Description
Book SynopsisA complete practical guide on how to blueprint (optimise all aspects of specification) any 4-cylinder, four-stroke engine's short block to obtain maximum performance and reliability without wasting money on over-specced parts. Includes choosing components, crankshaft & conrod bearings, cylinder block, connecting rods, pistons, piston to valve clearances, camshaft, engine balancing, timing gear, lubrication system, professional check-build procedures and much more.
