Rick Seitz is the owner and founder of GMEFI Magazine, and has a true love and passion for all vehicles. When he isn’t tuning, testing, or competing with the brand’s current crop of project vehicles, he’s busy tinkering and planning the next modifications for his own cars.
We've always had a huge amount of respect for the cars that Street Legal Performance (SLP) had tuned back in the day. Taking already potent performance machines from General Motors, and making them into rare ...
No stranger to the Delta platform, Steve has owned a total of three Cobalt SS' - including this 2007 example that he bought brand new in the Fall of 2006. What he did with his, ...
Understanding a need for a replacement for your worn, factory rubber differential bushings, BMR Suspension has released these polyurethane units for your '64-72 A-body, '78-87 G-body, and '91-96 B-body.
No matter where you stand on G-bodies, there's no denying the fact that they lent a small hand in bringing performance back to the modern marketplace. Whether or not they'll ever be highly desirable, valuable ...
Justin Kalwei's '94 Silverado is a Will Ferrell movie-inspired, turbocharged, LS-powered, evil red pickup truck straight out of a cartoon. The fact that it puts down 1200 hp and 1000 lb-ft to the tires makes ...
*Those guys at Nat Geo took the video down after being on YouTube for almost five years. If another one comes up, featuring either the 5th- or the 6th-gen Camaro, you can bet we’ll feature ...
Back in the mid-1980s, General Motors released a small, reliable, torquey, and somewhat powerful 4.3L V6 version of its small-block V8 as an economical and cost-effective solution to utilitarian vehicles. Being installed in a varying ...
If you're an '80s Turbo Regal owner, than you know how "problematic" the original Powermaster system can be - if you don't properly maintain it. That's why Highway Stars partnered with one of the most ...
Recently, we caught wind of YearOne's latest project, a LS-powered, pro-touring '66 Oldsmobile 442 that they're finishing up for one of their return customers.
We've decided to compile this year-by-year guide to help you, the reader, decipher the changes between the different styles, options, and features of the 5th-Gen. Chris Frezza of CamaroZ28.com will be adding his input, too!
The 2014 Holley LS Fest was such an action-packed event that it had us running in all directions. Everything from drifting GTOs to 9-second CTS-Vs were in attendance, and just about everything we've seen had ...
Two red third-gen Camaros have recently been spotted by our colleagues at Autoblog, just outside (and inside) of GM's development center. We're quite curious as to what's under the hood...
UMI Performance has been hitting it hard with A- and G-body suspension components lately, and it makes sense. Because the GM A- and G-body cars of the late '70s and 1980s are quickly growing ...
Hooning - a term that teenagers and 20-somethings use, when they're acting a fool behind the wheel of whatever car they bought, borrowed, or stolen. But then again, we'd be lying if we said we ...

The video makes it a point to highlight the special and unique features of the GNX over a "standard" Grand National; such as the ceramic turbocharger, larger wheels and tires, flared wheel arches, and the ...
Lingenfelter Performance Engineering (LPE) has released its NCC-002 Nitrous Control Center, which doubles the solenoid driver capacity of the original NCC-001 controller for both nitrous and fuel outputs.
With several performance packages available from LME, including two that bring a Magnuson supercharger along with them, there are plenty of avenues Chevy SS owners can take with their cars.
This is what happens when you compare a fast car to one with 700 horsepower. Hennessey claims the package is actually putting grown 708 rwhp, and that they will only build 100 copies for 2014.
We hand pick four interesting vehicles for this month's Reader's Rides. While it's purely coincidental that there's two Camaros and two B-bodies, each has their own unique story.
Camaro fans are gearing up for what could very well be the best Camaro yet. With a rumored weight loss and more power inevitable from the projected Gen-V LT1 V8, things are already looking great ...
DeatschWerks just dropped another bomb on us. Recently we've told you about their 350iL and V2 DW300 fuel pumps, but now, they're releasing their 1500cc DV2 EV14 injector.
Good for 650 hp and 650 lb-ft., this thing is simply going to fly! And since the third-generation CTS is lighter than the previous car, we can only assume that the platform changes made from ...
We ran across this short video, featuring "Smurfkiller's" 2014 ATS Turbo sedan. Featuring an ACS front splitter and side skirts, as well as Lenso EX20 wheels and massive Brembo brakes, this little Cadillac has a ...
