Here at Engine Experts, quality is everything! That's why only one supplier will do. Feel free to visit them!! http://www.groomsengines.com/
All Grooms engine packages include the following quality components and proceedures.
BLOCKS
Dry cleaned at 650 degrees for 6 hours to remove rust and scale on the inside along with dirt and carbon on the outside
Magnafluxed and inspected for cracks
All threaded holes inspected and repaired
All cylinders bored perpendicular to main saddle on Rottler bar
Honed +/- .0002 in with a Sunnen hone
Deck surface is milled parallel to crank centerline to guarantee a consistent deck height, uniform compression and an ideal gasket surface
Main bore is align-honed to assure proper size and concentricity
After the block is thoroughly cleaned, new freeze plugs and oil plugs are installed
HEADS
Dry cleaned, magnafluxed and inspected for cracks
Guides are machined for oversized valves
Three-angle valve seats are cut with a Serdi machine
Resurfaced on a CBN cutter to create an ideal gasket surface
Oversized valves with hard chrome stems for best possible service and life
Computerized spring tester verifies open and close pressure
Hand-built with matching springs, premium valve stem seals and individually vacuum-tested
CONNECTING RODS
All are reconditioned; the big end resized and the small end checked for proper interference before being assembled to new pistons
All are checked for center to center twist and bend and corrected
CRANKSHAFTS
Dry cleaned, black-light inspected for cracks, straightened, oil holes wire-brushed and chamfered
Plunge ground +/- .0002 in
Polished to 8RA using QPAC machine that guarantees surface finish and proper geometry
ASSEMBLY
Each engine is hand-built by one technician who signs his name
New parts: pistons, rings, rod & main bearings, timing gears, chains, belts, valve keepers, oil pump or kit, oil pump screen (when available), EIS gasket set, rear seals, new flat tappet lifters, cams (new or reground), brass freeze plugs
Sim-tested with a special, dye-injected, heated oil to verify oil pressure, flow rate and delivery, then black-light inspected for external leaks, so we know it's right before it leaves the plant
