Lt1 Piston Rings

[Lynn]

LT1 piston rings 1970 (as well as 1969 350 horse 350 in Corvette)

Factory piston rings are 5/64, 5/64 and 1/8 correct?

Most of the aftermarket are 1/16, 1/16 & 1/8.

Top 2 rings are 5/64

Oil ring is 3/16.

Aftermarket are commonly 1/16 1/16 3/16m

1.5mm metric top rings becoming more common as well.

Thanks Eric. Of course, I should have said 3/16 for the oil. Was focusing on the top rings.
