David Freiburger genuinely forgot he owned this 1970 Plymouth Duster until it turned up buried in dirt on a California grape farm belonging to Engine Masters editor Steve Dulcich. What followed was a five-day sprint to stuff a salvaged 440 big-block into the car, complete with hammered-on headers and a trunk painted before the engine even ran. Longtime fans still call it the best episode Roadkill ever made. Watch the full build and burnout below.
Engine Masters puts a stubborn garage myth to the dyno: does a 3-inch exhaust really outperform a 2.5-inch system, or does it depend on what’s bolted to the other end of the pipe? Real back-to-back testing, presented by AMSOIL, replaces forum arguments with actual horsepower curves. Over six million viewers have watched the results, and builders are still citing them years later. See what the numbers actually show.
During Buck Hinkle’s Vintage-class dyno pull at Engine Masters Challenge 2016, a cracked oil filter gasket sprayed pressurized oil onto red-hot headers and turned a routine run into an open flame in seconds. Host Steve Dulcich’s unbothered reaction became almost as memorable as the fire itself. It’s a reminder of how quickly a small, cheap part can end a competitive engine build’s day. Watch the moment a dyno cell nearly became a bonfire.
