Trying to calc my compression ratio but have a discrepancy on the deck height portion. Classic Inlines small six specs for the 200 c.i.d. is .019. I measured mine using a dial caliper as a depth gauge and came up with an average of .052 per cylinder measured from top of block to piston top down the cylinder wall @ TDC. Why such a large discrepancy??? Also need to calculate the cc's of my stock (.040 overbore) dished pistons. Does anyone have a cc number for the dish volume? I measured the dish at approx. a 2 inch diameter by .1 deep in the dish center.
Current numbers as follows:
Cylinder diameter = 3.72
Stroke = 3.126
Combustion chamber volume 46 cc's
CC's of piston dish? Need to input negative number.
Head gasket crush thickness .053 per Classic Inlines Corteco gasket info, plus deck height measured @ .052 avg.=.105 total.
