![]() ![]() Recent testing comparing this crate motor to a junkyard 360 Magnum produced (not surprisingly) identical power results between the two (when identically equipped).įor this test, the 360 Magnum was equipped with the MI dual-plane intake, a Quick Fuel 750 Brawler carburetor and (to get things started) a set of factory cast-iron exhaust manifolds. It was up to the user to supply the necessary carburetor, distributor, and exhaust. ![]() Though a crate motor, the 300-hp Mopar Performance 360 was basically a production (assembly line) Magnum equipped with a dual-plane (Mopar Performance) M1 intake. Having sat idle for over 12 years, it was time the old 360 got some love. To answer this question, I took Westech Performance up on an offer to use their Dodge 360 Magnum crate motor from Mopar Performance. The question now, how much does a mild cam upgrade actually improve a 360 Magnum? Dodge Magnum Engine Initial Testing Toss in the fact that motors like the Magnum offered plenty of displacement (more than Ford or Chevy), ample head flow (for the time), and even a decent induction system (Kegger!), and you have motor basically begging for a cam swap. Believe me, they know these motors much better than the aftermarket, and could easily up the power ante if given the opportunity, but the cam choice must not only make the desired power, but also produce the desired idle quality, fuel mileage, emissions, and drivability, to say nothing of traveling 100K, 200K, or even 300K (or more) miles without complaint. Since power production is but one of the many design criteria of a factory cam, engineers are not free reign to add a few extra horsepower just for good measure. The reason for this is not some magic inherent in the fuel-injected, Magnum engine design, but rather the use of such mild cam timing on factory applications. The answer is that it responds very well to a cam upgrade. ![]() What does the Dodge Magnum 360 have in common with the GM LS engine family? In fact, what does a Magnum 360 (or smaller 5.2L 318) have in common with most every production small block? Even your daily driver Dodge Magnum 360 will respond to a mild cam upgrade!
