RAMPTECH® International DT466




  • RAMPTECH® engine builders always replace 100% of the pistons, rings, bearings, bushings, gaskets, and seals
  • All heads get new valves and are vacuum-tested to ensure the quality of the valve job
  • All heads are pressure-tested and upgraded to the latest style valve seal
  • RAMPTECH® engine builders always grind 100% of the camshafts’ lobes
  • All connecting rods are demagnetized
  • OEM components are used in all injection pumps
  • Core plugs are 100% stainless steel to avoid corrosion
  • Blocks, heads and crankshafts are 100% magnaflux- tested to avoid cracked components
  • Blocks are resurfaced and have counter bores machined to ensure proper sleeve protrusion and head gasket sealing
  • Connecting rods have new bushings installed, and both large and small ends are re-machined to OEM specifications
  • Crankshaft is checked for size, reground, as required, and polished to OEM specifications


All of RAMPTECH® Complete Drop-In Engines are 100% dyno tested prior to shipment. Computer controls ensure that each dyno test is conducted under standard repeatable settings. Every engine is run through a warm- up cycle, three separate loading segments simulating light, medium and heavy throttle conditions, maximum torque and horsepower tests, both high and low idle tests, and a black light leak-detection test with dyed oil, coolant, and fuel.
