Ringbrothers BULLY: the ultimate off-road blazer with 1.216 hp!

The Ringbrothers, known for their spectacular conversions of classic muscle cars like the Ford Mustang or the Camaro, now have one Chevrolet K5 blazer, an off-road classic from 1969 to 1972. The commitment culminated two years ago in the presentation of the “BULLY” at the SEMA Show, a project that over 8.500 working hours claimed. At the heart of the BULLY is a 6,8 liter LS3 eight-cylinder from Wegner Motorsports, supported by a massive 2,9 liter Whipple compressor, the crazy one 1.216 PS delivers. Although the Ringbrothers do not provide any precise information about the torque, the choice of the heavy one indicates GM 4LE80E four-speed automatic from Bowler, which is designed for up to 880 Nm or over 1.000 Nm, indicates considerable performance.
