Please feel free to use this compression ratio calculator as much as you like and please also post links to this page on the internet so that others may take advantage of it also. Be sure each piston is at TDC, right on the money.We are making this compression ratio calculator available to our valued customers and website visitors so that you can research various engine combinations to make the best possible car parts buying decision. But like I said, 0.040' across the pins (so the 'rock' of the piston in the bore is eliminated from the measurement) will be fine. This might be 0.043' w/the piston pushed as far down as you can rock it, and that will make the other side higher, say 0.037', if you follow me. I measure across the wrist pin, because the piston tends to rock in its bore, but at 0.040' across the pins, you'll be fine. If you can, borrow a depth mic, it will make the job SO much easier (shown below). You could even use a straight edge and feelers. Then, as long as you have a 'normal' amount of deviation (0.001'-0.002'- if over 0.003' I'd start looking for the cause), use the tightest figure to compute your quench for the engine's head gaskets. I believe it's worth it just for peace of mind, if nothing else. But checking all 8 piston heights will be the best route by far- it's not unusual for a rod to be 'long', and that's not something you want to find out during a WOT pass.

You want to check AT LEAST the 4 corner pistons- that will give you a figure for both sides (the sides can differ from one another) plus any front to rear deviation that could have occurred during manufacturing and machining of the block main saddles, decks and also the machining of the crankshaft and rods.
