Ah my apologies. When I talk about the oversize of the pistons I'm talking about it relative to the original bore of the Buick V6 which is 96.5mm. So a 0.5mm oversize to the Buick bore would be 97mm, 0.75mm oversize would be 97.25mm

Old thread, but I'm still a bit stuck on the compression ratio of these pistons. If the pistons have a dish of -13.3 and sit 3mm below deck, then wouldn't there be a -22.12cc added to that -13.3 dish? I get 7.48:1 with stock heads/gaskets and 7.86:1 with the thinnest Cometic .027" gasket.

I'm not sure the original user is still around and on the bbs regularly. You could try sending a PM.
