Hi guys so I did they calculation for My engine, thia is a Toyota 5Efe engine, 1.5 4 Cylinders, I need a rod 8mm longer to get My ideal rod to stroke ratio. These are My resulta.
I searched in Google they theorycal block heigh and this is 187 MM
I found other video showing that I can calculate this before building they engine and get the posible surprise of a Bad piston to head clearance.
Stroke/2: 43.5MM, Rod lenght : 130mm, Comprensión heigh : 30mm , 43,5+130+30: 203.5mm
Theorycal - Actual : 187-203,5mm : -16.5mm
So here is My question... If originally the pistón is above the deck for 16.5mm and the ideal clearance is 1mm how it doesnt has contact with valves?? What I'm doing wrong?
Well, my research says 5efe short block height is 204mm so the piston at TDC would be 0.5 mm under the deck height. Moreover the pistons have huge intake valve pockets...
