5.3 Vortec Ls ring gap compression ratio Hey, Im doing a Turbo 5.3 swap in my 87 GN.Im running the 6.0 lq4 heads.I set the top ring gap to.021 and the bottom ring to .026.Anybody have an idea on what my compression ratio will be?I will be running a 88mm turbo 1.05 housing.I will not be spraying but I will be using 93 and alky.I searched the thread and couldn't find an answer.Any input would be helpful.Thanks

Im not shure what the compression ratio is, but i think .021 is to tight on a turbo motor. What power are you going for? wet sump oil pan? what kinda turbo is it? what boost do you plan on running?
