Your in so CA so I know for sure that you can go to a place called the Feed Barn. They sell syringes for horses that will hold 50 cc, be careful not to stick yourself, the needle is very sharp.
If you have a 2.4 liter engine, that’s 2.4/6 or 0.4 L per hole, ie 400cc.
Say you measure 45cc with the method I described. 400+45=445 take 445/45=9.888 That’s your exact comp ratio. No fancy calcs, just one simple measurement.
All the other info is usefull for calculating the compression ratio before you actually assemble the engine, and if your careful, they are exact, but the final measure should be done like I described, a double check, extreemly foolproof and accurate.
If your truly anal you can measure the 400cc as well. off by 4 cc, so what, thats only 1% or 0.1 for the comp ratio.
