With corrosion from oxygenated pump fuel wreaking havoc on automotive plumbing systems, car owners and auto techs are turning to more durable line solutions like polytetrafluoroethylene (PTFE) braided hose. It’s not overly difficult to assemble, but it helps to have the proper tools and instruction. In today’s video, Summit Racing tech adviser Carl Pritts will introduce
Q: I have a 1973 Ford Ranchero. It has a stock 302 engine with a two-barrel carburetor, a C-4 transmission, and an open-type rear axle with 3.08 gears (I think). The only modifications are headers and a dual exhaust. At about 50 miles-per-hour and above, the engine starts to break up. Acceleration up to 50 is
Editor’s Note: We’re back with Part Two of Project LS Next, a 440 cubic inch LS engine based on Dart’s LS Next iron block and built by Mike Mavrigian at Birchwood Automotive. In Part One, we covered the block prep, the rotating assembly, and camshaft installation. This round is devoted to the oiling systems, valvetrain,
Spring rate is a key factor in choosing the right springs for your suspension system. Spring rate is defined as the amount of force it takes to compress a spring one inch. A 200 lbs./in. linear spring, for example, will compress one inch when a 200-pound load is placed onto it. If another 200 pounds is put onto the spring, it will
Q: I have a Ford truck with a 390 engine. I had the heads redone and installed a new cam and lifter set, true roller timing chain, valve springs, single plane Edelbrock intake, adjustable rocker arms, and headers.

Tire tread wear comes in many forms. The wear pattern on your tires may be normal or it could be the result of an underlying issue. For example, you may be over-inflating your tires or your tire pressure could be too low. Or, perhaps your vehicle could use an alignment. A quick visual inspection using the
Kevin Tetz is a certified auto body repair man, TV personality, and creator of the video series Paintucation. Tetz recently put together a series of short tech videos in conjunction with Summit Racing to share some of his paint and body secrets. Okay, they’re not exactly secrets, but the videos will show you the right way to align
Q: I own a 1966 Pontiac Lemans with a 1970 400-cubic-inch engine, a two-speed automatic, and an open rear axle. I recently rebuilt the engine to stock specs, adding a Crane cam (290-degree advertised duration, .454-inch lift), an Edelbrock Performer intake, and a 600 cfm Holley.
