'Just tell her you're trying to get more Iron in your diet...'
I just showed this to boardmember 66Dart a few weekends ago and the machine shop confirmed that we were dead on for chamber CC....
I think we cut the plexiglass/lexan at 6" x 6" to cover the chamber and then some. I mock it up to make sure the plastic has about 1" around the chamber. I then take and drill a hole (or a pair, one for inlet and one to expel air out of the chamber...) that's about 1/8"-3/16" near the top of the chamber (usually when upsidedown the head will have some tilt to it, which is good as the liquid will run to the bottom via gravity...).
When ready to measure, grab a cup of water and add some blue (or what ever color, darker is better under the shop lights) food coloring to the water (it's not romulan ale so don't drink it....). If it's a brand new head: I smear a dab of grease around the milled surface outside of the chamber (this will be the 'gasket' to seal the plastic to the head, apply a light amount, and keep it close to the chamber wall, not in the chamber), and put a little around the valves (if you are measuring up a core and the sets are shot or the valves are in bad shape this will keep the chamber liquid tight, if new it will protect the metal from rusting), if it's new head you can also lightly spray some WD-40 on the chamber walls to coat/protect it from rust since we are using water....
When that is done, apply plexiglass/plastic and make sure your hole(s) are at the top of the chamber and not in the 'greasy' O sealing it.
If you used clear plastic press on the plastic to make sure you have a nice sealed 'ring of grease' with no bubbles or breaks (not a good time to have a leak...).
Fill syringe to 60 CC typical chambers are 53-54 CC's so if doing a stock head 'sloowly' fill the chamber (I usually take about 90 seconds to fill the chamber trying to make sure I haven't spilled any liquid...)....When the liquid fills the chamber, but has a small 'pocket' of air near the hole...stop and make sure you put the last couple of drops in so it is 'filled' (a couple of drops off isn't too bad...more than 3 might be the .5CC's that puts you into 'ping city')..... read how much you have left in the syringe (i.e. 60CC syringe - 7.5CC of blue water left =52.5 CC....).....
place head over bucket or put a towel under the chamber, and pull the plastic off...wipe thoroughly with a nice clean rag, and you can do it again, or...try another chamber, to be consistent I recommend doing 3 (like #1, #3,and #6) and take an average for your calcs (might also tell you something about the milling of your head)....
Make sure to spray some WD, etc. into the chambers and on the milled surfaces after wiping down to combat rusting for storage/later assembly.
This is the quick and easy way...some guys will swear by the burette and graduated cylinder, but for $2 at the vet, and $3 at home depot, it sure beats the $20+ kit out of summit....
Hope that's as clear as mud, I hear some guys do this to their assembled short block, but I've never had reason to go that far...
let us know how you make out, I'll chack back in at 9:30 PST to see if you had some success....(and some fun too...)
