David Freiburger spends this episode of Roadkill Extra doing something Roadkill rarely does: teaching, not wrecking. Compression ratio sounds like a spec sheet footnote until he breaks down exactly how bore, stroke, chamber volume, and camshaft timing all feed into the number that decides how much power an engine can make before it starts destroying itself. It’s the kind of explanation builders bookmark and come back to before their next build. Find out what the calculator actually needs to get right.

David Freiburger’s 1970 Dodge Super Bee sat filthy in a barn for 36 years before he finally rescued the exact car he’d been chasing since he was a teenager. In this installment, decades of accumulated grime finally comes off before reassembly around a budget 440 he already built and dyno-tested. Watch to see just how much thirty-six years of neglect really left behind.
Compression ratio is the number every engine builder throws around, and the one most can’t actually explain past ‘higher is better.’ Roadkill Extra host David Freiburger breaks down exactly what it measures, why pushing it too far invites engine-destroying detonation, and how builders actually raise or lower it on a real engine. One top comment argues the fourteen-minute video teaches the concept better than a university engineering class. Here’s what actually earned that praise.
David Freiburger and Steve Dulcich built The Red Duster, a budget 1971 Plymouth Duster with a 360 and a four-speed, on Roadkill Garage — then Freiburger hit the road to visit Dulcich once the wrenching wrapped up. A 2023 Dodge Challenger Scat Pack giveaway rides along with the build. It’s a low-buck muscle car with a surprisingly high-value payoff.
David Freiburger and Mike Finnegan head to a Colorado junkyard with roots back to 1959 and walk straight into a genuine rescue project: a 1969 Ford Mustang Mach 1 that had been sinking into the same spot since around 1980. Thirty-seven years of neglect usually means a car is done for good — this one had other plans. The team’s approach to getting it running again is classic Roadkill. Watch how far a nearly-forgotten Mach 1 can go.
Steve Dulcich and David Freiburger sit down to plan a small-block rebuild for a 1970 Dodge Challenger after its factory 318 got wrecked in a prior Roadkill Garage episode, and the conversation turns into a full history lesson on Chrysler’s LA-series V8. Viewers in the comments call it some of the best pure engine-nerd talk on the channel, right down to warnings about mixing cast and forged cranks. It is dense, it is technical, and Mopar fans cannot get enough of it. Watch to see what they land on for the rebuild.
