36 dome pistons

[morymob]

I tried another forum awhile back & no answer. I have a set/new 36 77mm dome pistons i want to use in my '58's eng, anyone know how much this bumps up the compression??

I don't remember a name, been a few yrs but will get them out after this cold spell leaves. It would take quite a bump in piston top to get that hi with the large head chambers, i am hoping for a full point or with some mods i see to get close to 8:1.
