Check cylinder head.  Includes chasing all threads including for sender unit as well as spark plug threads.
Running cylinder head on belt sander to true surface*.   Check squish band for proper gap and pocket width for compatibility with bore and piston size.
*Heads Severely warped or with wrong squish pockets/bands and improper or damaged pocket size will  require mill work that is an additional charge of $175-250.

All New bolts.   For the Cylinder head (Grade 8 bolts).  The rest of the block uses new grade 5 bolts along with Two New frost plugs

Crankshafts will be upgraded from the antiqued Saab OEM design large end bearings & cages replaced with an EXCLUSIVE MODERN DESIGNED connecting rods with an exclusive “Small End” lube hole for wrist pin bearing lube.  An Added BONUS is ALL rod kits are WEIGHT MATCHED!  (see photo)

The small end wrist pin bearing is upgraded to an EXCLUSIVE 18x22x29 mm “long-single” needle bearings in Silver coated cages. (see photo)

Large end bearing is POLYMER coat metal cage with 19 large needle bearings that are 28x35x16 mm.(see photo).  These are a modern snowmobile/Jet Ski type design for long life and capable of RPM’s of over 10,000!

The FOUR main bearings are a quality like SKF or FAG or KOYO) Bearing.  (No inferior Chinese Bearings)

*Wiseco Piston Engineering / ArmorGlide™ Coating Details (Pistons are $229 each)

Wiseco’s detailed skirt shapes and profiles are very specific to each application. Variable cam programming software developed in house allows Wiseco to produce high-performance shapes unique to only Wiseco. The skirt shape (barrel/cam) is one of the most functional areas on the piston, and provides stability and smooth operation in the cylinder bore. Stability is important for proper ring seal, reduced friction, and quiet operation. Each skirt shape is designed for a specific running clearance, based on coefficient of thermal expansion of the piston alloy. Some forging alloys expand more than casting alloys, but each Wiseco piston is designed with the proper installed clearance to produce the most power, least wear, and best seal at running temperature, for each application. Comparing installed clearances on cast vs forged parts is not indicative of the running clearance at temperature. Wiseco engineers have a strong background in all forms of racing applications, and produce the best shapes and designs in the industry.
