Red Line '41 Willys Image


As much as Red Line Oil is about the latest technology and engineering, we pay much respect for hot rod heritage in the American scene as well. This blown '41 Willys Coupe represents that with old-school performance characteristics and a whole lot of power! A big-block Chevy with a BDS supercharger, 8.5:1 compression, Dart cylinder heads comes up with 700hp at 6000rpm and 750 lb-ft of torque and 5500rpm. It all gets protected by Red Line's 10W40 motor oil, which has plenty of ZDDP for the roller camshaft and roller rocker valvetrain. A Turbo 400 trans deals with the power through use of Red Line High Temp ATF and a Ford 9-inch with a Detroit Locker differential features Red Line Heavy Shockproof gear oil. Dominator Street Rods oversaw construction of this Willys, orchestrating a Sid Shaver interior, Billet Specialties accessories and accents, and an amazing paint and body process that includes DuPont Hot Hues Firethorn Orange and mixed Lemon Glow in the flames and our Dupont "Red Line Red" with a hint of pearl on the body.
