I need to know what the Combustion chamber size is on a cosworth head, so i can work out what the compression will be on my engine.

I cant find it anywhere on the net, im quite surprised. Im sure someone on here knows.

Any help appreciated

 

Can't help with the std figure , but unless you know that your head hasn't been skimmed, the best way is to measure your head to be absolutely sure of the compression ratio......

 

i only have a pinto head, not a cossie one. Ive not got the rods back yet either, so i dont know quelch depth etc etc.

 

nobody knows then????

 

well unless its standard and NEVER been skimmed,,,,,,,and most have

it will be no use, may as well make up a figure tbh
