LS 427 Magnuson 1200HP
Designed for your 'hot street cars'
Our LS 427 Magnuson Engine Package is designed for your 'hot street cars' that are needing to make a bit more than our entry-level STAGE 1 combinations. These are a great option if you are 75%+ going to be street-driving the combination. We can provide these engines with the ability to drive around on pump gas nice-and-happy, then load the race gas calibration/pulley change and hit the track a few times per year.
We can add a HOLLEY or FUELTECH EFI system, ignition coils, and all the fuel system components as well. Wrap it up with our engine dyno-calibration on your choice of fuels, and you end up with a tested, proven engine combination for your ride!
