hi, does anyone have a definitive answer on this, i've used the search function and results have come back ranging from 42cc-48.5cc. i will be measuring mine but won't be able to do it for a while, i need to work out my c/r and this is the only figure i don't have atm.

cheers

when new they are 48.5cc will be a bit less if its had a skim. measure it tho

ok cheers mate. my head is unskimmed and doesn't need a skim either

i read in an old fast ford that the 2 litre silvertop combustion chambers were 48cc and the blacktops were smaller due to having a dished piston

i will be measuring mine when its out of the car
