Got questions? We’ve got the answers—the Summit Racing tech department tackles your automotive-related conundrums. This week, we’re dialing in timing and straightening out a few cam/valvetrain issues.. C.S. • Currie, NC Q: I have a 1967 Ford Fairlane. It’s equipped with a 1968 390 GT engine that’s bored .030 inches over. The engine uses the
Learn about roller and flat-tappet camshafts. Learn about the differences between drag racing and towing applications for choosing the best camshaft for your vehicle. Better understand the duration and lift numbers for your ride. Hear why a mild camshaft is most likely the right choice for you. All by watching this Summit Racing Quick Flicks
