I'm working on a project and need some help.... Does anyone have accurate dimensional measurements for the block and cylinder head of a 1953 or newer (18bolt) chevy 235? Not just exterior dimensions, but also measurements for bore spacing, bolt holes, pushrod holes, coolant passages, port size and spacing, valve angles and spacing, ect... as indepth as possible. I have included examples of what I'm talking about. I know that it uses the standard chevy 4.40 inch bore spacing but the cylinders are not equally spaced due to main bearings, and I need exact measurements. Thanks
