G200 Tech specs

[Benjamin]

Could someone please point me in the right direction for G200 specs including bore and stroke sizes, main journals and bearing sizes and such?

I need to determine whether the engine I am going to rebuild has been done before and therefore what parts I must order oversize.

Thanx

If pistons are oversize, it will say on their top.

Same goes with bearings, their size will be stamped on them, ie std means standard, 0.010 means 10 thou undersize, etc.

[tx1975]

all parts that arenrt standard will have there oversizes stamped into them (on top of pistions or back of bearing shells, end of cam shaft ) ie .20 thou = .5mm, u can only bore a G200 60thou safely then walls get to thin.
