All of our engines are rebuilt with new rings and pistons, freeze plugs, lifters, timing components, crankshaft, oil pump, and gaskets.

We regrind, polish, and chamfer oil holes to rigid specifications on all crankshaft’s. Rods are checked for any bends or twists, resized and honed to O.E.M. specifications.

Valve seats are 3- angle cut for the perfect seal. Heads are cleaned, magnafluxed and pressure checked, and completely rebuilt.

Blocks are cleaned and magnafluxed to ensure unseen cracks do not cause premature failure. Then, to assure proper sealing, block decks and cylinder heads are resurfaced. Finally, we regrind and thoroughly inspect valves on stock engines, and we only use new valves on all performance engines.
