TCI Machined and Forged Flexplates Will Live Behind Your High-Stress LS Engine
High RPM and high-stall torque converters put a lot of stress on drivetrain components, including the flexplate. A TCI Machined or Forged Flexplate can handle what your LS engine dishes out.
The flexplates are SFI 29.1 or SFI 29.2-approved depending on the application. They’re made from precision-ground, 1/4-inch thick A514 or A36 steel plate that is much thicker and stronger than the OEM flexplate material. The 168-tooth flexplates have a heavy-duty ring gear for added strength.
Summit Racing also carries TCI’s Lightweight Forged Flexplate for LS1 engines. Built to withstand 12,000-plus RPM, the SFI 29.2-approved flexplate has CNC-milled pockets and lightening holes to reduce rotating mass and decrease weight. Other features include a hobbed-on ring gear and robotic TIG-welded converter spacers.
TCI Machined and Forged Flexplates are available with six- and eight-bolt crank-to-flexplate configurations. There are versions to accommodate GM TH-350, TH-400, TH-700-R4/4L60, 4L60E, and 4L80E transmissions.

Driven Racing HR Series Hot Rod Motor Oil: The Right Oil for Your Engine
There is no single motor oil that works in all engines. That’s why Driven Racing offers its HR series line of hot rod motor oil. You’ll find conventional and synthetic oil formulated for weekend-driven classic vehicles, small block and crate engines, big block and supercharged engines—even blown marine engines and air-cooled engines.
HR Series Motor Oils have high levels of ZDDP (zinc) content for flat tappet camshaft and valvetrain protection plus corrosion inhibitors for long-term storage protection.
Driven Racing HR1, HR2, and HR5 Conventional Motor Oils are recommended for flat tappet and overhead cam engines in muscle cars, street rods, and vintage vehicles that require compatibility with OEM-style seals.
Driven Racing HR3, HR4, and HR6 Full Synthetic Motor Oils are recommended for higher-performance engines with looser clearances and higher operating temperatures. The oils offer superior temperature and oxidation stability and are ideal for engines requiring improved cold-start and thermal stability.
Driven Racing HR Series Motor Oil is available in 10W-30, 10W-40, and 15W-50 formulations. They recommend the 10W-30 for small block crate engines and street rods, 10W-40 for higher performance engines, and 15W-50 for big blocks, supercharged engines, and other high-load applications.

Turn Your Ford 7.3L Godzilla into a Fire-Breather with Components from Edelbrock and COMP Cams
Putting out 435 horsepower and 475 lbs.-ft. of torque, Ford’s 7.3L Godzilla is pretty beastly right from the factory. But you can turn your Godzilla into a Tokyo-stomping fire-breather with components from Edelbrock and COMP Cams.
Edelbrock XTS Intake Manifold
Edelbrock says adding its XTS Intake Manifold, a FAST 102mm Throttle Body, and a COMP Cams Stage 3 camshaft will turn your Godzilla into a 637 horsepower beast. The XTS manifold has short, tapered runners tuned to boost power from 2,500 to 7,000 RPM. Other features include a horizontal throttle body mount for better air intake routing, billet aluminum flanges for better sealing, and vacuum takeoff ports at the rear of the manifold for cleaner plumbing.
If you want to run the factory or aftermarket 80mm throttle body with the XTS manifold, Summit Racing carries Edelbrock's Throttle Body Adapter that positions the throttle body at the stock ‘upward facing’ angle.

Get the Classic Muscle Car Look Plus Modern Handling with Coker Firestone Wide Oval Radial Tires
When Firestone introduced the Wide Oval tire in 1967, muscle car guys shouted hallelujah. The bias-ply tire had a lower profile and wider tread than conventional tires of the era for better traction and improved handling and braking. The OEMs offered the Wide Oval as standard or optional equipment on muscle cars and pony cars through 1974. Watch this Firestone Wide Oval commercial from 1971 to get an idea of how popular this tire was.
As good as the Firestone Wide Oval was, its bias-ply design was eclipsed by modern radial tires. Fortunately for you classic muscle owners, Coker Tire decided to make the Wide Oval in a radial version. Designed and manufactured in the USA using brand new molds, they give you retro looks plus the handling, safety, and longer tread life of a modern radial tire.
