Are you sure, I thought it was 10.5:1. Not like this is a huge difference but everything I know about LT1's says that.

The blueprinted static compression ratio should be 10.44:1. You can round that off any way you want, I suppose. It's not a lot different than the LS1 engines being called "5.7L", while the actual displacement is only 345.6 CI, or 5.66L, and a "350" is only 349.8 CI, or a "396" is actually 402 CI.....

The LT4 engines had a static CR of 10.8:1.

Yea that makes sense. I did know that about the Lt4 though. I geuss GM has a habit of rounding up. I geuss most literature just keeps it simple.
