Ask Away! with Jeff Smith: Explaining 6-, 8-, and 10-Speed Automatic Transmission Gearing
I see where Summit Racing lists a TCI transmission that was originally a 4L80E – but they list it as a six-speed transmission. I’ve heard a little about this—did they add two more gears to the transmission? How is this different from the GM 6L80E transmission that is used in the Corvette or in the

I have a question. I am building a 427 cubic inch Dart motor with LS3 heads and a Kenne Bell 4.2L blower. I am looking for maximum horsepower out of this motor. What compression would you recommend? The blower is capable of 32 pounds of boost and it will run on E85. Thanks. – T.B. Wow,
Ask Away! with Jeff Smith: Should I Grind the Rough Surface Off of New Brake Pads?
I’m looking to buy some upgraded brake pads for my 2010 Chevy 1500 pickup as the brake pedal is starting to shudder on even light brake application.

I am building a 355 cubic inch small-block Chevy with AFR 1065 220cc Race Ready AFR heads, an Erson roller cam, and FiTech fuel injection.

I have a 429 Ford in a Torino I bought about five months ago. The previous owner told me it has a flat tappet hydraulic performance cam but he didn’t know the specs or much of anything else about the engine. Just recently, the engine started making a ticking noise that is the same as
Ask Away! with Jeff Smith: Making Valve Lash Adjustments with Little Engine Information
I just bought a cool ’70 Camaro with a 396 motor in it. The guy I bought it from said it had a “hot rod” camshaft in it. It idles like it has a big cam but it also ticks like there are one or two valves that might be loose. I don’t even know

I have a Pro Street Camaro with a big-block Chevy, TH400, Dana 60 and 4.30 gears. I just bought this car a few months ago. The gear ratio is what the previous owner told me it had. At approximately 50 mph I’m at 3,000 rpm. I’m running a 31-inch tall tire. How fast can I
