G Compression ratio with aluminum pistons

kdl · May 4, 2017

Anyone know what the compression ratio would be in a styled g with a cyclone head after replacing pistons with the new aluminum ones available from most places (like sharps). No milling of head or block. Yes I know how to measure it, I am just asking if anyone knows . the g is not taken apart and I don't have new pistons right now . anyone know ?

M&W style pistons raise the compression to 6.75 to 1

Iirc both Extreme Tractor Parts and Murphy's custom build pistons to any compression ratio. The cam is worn and should be re-ground to compensate for wear and to match a higher compression ratio such as 7.5 to 1 or even 8 to 1
