Our years of engine building experience enable us to design and build the most powerful and durable engine packages available. All of Lingenfelter's engine packages include professional installation by experienced technicians for a factory installed appearance.
Engine Preparation and Blueprinting
LPE complete engine packages receive the following machine work prior to assembly. This ensures every engine meets our high quality standards. Some packages listed in our catalog do not include short block or rotating assembly modifications. See specific description for details.
Cylinder Block Blueprinting
Align hone checked and re-machined if needed Cylinders are bored to exact specifications on a Rottler F65 3 axis CNC Cylinders are precision honed on a Rottler HP6 with torque plates Deck surfaces are machined in reference to the crankshaft centerline Blocks are hand de-burred, bolt holes are checked and re-tapped
All internal parts are de-burred, hand washed and inspected Pistons, pins and connecting rods are pin fit to specification Crankshafts are computer balanced to within .5 grams or less Crankshaft oil holes are chamfered Crankshaft bearing surfaces are micro polished External parts are painted if required and prepped for assembly
Cylinder Head Porting & Preparation
Lingenfelter's CNC porting procedure is a computer controlled machining operation that duplicates exact details from a finished LPE hand ported cylinder head. Hand porting is a very labor intensive and time consuming procedure that takes years to perfect. By CNC porting the cylinder heads the high cost of hand porting is reduced, plus the CNC porting is more consistent and will produce better results. Each CNC ported cylinder head will have the exact same port and chamber configuration as the original master used to develop the CNC program.
Following porting each head receives:
Precision 3 angle valve job to maximize flow & provide extended life CC checking chamber size for correct compression Surfacing to insure deck flatness Professional assembly, setting spring height & retainer to guide clearance
LPE Blueprint and Assembly
Includes verification of LPE specifications of: Cylinder bore diameter Cylinder wall taper Piston diameter| Deck height of block Bearing clearances Crankshaft end play Piston to valve clearance Bolt torque specifications Lifter bore diameter Piston skirt taper Piston to wall clearance Piston ring end gap Rod side clearance Valve adjustment Degreeing the camshaft Correct oil pressure during priming
Road Testing and Dyno Testing
Because road testing and quality controls are some of LPE greatest concerns, our programming engineers will road test each vehicle. This unique performance verification check insures that each package stands up to LPE expectations and guarantees your complete satisfaction with the performance and drivability of your vehicle. Engine Dynamometer testing is available as an option to customers who wish to verify the complete engine package's horsepower and torque output. We will test your engine on a dyno fully equipped with all of the accessories to simulate the engine as it would be run in the car. Customers are supplied with a complete detailed graph of the engine performance results. Included in each package is a chassis dyno test which produces a graph depicting rear wheel horsepower and torque output of your vehicle.
