Machine work and assembly:

• All of our 427 cu. in. engines are custom built and dynoed in our engine building facility in Dawsonville, Ga. (Formerly Ernie Elliotts engine facility)
• We start with a new LS6 block and use a Darton Sleeve kit. They manufacture the highest quality sleeve available.
• A block pro five axis CNC vertical mill with fluid cooling is used for all machine work. This allows for tolerances to be held within one/half thousands of an inch.
• All machining operations are referenced off the crankshaft centerline.
• All required stress relieving is done using the formula 62 machine built by Stress Relief Engineering.
• Decking of blocks is accoomplished using a custom flycutter with CBN/PCD inserts.
• Every cam is computer checked for lift, duration, timing and centerline. Then it's degreed in the block for precise alignment.
• All rings are file finished, deburred and checked for proper arc.
• After engine installation, your vehicle is tuned on our chassis DynoJet dyno system.
