With pump gas? Or race fuel?
And to 94tegRS-An LS engine has 9.2:1 compression, not 9.6:1. But any B series rods and pistons (stock) can handle 12 PSI. The stock cylinder walls can handle 14-15 PSI. This is why it makes no sense to me why people just put in new rods and pistons when you can only run 3 PSI more than stock internals. If you are going to rebuild, get it relseeved.
