LT1 pistons in 91 L98
I tore my L98 down recently for a rebuild. Ordered rings for the pistons, only to find out they wouldnt fit, so i tried the other type of rings for the L98, still not a fit. Looked over the pistons real good and noticed they were made by mahle. they are flat tops with 4 relief valves. I researched a bit and found the ZZ4 and LT1 both used this type of piston, but they called for the same rings as the L98 motor. 5/64 5/64 and i dont recall the oil ring size.
does anyone know more info about these mahle pistons? is there a part number on them somewhere i may be able to find?
