400" LSX 2000HP Short Block.
Available Qty: 0
$15,550.00Don't let the smaller displacement fool you, this 400" set up manifests itself as a multiple record setting base for your high performance turbo or supercharged build. By taking the stroke of the crank down to 3.750", you yield the advantage of a more rigid piece with conjunct benefits. The cranks overlap is reduced and piston speed is slowed, allowing for a more stable unit at high RPMs and substantial boost levels for long duration. Cylinder bores are taken to 4.125" bore and feature a much thicker ring land than your standard off the shelf piston, creating a more rugged and resilient part that is able to withstand high heat & high RPM in Supercharged /Turbocharged applications.
