You will need to CC the dome if that's the measurement you are looking for.

You'll need to have the domes CC'd if they were custom cut to be sure.

I use a syringe and a pc of lexan with a hole in it.

Check the reference on the domes and post it here... that should tell you exactly what dome you have...Ada are pretty good with the marking of their dome (even custom domes).

i see

YA 21 33 l (crossed out) 36

 

[deftons56]

ya21xxl is 701.

760 would be ya76xxl.

If there is nothing after the L it also means the squish relief is flat with the domes (normally it's L15).
so yeah initially 701 domes 33cc modified in 36cc...

If you have custom cut domes with the original numbers crossed off, it might be wise to measure the squish band width with a set of calipers.

Consider measuring the diameter of the combustion chamber, that should tell you something. A 701 engine has a stock bore of 81mm. A 760 is 84mm stock. Dome size is 1 or more mm larger so you can go oversize on your cylinder bore.
