech experts at Summit Racing suggest using the camshaft powerband as a starting point for choosing stall range. However, there are
A high-torque starter can deliver the extra starting power you need to turn over a high compression engine. In the case of a high-torque mini-starter, you get that extra power in a more compact package for increased ground, oil pan, and/or header clearance. The advantages are clear, but there are some important steps you need to take
Q: I was wondering if you could answer a few questions for me: Could low oil pressure (15-20 psi) spin a main bearing or otherwise ruin an engine? How can you avoid low oil pressure? How long would it take for low oil pressure to spin a bearing? A: Here are the answers to your questions in
