Use this kit with later model blocks using 10mm outer bolts. I cannot tell you with certainty what you have, only that about 1997 up "506" blocks typically used these. There is a potential for a split model year in 1997. We will not be responsible for incorrect orders.

Pistons available in +.020"(.5mm) and .030" bore sizes with .010" reduced compression height to allow for decking of the block or a slight reduction in compression ratio.Pistons come complete with rings. Please make note of which variety you need.

"Due to light demand we are not stocking these at present, but can get them in a relatively short time."- JK
