as i was reading through the tech section i noticed that it says that 1200GX's have flat top pistons, is this correct, as my one has the same pistons as a standard 1200 a12.

Also as i am planning on using the standard 1200 block, crank, pistons, conrods. i was wondering if i should use the GX stuff, it doesnt really look any different to the standard stuff. except that the GX conrods look to be a it stronger, but also slightly heavier.

Any opinions?

This is news to me.

The article should be updated.

There were two GX pistons: low-gas and hi-gas. See: A12 GX Compression Readings

so it is normal for it to have standard pistons then.

anyone have enything to say about using the GX bottom end, compared to the standard one?

all I know is that the GX bottom ends were 10.0:1 compression ratio and they were balanced the block also had slight cut outs at the edges of the bores to allow clearance for the exhaust valve lip
