Engines » Cast Iron 6.0L

This is a stroked 6.0 cast iron block using a Butler Performance LS balanced rotating assembly featuring a Scat crank and rods with custom designed ROSS pistons with stainless steel top ring set from Total Seal . We used a very streetable BP LS custom grind hydraulic roller cam from Comp Cams. The valvetrain featured Comp Cams short travel lifters and Ultra Gold aluminum rocker arms. Butler chose the FAST 102mm cathedral port intake with FAST billet aluminum 102mm throttle body, FAST XFI EFI system, and XIM ignition box tuned by Travis @ Quillen Motorsports Engineering. This combo makes awesome power with daily driver street manners and extreme durability!

This mean Butler LS engine is the choice for the ultra popular LS swap, where people update their old small block with a newer fuel injected/self tuning LS platform. This engine will find its way into a 1955 Chevy Bel Air. Updates to this car will include a 5 speed transmission, Fab 9 rear end with a 4 link set-up, tubular a-arms and coil over's up front. This project will enable the car to be a daily driver, with lots of power to spare.
