The system features an idler gear support plate attached to a second cover component inside surface. The system features an idler gear on an idler shaft. A camshaft gear is attached to a camshaft anterior end and a crankshaft gear is attached to a crankshaft anterior end. The back plate component is attached to a cylinder block front surface. The second cover component having the idler gear, the idler shaft, and the idler gear support plate located thereon is attached to the back plate component. The first cover component is attached to the back plate component next to the second cover component. ## Claims ### Claim 1 An automobile timing gear system (100) for use with a non-standard cylinder block that employs a raised camshaft location, wherein the system (100) comprises: (a) the non-standard cylinder block (150) having the raised camshaft location from a stock position, wherein a camshaft axis (152) is disposed offset from and parallel to a crankshaft axis (154);
