way to measure CC volume?

[Asa]

something easier than the glass/plastic and the graduated cylinder method

i've got my C9 head ready to install... but i figured that i'd like to have the CR bumped up to about 9.5 before i installed it

thoughts?
i'm wondering about just droppin it off at the machinist, i think he'd be able to do it, but i dunno
he needs to play with it anyways

I've used a piece of glass/pexiglass and instead of a graduated cylinder, used a large syringe I got at a farm/ranch supply store (bet you could get one from a veterinarian too). Drill two holes in the plexiglass, start off with the syringe full, shoot water in one and let the air out the other. Whatever's gone from the syringe is your chamber cc.

I don't know an easier way, but if there is one I'm all ears...

Dust a chamber liberally with talc. Pack it solid with plasticine and slice off dead flush with the gasket face. Carefully pry out the plasticine and place in a beaker filled with 100ml of water already. Measure the new level while using a prodder to hold the plasticine fully underwater (it may float).

No oily mess! And you get to play with kid's stuff...

Play-dough (aka plasticine), that makes perfect sense - thanks!

And when you're done you can make Gumby...

Modeling clay also works for other things.

Piston to valve clearence. Put a little bit in the valve reliefs on the pistons. Lightly oil the valves. Install head, adjust valves, turn engine thru a couple of revolutions, remove head and check thickness of clay.

Oilpump screen to pan clearence. Cover screen with masking tape. Put a lump of clay on the tape. Rub a little oil on the inside of the pan. Set the pan on the engine and remove it. Check the thickness of clay for clearence.

On engines with huge ports it can be used to experiment with port shape and volume on the flow bench.

It also gives your customer's kid something to play with while you are talking motors.

- Especially if you keep it in a box labelled "Semtex".

...right next to the large crate labeled "C-4"...
