HI
We are (intending) to use the Mahle forged piston +40' sold by precisionintl (SKU: PHO38006040MMS) in an engine that uses stock L27 ((1990-1995) commodore 3.8 engine pistons +40 thou.
***My question is : for using these Mahle pistons, in the water cooled engine that is +40 over, do builders taper or shape the cylinder bores (IE hourglass, bottleneck etc ) or no bore taper? These are air cooled cylinders, hot at the hot end, cooler at the crankcase...
With thanks, Glen.
