Additional details regarding Miller's 365ci Engine Masters Challenge Olds include K&N filters, Hooker headers (PN 3107, with 1 3/4-inch primaries and 3-inch collectors), and Straightline Performance mufflers (PN 151300, 3-inch inlet and outlet). Dick Miller is one of two builders who signed up to enter Olds powerplants, and we're curious to see not only how this Olds does against the Chevy, Ford, and Mopar entrants, but also the other Olds! Dick told us, "We've got the ability to make parts recommendations, sell the right parts combinations, and work directly with our customers to design and build Oldsmobile engines to best suit their specific needs. This engine is typical of what we do here; every part has been carefully researched and modified to perform to as well as possible. If an Olds enthusiast wanted more performance, he should call me and I'd work with him personally. Hell, even if they're restoring a rare Oldsmobile, I can help them get the correct parts they're after." Thanks for information, Dick, and we'll see how your extensive research plays out against the big dogs on dyno day!
